Question

Positive Hpt but negative blood test?

I had a positive frer Hpt but my quantitative blood test only detected 3miu/ml that day.

I’m very confused. I showed the hpt line to my OB and she seen it too, so she ordered the first blood draw. It came back as only 3miu/ml!!! I have another draw coming up on Monday. Since the blood test yesterday, my HPTs have gotten darker. Anyone have experience with a similar situation?

That’s interesting, you’ll have to keep us updated! I’ve never heard of that. I hope that your future tests turn out higher numbers!
One thing my endo told me when I got a faint positive hpt (I was not pregnant) recently was that sometimes if your TSH (I think that’s the hormone she mentioned) is high you can get some cross reactivity and a positive on a test. Maybe if the numbers don’t go up she can have blood work done to check your thyroid out.
Hope all is well! Good luck to you!
