Accuracy of Blood Test?

Question

How accurate are blood tests? Has anyone out there ever taken 7 or more pregnancy tests then have the blood test come back negative???

Answer 1

Blood tests are supposed to be 100% right. Blood cannot lie, as long as it isn't too early. But blood tests can be done earlier then home tests. Are you saying you got positive home tests, and a positive blood test? If so, i'd demand a re-test. If they were all neg, you're probably not pregnant.

Answer 2

i had blood tests done until i was 5 months pregnant, and they all came back negitive. by the time i got a positive result, i could feel the baby moving and was showing the tell tale signs of a bump....
if the test you have done at home are positive i'd go with them.... give it another few weeks and by then hopefully a blood test will be positive.

Answer 3

Morning after pill ought to effect it, however the greater probable answer is which you ovulated later than you theory you will possibly have and hence, you're no longer technically late. Worst case scenario, you ought to 'conceive' 7 days after intercourse and in case you have been ovulating top then, and conceived top then, even the worst being pregnant attempt might inform you definite withing 14 days. So 3 weeks after having intercourse if the exams say NO, it relatively is NO. No concerns. the difficulty is which you in basic terms ovulated later than general, so which you are going to have your era later. No concerns, sweetie, you're no longer pregnant (except, of direction you had intercourse unprotected back AFTER that).

Answer 5

It is very possible that you may have been at the very earliest stage of pregnancy and then miscarried .
