COMPANY PROFILE / BIOSENSORS

Abbott
A diversified health-care company whose FreeStyle Libre and Lingo glucose sensors and i-STAT point-of-care tests put it squarely in biosensors

Abbott comes up in any discussion of biosensors because inside a global health-care group it runs both a large continuous glucose monitoring (CGM) business and a point-of-care testing business built on electrochemical sensors (i-STAT). In 2025 the group reported sales of US$44,328 million, of which the Diabetes Care business accounted for US$7,998 million (about 18%), according to its Form 10-K. FreeStyle Libre and Lingo are product names, not companies. This profile covers only the part of Abbott that touches biosensors, namely continuous glucose monitoring in Diabetes Care and point-of-care testing (POCT) in Diagnostics, using primary sources only. It is not a recommendation to use any product.

Sources: Form 10-K for 2025, Form 10-Q for the quarter ended 30 June 2026, Form 8-K results releases and the Exact Sciences acquisition filings, FDA 510(k) and De Novo documents and the recall database, Abbott's announcements and website, and ClinicalTrials.gov, used as primary material.

1. Abbott in 30 seconds, and where it stands in biosensors

LEGAL NAMEAbbott LaboratoriesAn Illinois corporation, incorporated in 1900
HEADQUARTERSAbbott Park, Illinois, U.S.100 Abbott Park Road. FDA documents place the diabetes business in Alameda, California
LISTINGSNew York Stock Exchange (ABT)Also listed on the SIX Swiss Exchange, per the 10-K
CATEGORY IN THIS FIELDDiabetes & continuous monitoring (primary)
In vitro diagnostics & POCT (secondary)
The group as a whole is a diversified health-care company with four segments
GROUP SALES (2025)US$44,328 millionAbout 115,000 employees (end of 2025)
DIABETES CARE SALES (2025)US$7,998 millionUS$6,805 million the year before. Part of the Medical Devices segment
DIAGNOSTICS SALES (2025)US$8,937 millionOf which point of care (i-STAT and others) was US$606 million
WHAT IT MEASURES, AND HOWGlucose in interstitial fluid
chemistry and immunoassay targets in whole blood
FDA documents: Libre uses amperometric measurement with glucose oxidase
The one thing to grasp first

Abbott is not a dedicated biosensor company; it is a diversified group in which two of its businesses (diabetes and diagnostics) are biosensor businesses. Diabetes Care is about 18% of group sales and about 37% of the Medical Devices segment Our calculation (US$7,998 million / US$44,328 million, and / US$21,387 million). In the 10-K, Diabetes Care is a sales category inside the Medical Devices segment, so operating profit and R&D spending for Diabetes Care alone are not disclosed Not yet confirmed. The Diagnostics segment, by contrast, discloses sales, R&D and operating earnings at the segment level Sourced.

2. The logo and how the name is written

A note on names: the legal name is Abbott Laboratories. The diabetes business operates as Abbott Diabetes Care (the applicant name in FDA documents, which list a site in Alameda, California). FreeStyle Libre, Libre Rio, Libre Duo, Lingo, i-STAT and ID NOW are product names, not companies. The logo was taken from the company's official website (abbott.com).

3. Where the company sits in the field

Four types of company involved in biosensors Even among "sensor companies", where they measure, who buys and how heavily they are regulated differ widely Diabetes & continuous monitoring In vitro diagnostics & POCT Wearables & consumer devices Materials & components Continuous glucose sensing Analyzers and reagents Daily sensing in devices Enzymes and electrodes Dexcom / Abbott Medtronic / Senseonics Roche / bioMérieux Siemens Healthineers Apple / Samsung Oura and others Toyobo / Paragraf and others Sensors and clinical data Tied to rules and payment Large installed base Tied to test demand Many users, wide reach Limited by medical claims Quality and consistency Tied to device demand Abbott is mainly diabetes and continuous monitoring, with in vitro diagnostics and POCT secondary Diabetes Care sales were US$7,998 million in 2025 (about 18% of the company); diagnostics includes i-STAT

4. Scale

Abbott is large, so group-wide figures are kept brief and the discussion centers on the parts that touch biosensors (Diabetes Care and Diagnostics). The figures below come from the 10-K Sourced.

