COMPANY PROFILE / BIOSENSORS

ARKRAY
A Kyoto specialist in diabetes testing equipment for laboratories, clinics and homes; blood glucose self-monitoring is one part, and financials are disclosed only for the group's sales

ARKRAY comes up in any discussion of biosensors because it is a Japanese specialist that has made single-use blood glucose sensors (test strips) and meters, based on an enzyme and an electrode, since the 1970s. According to the company profile on its website, group sales were ¥56.9 billion (fiscal year to October 2025) and the group had 2,091 employees (1 November 2025). The business is described in three layers: instruments for large hospitals, point-of-care testing for smaller hospitals and clinics, and self-monitoring meters for patients, with functional food ingredients on the side. According to FDA documents, the company's glucose test strips (GLUCOCARD W and Assure Titanium) are amperometric and use the enzyme glucose oxidase, and in Assure Titanium the mediator is hexaammineruthenium(III) chloride. That is a typical biosensor. This profile sets out what can be confirmed from official documents and what is not disclosed. No continuous glucose monitoring (CGM) product appears in the documents reviewed.

SELF-MONITORING BRANDGLUCOCARDIn FDA filings the same system sometimes appears with other brand names (such as ReliOn)
COMPANY NOTICE9 March 2026A website selling a non-invasive glucose meter that uses the ARKRAY name is declared unrelated
The one thing to grasp first

ARKRAY is best understood not as "a continuous glucose monitoring company" but as "a maker of diabetes-centered testing instruments and reagents for three places (laboratory, clinic and home), of which self-monitoring meters are one part" Our calculation. The website describes its businesses as for large hospitals and research institutions, for smaller hospitals and clinics, and for patients, but does not disclose sales for each Sourced. What share of group sales comes from self-monitoring meters could not be confirmed either Not yet confirmed.

2. The logo and how the name is written

A note on names: the legal entity is ARKRAY, Inc. (Arkray Kabushiki Kaisha in Japanese). The brand logo is set in lower case ("arkray"). The company was founded as Kyoto Daiichi Kagaku and took its present name in June 2000 (company history). The group has several companies, including ARKRAY Marketing, ARKRAY Factory and ARKRAY Infinity, so the applicant for a product's approval or certification differs from product to product. GLUCOCARD, Assure, ADAMS, AUTION, SPOTCHEM and The Lab are product or brand names, not company names. The logo image was taken from the company's official website.

The status of each product under the EU In Vitro Diagnostic Regulation (IVDR) could not be confirmed here Not yet confirmed. The FDA recall database has six records under ARKRAY's U.S. entities between 2007 and 2019 (titles and dates only; for example a 2007 Hypoguard blood glucose monitoring system, 2015 SPOTCHEM II test strips and 2019 software for the AUTION HYBRID) Sourced. For regulatory categories and how they differ from home use, see our explainer on medical device approval categories and home use.

A materials engineer's view: the enzyme and electrode that remain visible despite the silence

Even where financials are undisclosed, how materials are used in glucose measurement can be confirmed from FDA documents and company announcements. In the Assure Titanium strip, blood is drawn in by capillary action at the tip, where glucose oxidase (GOD) and hexaammineruthenium(III) chloride react to form ruthenium(II); the current from oxidizing it at the electrode is read by the meter and converted to a glucose value (FDA document). The laboratory glucose analyzer ADAMS Glucose GA-1180 likewise uses an enzyme membrane with immobilized GOD and a hydrogen peroxide electrode, measured by amperometry (company announcement) Sourced. From a materials standpoint, the stability of the enzyme, a mediator that is not disturbed by other substances in blood, the area and reproducibility of the electrode, and a flow path that draws in a fixed volume bear on accuracy in whole blood Not yet confirmed. However, the electrode materials, enzyme modifications and layer structure of the strip are not given in the documents retrieved. See our explainers on enzyme and electrode interface materials and on electrochemical sensors.

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. Inference marks interpretation drawn by this article from primary sources.

What can be readPrimary source behind itCategory
It aims at testing that links three places: laboratory, clinic and homeThe business page lists products in three layers (large hospitals, smaller hospitals and clinics, patients) and says it also provides data management systemsSourced (company explanation)
It is extending rapid tests (immunochromatography)The COVID-19 and influenza antigen kit (2024) and Rapid Chip BNP-II (2026)Sourced
It is widening beyond diabetes (oral health, cancer, veterinary care)SillHa (oral environment), the microRNA pancreatic-cancer research, and the veterinary brand thinkaSourced
It is letting go of an HbA1c reagent while focusing on instruments and rapid testsThe agreement to transfer Sanku HbA1c; new instruments and rapid tests launched around the same timeSourced (transfer) / Inference (where it is focusing)
It has probably not entered continuous glucose monitoring (CGM)No CGM appears in the official product information or news. It states that a non-invasive glucose meter using its name is unrelatedInference (an absence read as meaning; whether development exists is unknown)
One inference, explained in more detail

The reading that "ARKRAY has probably not entered CGM" rests on the absence of CGM from the official product list and news. The website's product information lists large instruments, small instruments, health screening, healthcare, diabetes treatment support (self-monitoring meters, lancing devices and management apps) and veterinary care, but no wearable continuous measurement product Sourced. The March 2026 notice also says that a non-invasive glucose meter using the company name has "nothing to do with" it. However, that does not show that no development or partnership exists outside the website. This article confirmed only the absence Not yet confirmed.

