Soluble fibrin-monomer complexes in normal pregnancy.

The protamine sulphate test of Lipinski and Worovski was used by the authors investigate the amount of soluble fibrin-monomer complexes (SFMC) in women with normal pregnancy. Those complexes were found to increase considerably during the second and even more the third trimester of pregnancy. The high level of SFMC in plasma, probably, reflected increased activity of blood coagulability toward the end of normal pregnancy.
