Pregnancy Test | A Level Biology

In this video we find out how a home pregnancy test works. If she is pregnant, a woman will have hCG (human chorionic gonadotropin) hormone in her blood. We can test for this using antibodies for this hormone. In the pregnancy test, these antibodies are attached to blue beads. Suggestion for false positive scenario: abnormally high levels of hCG could be present in the urine, e.g. as a result of taking certain medication or because of a medical condition. This may cause the test to read positive when in fact there is no pregnancy. Suggestion for false negative scenario: test may be taken too early in pregnancy and hCG concentration in the urine is not high enough to be detected.