Indicator (US$ million)202320242025Change in 2025

Rapid Diagnostics2,9972,454-18.1%COVID-19-related sales were US$285 million in 2025 and US$725 million in 2024

Of Diabetes Care's 2025 sales, US$3,181 million were in the U.S. and US$4,817 million outside it (results release for October to December 2025). In the first half of 2026, Diabetes Care sales were US$4,268 million (up 12.1% on the first half of 2025), of which April to June was US$2,188 million; CGM sales grew 11.0% as reported (9.5% on a comparable basis) in April to June Sourced. In October to December 2025, CGM sales were US$2.0 billion (up 15.0%) per the results release. The group had about 115,000 employees, 69% of them outside the U.S. (end of 2025), and 89 manufacturing sites worldwide, 33 in Medical Devices and 21 in Diagnostics.

A caution

From 2026 the Diagnostics categories changed (Core Laboratory, Rapid and Molecular, and Cancer Diagnostics from Exact Sciences). Of the US$3,092 million of Diagnostics sales in April to June 2026, US$919 million came from Exact Sciences (cancer tests), which Abbott acquired in March 2026 and which is outside the biosensor scope. The 2025 and 2026 Diagnostics sales are therefore not directly comparable. "Point of Care", which includes i-STAT, is not shown as a separate line in the 2026 filings (10-Q), and this article does not estimate it Not yet confirmed.

5. Resources committed to biosensors

Abbott discloses almost no people or investment figures specific to biosensors. Below, group-wide or segment-level values are separated from what could not be confirmed.

ResourceWhat primary sources confirmStatus
PeopleAbout 115,000 employees group-wide (31 December 2025; 69% outside the U.S.). Of 89 manufacturing sites, 33 are in Medical Devices and 21 in Diagnostics.

Acquisitions and investmentsAcquisition of Exact Sciences completed on 23 March 2026 (US$105 per share in cash; agreement signed 19 November 2025). Cash paid for business acquisitions in the first half of 2026 was US$19,962 million (10-Q), and US$20 billion of senior notes were issued in February to March 2026 (8-K). Exact Sciences is a cancer-testing company and outside the biosensor scope. No acquisitions or investments in diabetes or point of care were found in the sources checkedSourced / diabetes and POC deals not found
Universities, research institutes, public fundingClinicalTrials.gov lists 77 studies with Abbott Diabetes Care as sponsor or collaborator (43 as lead sponsor) and 17 for Abbott Point of Care (searched 4 October 2026).

Regulatory standing (confirmed in FDA's official documents)

ProductUse (as written in FDA documents)Category and numberDate
FreeStyle Libre 3 / Libre 2 family (including the Libre 2 Plus and Libre 3 Plus sensors)Management of diabetes. The Libre 2 Plus sensor is for ages 2 and older and is intended to communicate with other devices including automated insulin dosing (AID) systems. The FDA summary lists wear of up to 14 days for Libre 3 and up to 15 days for Libre 3 Plus510(k) clearance K233537 (product code QBJ). The original Libre 3 was K212132 (product code QLG)23 April 2024 (K212132: 26 May 2022)
LingoOver-the-counter (OTC) continuous glucose monitor for people 18 and older who are not on insulin. Helps detect euglycemic and dysglycemic levels and understand how diet and exercise relate to glucose excursions. The document says the user is not intended to take medical action on the output without consulting a qualified health care professional510(k) clearance K233655 (product code SAF)29 May 2024
Libre RioOTC continuous glucose monitor for people 18 and older who are not on insulin510(k) clearance K233861 (product code SBH)7 June 2024
Libre Duo 10 DayAn integrated system that measures glucose and ketones continuously (21 CFR 862.1354, product code SJD). In the company's announcement, for people with type 1 or type 2 diabetes aged 2 and older who use insulin or SGLT2 inhibitors (FDA's decision summary was not found)De Novo authorization DEN25004925 August 2026
i-STAT Crea cartridge (i-STAT 1)Quantification of creatinine in arterial, venous or capillary whole blood at the point of care or in a clinical laboratory. Prescription use510(k) clearance K261039 (product code CGL, enzymatic ion-based electrode)26 June 2026
i-STAT hs-TnI cartridge (i-STAT Alinity)Quantification of cardiac troponin I in whole blood or plasma, as an aid in the diagnosis of myocardial infarction, at the point of care or in a laboratory510(k) clearance K253051 (product code MMI)11 June 2026

The Libre products, Lingo and i-STAT are all 510(k) clearances; only Libre Duo is a De Novo authorization. None is a PMA approval. Abbott's U.S. Libre website states that the product is for prescription only (company statement). For Libre Duo, the company announced a CE mark in Europe in May 2026 (second-quarter results release). The status of approvals or certifications in Japan was not checked for this article Not yet confirmed.

