Types of Pregnancy Test
There are four basic types of pregnancy test. All of them rely on detecting the hormone human chorionic gonadotropin (hCG) in the body, which is only produced during pregnancy.
Home Pregnancy Test (HPT)
These can be bought at many stores and administered by a woman on her own. A chemical in the “stick” changes colors when exposed to hCG in urine. When administering an HPT, it is important to wait long enough after becoming pregnant, or you increase the risk of obtaining a false negative result.
Clinical Urine Pregnancy Test
This is essentially the same as a home pregnancy test, as it is urine-based. However, it comes with the added confidence of knowing the test is administered appropriately.
Blood Test – Qualitative
Urine-based pregnancy tests work because hCG from the blood is secreted in the urine. However, checking blood levels of hCG directly is an even more reliable way to determine pregnancy. By drawing a small sample from the mother, a lab can determine whether or not she has hCG in the blood, and thus whether or not she is pregnant with an even higher degree of certainty than the 99% that comes from a urine-based test.
