Can a blood test determine a pregnancy when a urine test and home test said negative?
The blood test will detect pregnancy earlier than a home pregnancy test, but if you have waited long enough for the home test to be accurate (this varies between tests, but some are accurate a few days after a missed period...the home test boxes will tell you this information), then you could have the blood test IF you think you got a false-negative on your home test. It would be less expensive to repeat the home test than to go for a blood test. Maybe try a different brand? A blood test will determine a pregnancy if you are pregnant, but if your home test was "reliable" (i.e. negative) then I would not bother with the blood test.
You may want to ask a more specific question. I could think you are worried about having a blood test for a physical or insurance qualification...whatever...and you want to make sure your results would be negative. Unless they are specifically testing for pregnancy, they will not be told by the lab "oh, by the way, she is pregnant."
Then again, what immediately struck my heart was the fact that you may be trying to get pregnant and when your home test was negative, you had an urgent need to know if in fact you could be pregnant. In this case, the blood test would afford you tremendous peace of mind. This way, you would know beyond a shadow of a doubt that you are or are not pregnant.
If you took the home-urine test too early, then there is a chance you have gotten a false negative. In this case, yes, a blood test could find pregnancy when the home test did not. Haslots to do with timing, accuracy of testing method, reliability of the test (check expiration date) etc...
Whatever the case, I hope you are successful in whatever you do want to happen!
