The CoaguChek Test is a point-of-care device used o monitor and manage blood clotting time, specifically the international normalized ratio (INR), for individuals taking anticoagulant medications like warfarin. This test is not used to diagnose symptoms or medical conditions but to ensure that blood-thinning medication is within the target range to prevent clotting or bleeding issues. If you have concerns related to your INR levels or experience unusual symptoms while taking anticoagulants, consult your healthcare provider for evaluation and adjustment of your medication.