A materials engineer's view: one sensor design sold through different doors, much as Dexcom does

The FDA summary for Lingo says the Lingo biosensor's hardware and technology are "based on" the already-cleared FreeStyle Libre 2 sensor (K222447), and that the user-contacting materials (patch mount, adhesive pad, plug components, introducer needle and sensor) are identical to Libre 2, so the biocompatibility evaluation under ISO 10993-1 carries over Sourced. The electron-beam sterilization validation (ISO 11137-1 and -2) done for Libre 2 is likewise treated as applicable. From the materials side, a well-developed combination of electrode, enzyme, adhesive and sterilization is being reused across prescription and over-the-counter products Not yet confirmed.

What could not be confirmed

Operating profit, R&D and capital expenditure for Diabetes Care alone / production capacity by Libre plant / 2026 sales of the point-of-care business (the categories changed) / FDA's decision summary for Libre Duo (not found on FDA's site as of 4 October 2026) / the status of approvals or certifications in Japan / public grant funding. None appears in the primary sources checked for this article.

8. What the company is aiming for in biosensors

This section separates what the company says it is aiming for from what this article reads into the record. An Inference is our interpretation of primary sources, not a statement by the company.

What can be readSupporting primary informationCategory
Extending what is measured from glucose to ketones as wellDe Novo authorization for Libre Duo (a new FDA category, 862.1354) and the CE mark (company announcement). The company calls it the "world's first" dual glucose-ketone sensor (company claim)Sourced (authorization) / Inference (future emphasis)
Having over-the-counter products in addition to prescription onesOTC 510(k) clearances for Lingo and Libre Rio (2024). The Lingo summary says it is based on the Libre 2 sensorSourced
Connecting to automated insulin delivery systems from several makersAugust 2026 announcement: planned integrations with Beta Bionics, Sequel Med Tech, Insulet, Tandem and MiniMedSourced (company plan)
Widening the menu of hand-held point-of-care cartridges510(k) clearances for i-STAT hs-TnI, Crea and others in 2024 to 2026; the 10-K's description of Diagnostics lists i-STATSourced (clearances) / Inference (policy)
Shifting the center of Diagnostics toward laboratory and cancer testingThe Exact Sciences acquisition (not biosensors). Rapid Diagnostics fell 18.1% in 2025 as COVID-19-related sales declinedSourced / Inference
One inference in detail

The reading that the company is "widening both what it measures and where it sells" rests on three kinds of authorization in about two years: prescription (Libre), over the counter (Lingo and Libre Rio) and ketone sensing (Libre Duo). The FDA summary for Lingo says its hardware and technology are based on the Libre 2 sensor and that the user-contacting materials are identical, so the basic sensor design is being reused for a different intended population Sourced. However, how Libre Duo measures ketones is not described in the FDA documents or company materials checked for this article, so whether it extends the Libre design or is a new design cannot be confirmed Not yet confirmed.

Sources: Form 10-K for 2025, Form 10-Q for April to June 2026, the company's announcements of 25 August and 16 July 2026, the Exact Sciences acquisition filings, and Dexcom's 10-K (exhibit list). Line style shows the type of relationship (navy = integration, including planned; orange = sales; dotted = acquisition; dash-dot = patent settlement and license). Most integrations are planned and do not show that they have taken place.

The integration partners named are those in the company's announcement of 25 August 2026 about Libre Duo. As for MiniMed, Dexcom's 10-K describes it as the entity into which Medtronic's diabetes business was separated. Abbott's announcement says only "an exclusive integration between Abbott-manufactured sensors and MiniMed systems," and neither supply performance nor contract terms were confirmed here Not yet confirmed. Integration partners for existing products such as Libre Rio and Lingo are not listed in the primary sources checked for this article.

10. Technologies, products and services

Abbott's biosensor-related products fall into two broad forms: on-body sensors that measure continuously (Libre, Lingo) and cartridge-based tests that measure whole blood in minutes at the point of care (i-STAT). The 10-K lists them as Diabetes Care products (in the Medical Devices segment) and point-of-care products (in Diagnostics) Sourced. Performance figures are marked as either manufacturer's stated values or FDA review documents; no ranking is made across products or tests.

