Pregnancy tests are an easy and accurate way to find out the pregnant state. During pregnancy, several hormones with major roles are affected mostly. Significant changes in levels of HCG (Human chorionic gonadotropin hormone), estrogen, progesterone, and hPL (Human placental lactogen) are seen.
Early discovery has significant benefits for both mother and fetus. In the past, women became aware of their pregnancies only when the organogenesis of the fetus was almost conclud- ed. Now, it is possible to detect pregnancy 11-15 days after conception.
