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 blood test will show if you are pregnant or not 7 days following conception. I believe that a blood test can show resolts two weeks after conception. And yes they will detect it before a home test will. A blood test can detect as early as 4 weeks and a urine test as early as 6 weeks. As early as 10 days after conception, definitely by the time you've missed your period.
