Yes, this happened to me with my first pregnancy. I apparently didn't produce enough HCG for the HPT to pick it up, but the BT done in the DR office did.

A serum hCG will be positive for pregnancy at 25mIU/ml, the urine test, although just as accurate needs a stronger concentration of 50mIU/ml to 100mIU/ml depending on the brand - this means the serum (blood) test will test positive 2 to 3 days sooner than urine.

Could a yeast infection cause a pregnancy test to be negative even if you are pregnant?

No. The only thing that will cause a negative pregnancy test is no HCG in your Urine. A pregnancy test will only become positive when HCG has been detected in your Urine. If it does not become positive then no HCG has been detected. Test in a week and if it is still negative then see your doctor for a blood test or confirmation.

Why would a urine test come out positive before taking and negative after taking antibiotics for a bladder infection when you are on Mircette Birth Control and started your period a week ago?

Bladder infections can spread into your kidneys and then into the blodd stream so they were probably checking to see how far it had progressed. I dont know if you understood my question, i know why they took the urine and blood samples. But i dont understand why a pregnancy urine test would say positive 3 times, pregnancy blood test say negative twice, and then another urine test done 6 hrs after being administered antibiotics come out negative. What was with that first urine test saying positive?

Is it possible to get a positive result with first morning urine but get a negative result with urine after that?

Yes, the urine in the morning has high quanties of the hormones needed to produce a positive pregnancy test. If you are very early on in your pregnancy, it could show up negative later in the day, either wait a bit longer - a few more weeks, before taking another test, or even better go to the doctors and he will do a blood test! Yes, that is why the instructions tell you to test with the first urine you pass in the morning. The test is 99% accurate if positive with the first urine of the day.


Can you have 3 positive prgenancy tests but not have it show in a blood test?

No. A blood pregnancy test is far more accurate than the over the counter urine tests. The OTC tests measure the amout of a specific hormone in your urine. This level can be sporatic and sometimes give a false positive or a false negative.
