Claims (9)
1. A radioimmunoassay anti-serum comprising human chorionic gonadotropin-^ -absorbed anti-human chorionic gonadotropin-serum.
2. The anti-serum oJ? Claim 1 wherein each milliliter of anti-human chorionic gonadotropin-(3 serum was absorbed with 0.1 to 0.4 milligrams of human chorionic gonadotropin-d .
3. A radioimmunological method for quantitatively determining human chorionic gonadotropin in a specimen containing human chorionic gonadotropin in the presence of. up to about 10 times the amount in m I.U./ml. of luteinizing hormone, which comprises providing a human chorionic gonadotropin- (^-absorbed anti-human chorionic gonadotropin-^ serum plus radioimmunolo-gically labeled human chorionic gonadotropin-^ system and determining the degree of inhibition produced by said specimen, on the radioimmunological reaction between said system components, the observed inhibition being substantially due to human chorionic gonadotropin.
4. The method of Claim 3 wherein the inhibition is determined by effecting a radioimmunological assay of the specimen and comparing the results with a known standard.
5. The method of Claim 3 wherein each milliliter of. anti-human chorionic gonadotropin- serum was absorbed with 0.1 to 0.4 milligrams of human chorionic gonadotropin-^.
6. A method for radioimmunologically ascertaining pregnancy which comprises effecting the method of claim 3 using a sample of urine as specimen, pregnancy being positively ascertained when the inhibition is greater than about 20%.
7. A method for radioimmunologically ascertaining pregnancy which comprises effecting the method of claim 5 using a sample of urine as specimen, pregnancy being positively ascertained when the inhibition is greater than about 0%.
8. A method for obtaining an anti-serum capable of radio-immunologically discriminating human chorionic gonadotropin in the presence of up to about 10 times the amount in m I.U./ ml. of luteinizing hormone which comprises obtaining anti-
9. The method, of Claim 8 vherein each milliliter of anti-human chorionic gonadotropin- serum was absorbed v/ith 0.1 to 0.4 milligrams of human chorionic gonadotropin-c .
