Abstract
IN 1928 the Aschheim-Zondek Test for the diagnosis of human pregnancy in urine was introduced1. In 1930, B. Zondek proposed a modification of this test for the diagnosis of equine pregnancy in the blood and in the urine2. The blood test is only feasible, however, between the 42nd and 125th days of pregnancy, after which the equine gonadotropin disappears from the blood3.
