hi I have read you guys talk about qualitative and quantitative pregn tests. What do these mean


Lena - September 15

Qualitative hCG test simply detects the presence of hCG in the blood. A quantitative test determines the concentration of hCG present in the blood. A qualitative test can simply tell you if you are or are not pregnant. A quantitive test is performed to measure increases in hCG and monitor the conceptus integrity. With a strong and viable conceptus, hCG levels should double every 36-48 hrs during early pregnancy.

Thanks lena. What is conceptus... ?

Conceptus refers to just the baby, or it can include baby, yolk sac, and placenta. Techinically its the latter, but is commonly used to describe the former as well.
