Important Investigations During Pregnancy

Doctors use two types of blood tests to check for pregnancy:

1. Quantitative blood test (or the beta hCG test) measures the exact amount of hCG in your blood. So it can find even tiny amounts of hCG. ...
2. Qualitative hCG blood tests just check to see if the pregnancy hormone is present or not. So it gives a yes or no answer.
