The hcg blood tests- How accurate are they?

[kbaby]

Are they 100% accurate? so if its a high hormone result does it definetly mean im pregnant or likewise could a low result mean im not?

how many tests have you had, they need to be repeated every 2 days, if they are rising, then that means you are PG, they really need to be doubling to take out any risk or concern, if they are not doubling but rising, a ectopic pg needs to be ruled out, once your HCG levels reach 1500 (I think) then at a scan, somEthing could be detected. If your HCg levels drop, then that is normally the sign of things not quite right. Sorry don't know your story - HTH.
