The 2021 global market for coagulation tests (lab-based and all POC) neared 4 billion last year. PT and d-dimer tests lead revenues, per Kalorama’s In Vitro Diagnostic Business Outlook. The publication focuses on one aspect of the IVD market in each issue. The publication comes out 2 times a month. This issue focused on coagulation. Hemostasis (coagulation) is a complex process in which multiple enzymes and proteins regulate blood flow and clot formation. Coagulation (clot formation), fibrinolysis and platelet aggregation are a part of this process. Fibrinolysis refers to the breakup of blood clots. It is a normal body process that keeps naturally-occurring blood clots from growing and causing problems.
Anticoagulant drugs help prevent blood platelets from sticking or clumping together, reducing the likelihood that arteries will be blocked by a clot, leading to a stroke or heart attack.

The most widely used drug is Coumadin (Warfarin) that is prescribed for patients with atrial fibrillation, artificial valves and phlebitis. People on warfarin need to have their blood monitored regularly (sometimes weekly and sometimes monthly) to ensure that they are taking the right dosage to avoid clotting if the dosage is too low and also unintentional bleeding when the dosage is too high. This is done with a blood clotting test known as the International Normalized Ratio (INR, formerly known as the Prothrombin Time test).
Proponents of PT/INR self-testing claim that daily or weekly testing at home helps patients maintain better anticoagulant activity – not too much and not too little.
There are newer oral anticoagulants on the market, such as rivaroxaban (Xarelto), apixaban (Eliquis) and dabigatran (Pradaxa). They are at least as safe and effective as warfarin, and they do not require regular coagulation monitoring with a PT/INR. However, hematologists will use immunoassays to measure the amount of drug concentration in a patient’s blood to assure that the amount of drug is in the therapeutic range. This is akin to therapeutic drug monitoring by immunoassay of antibiotics (gentamicin), antiepileptics (such as carbamazepine, phenytoin and valproic acid), and antipsychotics (such as pimozide and clozapine).
Companies in the market include:
- Abbott Diagnostics
- ARUP Laboratories
- Diagnostica Stago
- Diagon Ltd
- HUMAN Diagnostics

Roche launched the CoaguChek XS mPOC app for use with the CoaguChek XS meter. The app, CoaguChek Vantus, makes the Bluetooth-enabled PT/INR reporting offered by CoaguChek Patient Services more convenient and accessible by allowing patients to use their own iOS device (iPhone or iPad). The app is available exclusively to patients who test PT/INR with the support of CoaguChek Patient Services. Wireless-enabled patient self-testing with CoaguChek Patient Services enables HCPs to confidently monitor reported patient PT/INR data remotely.
For lab-based testing, Roche received FDA clearance to market its multiplex Factor II and Factor V test for use on the Cobas 4800 system, which performs real-time PCR analysis for mid- to high-volume labs. Roche noted that the clearance expands the menu of the Cobas 4800 system and enables labs to consolidate genomics, oncology, microbiology, and virology testing onto a single platform. Roche added that the test also complements a recent CE approval of the Cobas t 511 and Cobas t 711 coagulation analyzers, which are suitable for central labs performing coagulation and thrombophilia testing.
An arrangement between Dade Behring (now part of Siemens Healthineers) in 1995 introduced Sysmex’s coagulation analyzers to the U.S. market. In 2012, the companies announced that the partnership was extended to 2018. In April 2016, Sysmex and Siemens announced an extension to their partnership through at least 2020. The contract extension adds a minimum of two additional years to the global supply, distributorship, and sales and service agreement for hemostasis products. The companies, which began collaborating more than 20 years ago, also agreed to continue joint hemostasis product development activities that will streamline and optimize testing in laboratories throughout the world.
In the past few years alone, the companies have introduced several advanced INNOVANCE reagents and multiple new platforms for various laboratory settings, including the recent worldwide launch of the Sysmex CS-2500 System, and the U.S. launch of the Sysmex CS-5100 System with optional track-based automation.
In July 2020, Sysmex launched new products including the Automated Blood Coagulation Analyzers CN-6500/CN-3500. These new offerings from Sysmex come with a measuring unit using the chemiluminescence enzyme immunoassay methodology (CLEIA), which the company cultivated in its Automated Immunoassay Systems HISCL-5000/HISCL 800 (HISCL), on top of the unique features of the Automated Blood Coagulation Analyzers CN-6000/CN-3000, making it possible to measure blood coagulation testing parameters, including molecular markers for blood coagulation with a single device.
