Pregnancy blood test sensitivity 25 mg International Units/mL but, I was told it was negative. I've read on other sites that that blood test 5,10,25, mI/mL is postive. I can't figure it out. Please help me understand

So, the blood tests are sensitive. It depends on the type of testing in the lab. Most use less than 5 mIU/ml as the lower area. If you have an HCG less than that, typically it is considered negative.
