Rabbit test
Rabbit Test
Rabbit test (/ˈræbɪt tɛst/), also known as the Friedman test, is a historical biological test used to determine pregnancy. The term originates from the early 20th century when the test was first developed.
Etymology
The term "rabbit test" comes from the misconception that the injected rabbit would die if the woman was pregnant. In reality, all rabbits used in the test would die, as they had to be dissected to examine the effects on their ovaries. The term "Friedman test" is named after Maurice Harold Friedman, the American endocrinologist who developed the test.
Procedure
The rabbit test involved injecting a woman's urine into a female rabbit. The rabbit was then observed for several days. If the rabbit's ovaries showed changes, it was an indication that the woman was pregnant. This was because the human chorionic gonadotropin (hCG) hormone, present in the urine of pregnant women, would cause these changes.
