What is a Pregnancy Blood Test?

laura lee pregnancy approachOne question that I am often asked during my monthly group conceiving classes is:

What exactly is a pregnancy blood test and how does it work?

Simply put, a pregnancy blood test is an alternate (and more accurate) way of confirming a pregnancy by testing the level of hCG in your blood. Most of the time, these types of tests not only test for hCG but also measures the exact amount of hCG in your bloodstream.  Knowing this information, your doctor can determine the exact age of the growing fetus.
