What is the clotting substance in the blood called?
Breus' mole and well-being of the foetus. Breus' mole Breus' mole (Ova tuberculosa, massive mole) is a massive, subchorionic, tuberous hematoma, formed out of maternal blood in the uterus in pregnancy. It was first described by Karl Breus in 1892. It is a rare disease, with an incidence of 1 in 1200 placentas. Women with cardiac problems, disorders of circulation, monosomy, hypertension and diabetes are predisposed to Breus' mole. The mole is formed as a sub-chorionic hematoma, formed out of the intervillous blood, causing progressive accumulation of the clotting substance called fibrin with increasing gestational age.

Clotting time Clotting time Clotting time is the time required for a sample of blood to coagulate in vitro under standard conditions. There are various methods for determining the clotting time, the most common being the capillary tube method. It is affected by calcium ion levels and many diseases. Normal value of clotting time is 8 to 15 minutes. For the measurement of clotting time by test tube method, blood is placed in a glass test tube and kept at 37° C. The required time is measured for the blood to clot. There are several other methods, including testing for those on
