The method of guantitative immunoenzymatic determination of beta 1-G-globulin (TSG) in the blood serum has been developed. The sensitivity of the method is 6 ng/ml TSG. It has been shown that elevated levels (12-100 ng/ml and higher) are usually observed in trophoblastic tumours of the uterus. The TSG ectopic synthesis is found to proceed in some tumours of the gastrointestinal tract and testicular teratoblastomas.
