1. a semisolidified mass, as of blood or lymph; called also coagulum.
2. coagulate. See also clotting.
blood clot a coagulum in the blood stream formed of an aggregation of blood factors, primarily platelets, and fibrin with entrapment of cellular elements; see also thrombus. Some authorities differentiate thrombus formation from simple coagulation or clot formation. Called also cruor.

dilute whole blood clot retraction test
an indirect measure of fibrinolytic activity. Whole blood is diluted with saline, chilled, then warmed. The time for clot retraction, and later clot lysis, is measured.
clot formation
a complex interaction, part of the phenomenon of blood clotting. The process is irreversible but the clot may be dissolved naturally.
clot lysis
the time required for a clot to lyse at 98.6°F (37°C) is a reflection of the plasmin content of the blood. Clot retraction and fibrinogen content of the blood sample are also influential.
clot retraction
the drawing away of a blood clot from a vessel wall, a function of thrombasthenin, released by blood platelets.
clot retraction test
a test for platelet numbers and function. Clotted whole blood should retract away from the sides of a glass tube in 1 to 2 hours.

Patient discussion about clot

Q. What causes blood clots? My father had a heart attack which was caused by a blood clot. Am I at risk for developing blood clots too? How do I prevent it from happening?

A. I found a website that checks your risks for inheriting your family's illness, including blood clots. They have a test you can do which is called "Free Risk Assessment for Thrombophilia":

Q. How can I prevent blood clots? I am 45 years old and am supposed to go on a business trip overseas. The flight itself is 12 hours long and then I have to continue traveling by bus. Could this cause me to have blood clots? If so, how can I prevent it?

A. Always walk as much as you can on the plane. Also, rotate your ankels in circles. Sometimes try to use your ankels and make the alphabet with them. Have fun..

Q. very dark blood clots @ first sight of period? At first sight of period, instead of normal rosy spotting it's brownish spotting followed by small clots.

A. totally agree with hottie, most likely that will be in normal range of variation. unless you feel some unusual pain, then you need to find medical advice. but it is also suggested for you to go to your ob-gyn doctor for a regular checkup anyway.
stay healthy always..

17) Premature clot lysis or hyperfibrinolysis can be identified by looking at the lysis parameter maximum lysis (ML) in the global ROTEM assays but is confirmed by the ML of the FIBTEM assay and/or the APTEM assay (which inhibits fibrinolysis in-vitro) to be true lysis versus a platelet-mediated clot retraction (Figure 3).
