What Causes Positive Results With Pregnancy Test Kits And Negative In Clinic?

default
Posted on Wed, 6 Apr 2016
Question: So I have taken multiple different at home pregnancy tests and all have come back positive but when I went to a clinic to have them test it was negative I was told it could just been too early and theirs just isn't sensitive enough. I need answers because I would like to tell family.

Brief Answer:
you can do the blood test

Detailed Answer:
Hello,

urine tests are good as screening tests but no as accurate as the blood test. The blood tests measures the levels of beta-chorionic gonadotropin (beta-hCG) while the urine test can only detect whether it's present or not regardless of its levels. During pregnancy the levels of beta-hCG rise according to the age of pregnancy, so it's a more accurate method.

An ultrasound scan may detect the sac.

The aforementioned methods are much better than the home kit, so you'd better do them to be sure.

Kind Regards!
