Blood Clotting Test (INR)

A low-cost INR (international normalised ratio) blood test that measures how quickly blood clots, used primarily to monitor people taking blood-thinning medication such as warfarin. Regular INR checks help keep anticoagulation within the intended therapeutic range. Self-pay with no referral — book and pay online, attend a collection point, receive a prompt result.

AGELLAB's INR test measures the international normalised ratio, a standardised measure of how long blood takes to clot. Its principal use is monitoring people on vitamin-K-antagonist anticoagulants such as warfarin, where the dose must keep the INR within a target therapeutic window — too low and the medication under-protects against clots, too high and bleeding risk rises. Because the right warfarin dose varies between individuals and can drift with diet, other medications and illness, regular INR testing is an essential part of safe anticoagulation. Offering it as an inexpensive, walk-up self-pay test gives people a convenient option for routine monitoring at a collection point near them, complementing the care of their prescribing physician — who remains responsible for interpreting the result and adjusting the dose. The analysis is performed in ISO 15189-accredited AGEL-group laboratories. The test is self-pay and consumer-facing: clients choose it in the AGELLAB e-shop, reserve a slot and pay online, then attend the Ostrava-Vítkovice collection point or any nationwide collection point for the blood draw. Results are issued promptly so that any dose adjustment can be discussed with the prescriber.
