1. Method for determining the concentration of luteinizing hormone in the body fluid of a woman, which comprises reacting the body fluid of the woman with a predetermined amount of anti-human chorionic gonadotropin and with a composition of human chorionic gonadotropin coupled to red blood cells by means of glutaraldehyde and also containing a stabilizing effective amount of gelatin, whereby hemagglutination occurs when said body fluid contains an amount of luteinizing hormone less than the amount which will react with all of said anti-human chorionic gonadotropin and no hemagglutination occurs when the amount of said luteinizing hormone in said body fluid is greater than the amount which will react with all of said predetermined amount of anti-human chorionic gonadotropin.
