Clotting status

  • APTT
  • Fibrinogen
  • INR
  • PT

About this test

APTT and PT are two different measures of how long it takes blood to clot; INR standardises PT results and is commonly used to monitor people on warfarin. Fibrinogen is a protein involved in clotting. Together these four markers are commonly used to monitor anticoagulant treatment or to look into unexplained bleeding or clotting problems.

This test has no comparison group set in our data, so it cannot be benchmarked against directly named peers. It does, however, score very well on value: at £59 it is roughly 66% below the median price for similarly sized tests we track more broadly.

Collection convenience is the weak point: unlike several other Medichecks tests, there is no at-home route and no nurse-visit option either; you must attend a clinic in person for the venous draw. Trust signals and results and follow-up reflect Medichecks' standard facts: a Trustpilot rating of 4.5 from 2,477 reviews, UKAS ISO 15189 accredited partner labs, doctor review included as standard, and 25 years trading since 2001.

Who is it for?

This suits people already on warfarin or another anticoagulant who need regular monitoring, or those investigating unexplained bruising or bleeding, or a family history of a clotting disorder, ideally after discussing this with their GP. Because there is no at-home option, it will not suit you if you need a postal test; you must attend a clinic for the venous draw.

How it works

You need to attend a clinic in person for a venous blood draw, since the sample is not suitable for posting; per Medichecks, this can be done at Inuvi Clinic in London. There is no at-home collection option. The fact sheet does not detail further lab processing beyond the four markers measured. Results are back within 3 days, and every test comes with a doctor's review as standard.

Pros & cons

Pros

  • Covers four clotting markers (APTT, fibrinogen, INR and PT) in a single test.
  • At £59, roughly 66% below the typical price for similarly sized tests we track.
  • Results are reviewed by a doctor as standard.
  • Results are ready within 3 days.

Cons

  • No at-home collection option and no nurse-visit alternative; you must attend a clinic in person.
  • The sample cannot be posted, so travel to a specified clinic (Inuvi Clinic, London) is required.
  • There are no directly comparable named tests in our data to weigh this price against.

Our editorial score

Compare Health Test Score Anticoagulant monitoring test requiring a clinic visit
Editorial confidence: 10.0/10

This £59 test measures four clotting markers (APTT, fibrinogen, INR and PT), often used to monitor anticoagulant treatment such as warfarin, or to look into a bleeding or clotting problem. Unlike many Medichecks tests, there is no at-home option: samples are not suitable for posting, so you need to visit a clinic in person for a venous draw, with results reviewed by a doctor. At £59 it is roughly 66% below the typical price for similarly sized tests we track, though that comparison is not against any directly named peer.