ProductWhat the official documents sayNote
FreeStyle Libre 3 / 3 PlusFDA document (K233537): measures glucose in interstitial fluid as a current through a glucose oxidase reaction (amperometry). Test range 40 to 400 mg/dL. The sensor is single-use and powered by a silver oxide battery; the sensor tail is inserted under the skin with a needle that then retracts, and the sensor stays attached to the back of the upper arm with a medical-grade adhesive. Wear of up to 14 days for Libre 3 and up to 15 days for Libre 3 Plus. NFC is used to start a sensor and Bluetooth Low Energy to receive data on the appPrescription (the company's site says "prescription only")
FreeStyle Libre 2 / 2 PlusFDA document (K233537): a CGM with real-time alarms. The Libre 2 Plus sensor is for ages 2 and older. The Libre 2 Plus sensor has an 8-hour memory capacityIncludes a use intended to communicate with other devices
LingoFDA document (K233655): an OTC continuous glucose monitor for people 18 and older not on insulin. Hardware and technology are based on the FreeStyle Libre 2 (K222447) sensorSaid to help detect glucose levels and understand how diet and exercise relate to them
Libre RioFDA document (K233861): an OTC integrated CGM for people 18 and older not on insulinU.S. sales status was not checked here
Libre Duo 10 DayFDA: De Novo authorization (DEN250049), an integrated system measuring glucose and ketones continuously. Company announcement: wear of up to 10 days; 84.1% of adult sensors and 68.8% of pediatric sensors lasted the full durationU.S. launch planned for later in 2026 (company). Figures are the company's; conditions not confirmed
Blood glucose meters and test strips (FreeStyle and others)10-K: continuous and blood glucose monitoring systems, test strips and accessories under the FreeStyle and Libre brandsIndividual products and performance are not covered here
i-STAT / i-STAT Alinity10-K: cartridges for blood gases, chemistry, electrolytes, coagulation and immunoassay. FDA document (K261039): the creatinine cartridge is classified as an "enzymatic ion-based electrode" (product code CGL). K253051: hs-TnI is an aid in diagnosing myocardial infarctionWhole blood is tested at the bedside. The cartridges centre on electrochemical sensors (our reading of the K261039 classification name)
ID NOW, BinaxNOW, Afinion and others10-K: rapid molecular (isothermal nucleic acid amplification), lateral-flow and cardiometabolic tests. The ID NOW respiratory viral tests received 510(k) clearance on 31 August 2026 (K262747, product codes include OCC)Rapid immunoassay and molecular tests rather than biosensors; outside this article's scope
A materials engineer's view: electrode, adhesive, sterilization and process control all act at once

According to FDA review documents, Libre is a single-use sensor that measures the current from an enzyme (glucose oxidase) reaction at an electrode and runs on a silver oxide battery. It is held on the skin with a medical-grade adhesive, and the applicator's sub-component is electron-beam sterilized Sourced. The sensor tail goes under the skin with a needle that then retracts, and the adhesive is what holds the unit on the skin for up to 14 to 15 days. Reuse of the same design is documented in the Lingo FDA summary: the user-contacting materials (patch mount, adhesive pad, plug components, introducer needle, sensor) are said to be identical to Libre 2, and biocompatibility and electron-beam sterilization validation are carried over Sourced.

Process control, in turn, bears directly on performance. FDA's recall record gives the cause of the November 2025 correction as "a manufacturing process issue that may cause carbon build up in the sensor," which may result in incorrect low readings (root-cause category "process control"). For the July 2024 notice the category is "process design," and the trigger was reports of erroneously high readings Sourced. Which process or material was involved is not public. It is conceivable that an electrode material or a printing or deposition step was involved, but that is an Inference and has not been confirmed.

11. The risks this company carries

RiskDetailCategory
Recalls and correction noticesFDA's recall database lists correction notices for Libre sensors that started on 24 July 2024 (reports of erroneously high readings) and on 24 November 2025 (a manufacturing process issue that may cause carbon build-up and incorrect low readings). The quantity fields show 8,174 and 1,060,723 units respectively (for the product-number lines concerned). The notices describe steps for checking affected sensors and obtaining replacements.
