Abstract: | Immunoenzymatic method for the determination of new ovarian-metastatic antigen-8 in human blood serum was worked out. OMA-8 level was studied in blood serum of 40 healthy women, 40 healthy men, 16 neonates, 33 pregnant women, 103 patients with genital tumours. It was found out that OMA-8 level in blood serum of healthy women changed between 2 to 15.4 micrograms/l, in men between 5-17.0 microgramS/l. OMA-8 concentration higher than 15.4 micrograms/ was considered elevated. The elevated OMA-8 level was marked in neonates (100%) and in pregnant (39.3%). High level was discovered in the amniotic fluid. |
