Pregnancy Tests

Often in OB-GYN files, we come across pregnancy tests, let us get a general idea about what these are.

Pregnancy tests are tests that show if a woman is pregnant or not.  There are two types of pregnancy tests,
i) Test using urine sample.
ii) Test using blood sample.

Both of the above tests are for detecting the presence of a hormone called human chorionic gonadotropin (hCG).  This hormone is produced by the placenta shortly after the embryo attaches itself to the uterine lining and builds up rapidly in the pregnant woman's body in the first few days of pregnancy.It is this rapid shift in hormones that triggers most of the pregnancy symptoms.

Urine Tests:
i)  Performed at home.
ii)  Performed at clinic.

Blood Tests:
i)  Quantitative Blood Test (measures exact amount of hCG in blood).
ii)  Qualitative Blood Test (gives a yes or no answer regarding pregnant or not).
