Before immunological pregnancy tests were developed in the 1960s, women relied on urine-based pregnancy tests using animals, ranging from mice to frogs. [1] [2] Advancements in medical technology have enabled women to accurately check their pregnancy status by using 'pee-on-a-stick' pregnancy test kits at home. Before these accessible and ...
The rabbit test became a widely used bioassay (animal-based test) to test for pregnancy. The term "rabbit test" was first recorded in 1949, and was the origin of a common euphemism, "the rabbit died", for a positive pregnancy test. [4] The phrase was, in fact, based on a common misconception about the test.
"We actually take x-rays of pregnant dogs all the time in veterinary medicine," they said. "It's a common practice to count the number of puppies so the owners can know what to expect." An ...
A study found that CTG monitoring didn't significantly improve or worsen the outcome, in terms of preventable child death, post birth mortality, of pregnancy for high risk mothers. But the evidence examined in the study is quite old and there have been significant changes in medical care since then.
A pregnant woman does not react, as she is producing the hormones in pregnancy; a subject who is not pregnant responds to the absence of the hormone by beginning a new menstrual cycle. While the test was (is) generally considered accurate, research advancements have replaced it with simpler techniques. [41]
One of the major advantages of the non-invasive prenatal testing is that the chance of a false positive result is very low. This accuracy is very important for the pregnant woman, as due to a high sensitivity and specificity of the testing, especially for Down syndrome, the invasive testing could be avoided, which includes the risk of a ...

A biophysical profile (BPP) is a prenatal ultrasound evaluation of fetal well-being involving a scoring system, [1] with the score being termed Manning's score. [2] It is often done when a non-stress test (NST) is non reactive, or for other obstetrical indications.
