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.
If you are pregnant, then the blood pregnancy test is usually positive within 3-4 days after implantation or about 10-11 days after fertilization and ovulation. The urine pregnancy test is positive several days after the blood test becomes positive.etection of hCG depends on timing of implantation so hCG can normally be detected in the blood between 9 and 16 days after ovulation (HPT: 12-19 days after ovulation).