9. Map of partnerships in biosensors

Investments, joint venture, research and transfer around ARKRAY Only relationships stated in the company history or news; no press-based relationships ARKRAY Boditech Med (Korea) Capital alliance (2013) ELITECH France Investment (2009) MC Kenkyusho Business and capital tie (2004) ARKRAY PIRAMAL Medical Joint venture in India (2007) Shino-Test HbA1c reagent (agreed) Kyoto Univ. and 13 sites Pancreatic cancer miRNA (2024) PHC Corporation Supplies meters (OEM) ARKRAY's own documents name no supplier of sensor parts Investment / capital alliance Business transfer Joint venture / joint research Supply
Fig. 2 Investments, a joint venture, joint research and a business transfer around ARKRAY. Sources: the company history, the official announcements of 28 August 2024 and 5 September 2025, and the 2026 company overview of PHC Holdings. Dotted lines show investments and capital alliances, dashed lines a business transfer, solid navy lines a joint venture or joint research, and orange a supply relationship. Only relationships stated in official documents are shown (the PHC link is stated in PHC's document, not in ARKRAY's). The 2015 business transfer from Span Diagnostics is left out to keep the figure simple (see the text).

The relationships that can be confirmed are investments and capital alliances, a joint venture, a business transfer, joint research and a supply link from PHC. PHC Holdings' 2026 company overview lists, among the OEM supply that PHC Corporation provides to domestic partners, a self-monitoring blood glucose system with ARKRAY, Inc. as the delivery destination Sourced. ARKRAY's own documents do not mention this supply, so which model it covers, and for which market, could not be confirmed (in FDA filings, GLUCOCARD W and others are filed in the name of Arkray Factory, Inc.) Not yet confirmed. No other supplier of test strips or parts is named in ARKRAY's documents. In FDA filings, the same blood glucose system is listed under more than one brand, such as "GLUCOCARD 01" and "ReliOn Confirm", but the sales relationship behind that could not be confirmed from the official documents retrieved Not yet confirmed.

10. Technologies, products and services

The product information on the company website is divided into large instruments, small instruments, health screening, healthcare, diabetes treatment support and veterinary care. The table focuses on those closest to biosensors. All figures are manufacturer's stated values; test conditions and editions differ, so no ranking is made between products, or against other companies' products Sourced.

CategoryWhat the official sources sayComment
Home: GLUCOCARD self-monitoring metersGLUCOCARD Prime: about 0.6 µL of blood; measurement time 5.5 seconds (G sensor) or 7 seconds (Prime sensor) after the drop is detected. The company states conformity with ISO 15197:2013. Also GLUCOCARD Plus Care, the "Natureret" lancing device and the smartphone app "Smart e-SMBG" with a cloud serviceManufacturer's stated values.

Oral, veterinary and food ingredientsThe oral-environment system SillHa (hemoglobin in mouth rinse), the veterinary brand thinka (glucose meters and urine analyzers for dogs and cats, Vcheck V200 and others) and functional food ingredients (anti-glycation and others)Areas beyond diabetes
A materials engineer's view: measuring glucose in whole blood with a small strip

Electrochemical measurement of glucose in whole blood stacks several materials problems: the stability of the enzyme (GOD and others), the choice of mediator so that other substances in blood do not interfere, the area and reproducibility of the electrode, and a capillary flow path that draws in a fixed volume of blood. The FDA document records that Assure Titanium was evaluated across a claimed hematocrit range of 10 to 70% and that the effect of interfering substances was assessed Sourced. How a strip's design keeps the effects of blood thickness (hematocrit) and co-existing drugs and substances small is the central materials question for this kind of device Not yet confirmed. However, the electrode materials, the type and immobilization of the enzyme, and the layer structure of the strip are not given in the documents retrieved. The laboratory GA-1180 is stated to use "an enzyme membrane with immobilized GOD and a hydrogen peroxide electrode", which shows that enzyme immobilization technology underlies the product.

12. Glossary

Self-monitoring of blood glucose (SMBG)
Measuring one's own blood glucose from a small blood sample, usually from a fingertip, with a meter and a single-use test strip (sensor). How to read results and use them in treatment depends on the instructions of a healthcare professional.
HbA1c (glycohemoglobin)
Hemoglobin in red blood cells to which glucose has bound. A test item that reflects blood glucose over roughly the previous one to two months.
Glycated albumin
Albumin in the blood to which glucose has bound. A test item that reflects blood glucose over a shorter period than HbA1c.
Amperometry
A method in which a voltage is applied to an electrode and concentration is derived from the current that flows in the reaction. Widely used in glucose meters.
Mediator
A substance that carries electrons between the enzyme and the electrode. In Assure Titanium it is hexaammineruthenium(III) (FDA document).
Dry chemistry
A format in which reagents are carried on a dry strip or film, so that blood and other samples can be tested without liquid reagents.
Immunochromatography
A method that uses antibodies to capture and detect a target substance as the sample flows along a test strip.
BNP
Brain natriuretic peptide, a protein measured in blood in connection with strain on the heart. How to read the result is a matter for healthcare professionals.
ISO 15197
The international standard for the performance of blood glucose monitoring systems. ARKRAY states conformity with the 2013 edition.
510(k) clearance
The U.S. FDA route for devices found substantially equivalent to a device already on the market. Distinct from PMA approval and De Novo authorization. "Dual Track" means a 510(k) filed together with a CLIA waiver application.
In vitro diagnostic reagent (Japan)

Every figure in this article comes from ARKRAY's website and official announcements and from FDA public documents. No research-firm estimates or press-based figures have been used. Passages marked "Inference" are this article's interpretation of primary sources, not statements made by the company. ARKRAY does not state in official documents whether it is listed or give detailed financials, so these are recorded as "not disclosed" or "not confirmed".
