A test for pregnancy [After Maurice H. Friedman (b. 1903), US physician.]
Reliable means for determining whether or not a woman is pregnant; it involves injecting some of her urine into an unmated female rabbit, and then, 2 days later, examining the ovaries of the rabbit. The finding of yellow bodies (corpora lutea) indicates that the woman is pregnant. Also called rabbit test.
A pregnancy test in which a sample of the woman’s urine is injected into an unmated female rabbit. After two days the rabbit is killed and its ovaries examined. If the woman is pregnant her urine will contain enough ovary-stimulating hormone (chorionic gonadotropin) to induce the development of corpora lutea in the ovaries of the rabbit.
