Pregnancy test

How do home pregnancy tests work. Once the egg is fertilized, the egg and developing placenta begin to release hCG (Human Chorionic Gonadotropin). The presence of hCG will help in the production of progesterone, a hormone essential for a hospitable environment for the implanted egg. The hormone hCG will begin to show up in a woman's blood and urine. This hormone is what the home pregnancy test look for in a woman’s urine to determine a positive or negative result. If you go to your doctor’s office for a pregnancy test, they will first take a urine test that detects the same hormone as the home pregnancy tests. The doctor’s urine test is slightly more effective, statistically, because you have professional administering it who is less likely to make mistakes. The doctor can also offer a blood test, which is more precise, to confirm your pregnancy.
