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.
A qualitative blood test simply checks to see if hCG is present. It gives a âyesâ or ânoâ answer. Doctors often order these tests to confirm pregnancy as early as 10 days after a missed period. Some tests can detect hCG much earlier. A qualitative blood test is seldom used to quickly confirm pregnancy since it takes a few days longer.
