Study on a blood test for prolonged clotting time
Part of Blood & lymphatic, Genetic & congenital, Heart & circulation clinical trials.
This study looks at a special blood test (clot waveform analysis) to see if it can help doctors better understand why some people have a prolonged clotting time. This might help them find the cause more quickly and accurately.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You had a blood test showing a prolonged clotting time (APTT ratio 1.25 or higher).
- Your other clotting test (prothrombin time, or PT) was normal.
- Your blood sample was tested on a specific machine (ACL TOP) with a specific reagent (SynthASil).
- Your blood sample was collected and handled according to strict study guidelines.
- You were being checked before surgery or as part of routine medical care.

This study measures how long it takes for your blood to clot while you are taking anticoagulant medication. The purpose is to understand typical clotting times for patients on these drugs, which may help improve future monitoring or treatment decisions.
This trial uses stored blood samples to see how well different lab tests measure clotting when someone has a factor deficiency (like low levels of clotting proteins) or liver damage. It may help doctors choose the most accurate test for these situations.
This study tests a new blood test called ClotChek™ to see how well it works for people taking direct oral anticoagulants (DOACs), a type of blood thinner. You would give a blood sample, and the test may help doctors better monitor your medication.
This study observes patients with blood clotting or bleeding disorders over time to collect health information and improve care.
This study is for children who are having surgery or a procedure with anesthesia. It tests a new device that checks how well their blood clots, to help find normal ranges for kids of different ages.
This study looks at how the body stops bleeding or forms clots in people with bleeding or clotting disorders. It may help researchers understand these conditions better and improve evaluation tests.
