ABSTRACT:
A clot mass condition of blood is evaluated by initially forming the clot in the sample of the blood and thereafter allowing the clot to condense. The initial formation of the clot is determined by measuring the drop time of a reciprocated indicator device upon which the clot is formed. The condensation of the clot is determined by measuring the stabilized and increased drop time of the indicator device after the initial clot formation has occurred. The clot mass is related to the quantity of fibrinogen in the blood sample which polymerizes in the clot. Clot condensation results in the clot being substantially only fibrinogen, so the stabilized condensation time is related to the fibrinogen concentration in the blood sample.
