How accurate are blood pregnancy test?

Public Comments

1. ummm......Very accurate since they do a specific HCG count!
2. more accurate then the ones you urinate thats for sure. Its pretty hard to be wrong in a blood pregnancy test because they're looking for specifics.
3. I would say 100%, if only done after certain time (I think 7 days after fertilization, but not sure about timing).
4. If it is done 3-5 weeks after conception - 100%
5. I used to think 100%. But my current pregnancy they got my levels wrong twice and said I would miscarry since the levels were decreasing. But it was a lab error as we found out with an ultrasound. Id trust an ultrasound over a blood test.
