What happens to during Clot Retraction? Nid help..?

Question

What happens during clot retraction, im having a hard time understanding it.. Pls help me!!

Answer 1

way back years ago the lab had a test called a clot retraction.
a tube of blood was drawn in a plain red top 10ml tube. it was placed in a rack at room temperature. the fibrinogen in the blood would convert to fibrin and form a solid clot. as time passed the clot would withdraw from the sides of the glass tube and the fibrin would compress leaving a clear area above the clot (which was serum). the test was expressed in percent retraction. the average is about 40 to 60 percent i think. it has been ages since the lab has used this test. fibrinogen is measured by more advanced methods these days. very few manual tests are done any more. the vast majority are automated.

Answer 2

Clot consists of fibrin. Fibrin shrinks losing water and white cells into the internal environment. The clot totally becomes a foreign body and gets organised as fibrous or calcified body.
