RN or Nurse Practitioner? If youâre considering a nursing career, you may be wondering what the difference is between a registered nurse (RN) and a nurse practitioner (NP). What is the Difference Between an RN and an LVN?
  Answer     A blood test should be able to pick up the HCG in your blood at about 7 days after conception.     Some pregnancy tests say they can pick up â¦ HCG in your urine from about 7-10 days after conception, but most tests you have to wait to about 14 days-when your period is due.
They can pick up hCG earlier in a pregnancy than urine tests can. Blood tests can tell if you are pregnant about six to eight days after you ovulate. 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.2  So it can find even tiny amounts of hCG. 3  This makes it very accurate.f a HPT says you are pregnant, you should call your doctor right away. Your doctor can use a more sensitive test along with a pelvic exam to tell for sure if you're pregnant. Seeing your doctor early on in your pregnancy can help you and your baby stay healthy.
