Coagulation factors The remainder of the biochemical factors in the process of coagulation were largely discovered in the 20th century.

The process does not require the use of coagulation chemistry or high temperatures to produce solid threads from solution.

Factor V (pronounced factor five) is a protein of the coagulation system, rarely referred to as proaccelerin or labile factor.

Citrate is in liquid form in the tube and is used for coagulation tests, as well as in blood transfusion bags.

Local policy determines whether the patient or a coagulation specialist (pharmacist, nurse, general practitioner or hospital doctor) interprets the result and determines the dose of medication.

Protein coagulation is thought to limit uptake of these toxic materials by surrounding tissues, however it is this fact that limits its usefulness as a treatment agent in general.
