Urine test vs. blood test

I took an at home test on Sat which came up positive but yesterday I went to a clinic and they did a urine test which cam up negative. I don't know which to go by since they were both urine test either one could be wrong. I made an app. with an OBGYN but it is not till the 13th of Aug. Should I ask for a blood test sooner than that? Confused.

Re: Urine test vs. blood test

  • HPT are generally more sensitive then the ones they use in clinics/doctor's offices.  Try taking a few more HPT. If they come up positive, you have your answer.

  • At home tests are generally very sensitive, and the doc's tests can actually be less so.  However, I'd expect that two days later your hormones would have increased to the point where a doc's test would show a positive.

    Have you taken any more at-home tests?  What do they show?

  • The same thing happened to me, but my negative test was at the OBGYN. My doctor took blood to get a definitive answer. I would take another HPT tomorrow with first morning urine.
  • I took a total of 4 HPT's, just to make sure.  The first two were the regular one-line/two-line tests, and DH didn't believe me that even a very very faint second line was positive, so he went out and bought a two pack of the ClearBlue Easy digitals.  I did one, it was positive, a few days later I got bored, so I did the other one, and yep, positive.

  • I would request a blood test if that is the case.  If your HPT is saying positive... than more than likely - you are pregnant.  Try taking another HPT first to be sure.  If it comes up positive again - the clinic's urine test had to have been defective.

     Good Luck!

  • Thanks so much, this really helps.
  • Was the clinic/doc test taken with dilute urine?  Not only are they frequently less sensitive than early home tests, but the amount of hcg this early in pregnancy (you aren't even 4 weeks yet) is so low that if your urine isn't concentrated enough, you'll get a negative.

    A blood test will likely put your mind at ease, and the worst they can do is say no.

  • When I first went to the doc they did a urine test which came back negative. I asked for a blood test right then and there and it was positive.  I would get the blood test done asap.
  • More tests are the only answer.. I put this in a previous post, but I'll repeat it here. I had several positive HPT, 2 faint liners and 1 digital, then a negative blood test. It was a CP..  just wait and test again tomorrow or ask for a blood test. I hope everything works out OK.
