DiaPharma Factor X Chromogenic Assay: Understanding Its Value in Patient Care
Posted on: December 30, 2025

Key questions in managing warfarin patients include:
- What are the options for monitoring warfarin therapy in patients when the INR might not accurately reflect the level of anticoagulation, e.g. due to the presence of a strong Lupus Anticoagulant (LA) inhibitor?
- What test can measure the effect of warfarin to help ensure that these patients are in the therapeutic range?
The DiaPharma Factor X Kit uses a chromogenic method to measure Factor X (FX) levels as a readout of warfarin effect. The assay is not impacted by LA inhibitors and can therefore be used for monitoring warfarin therapy in patients when the INR is unreliable. This makes it a valuable tool for healthcare providers aiming to deliver high-quality care in the management of anticoagulant therapy.
Accurate measurements of factor X activity allow for more precise management of your patients’ anticoagulant therapy.
The DiaPharma Factor X Kit is accessible, FDA cleared, automatable, and available across the U.S.
