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.
In a healthy pregnancy, the level of hCG will rise rapidly and can be detected in your urine by a home pregnancy test 8 to 14 days after conception (fertilization) and in your blood by a test done at your practitionerâs office as early as 6 days after implantationâbefore your first missed menstrual period.
