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.
These more sensitive tests can pick up levels of HCG starting around 8 days after conception. However, HCG is detectible in the blood serum of only about 5% of pregnant women 8 days after conception. So remember, a negative result may in fact be a positive a few days later.Most early predictor tests say they can detect pregnancy about 10 days after ovulation (about 4 days before your expected period).However, the earlier you start testing, the higher chance of getting a false negative.
