OB-GYN (Obstetrician-Gynecologist) Questions Pregnancy Tests

Can at-home pregnancy tests be wrong?

My period was late so I took multiple (3) at-home pregnancy tests, which all came back positive. But then, I took a pregnancy blood test, which came back negative. How is this possible? Can at-home tests be wrong?

The blood test can measure the hormone level in the blood and are more accurate than a home test. The best thing to do is to do another test. Incorrect test usage, previous abortions and miscarriages, and some medication can give false-positive pregnancy test result. Thank you.
Yes.
The blood test is the most accurate. I have seen this before. However, 3 positive urine tests is a little unusual.
Certain over-the-counter pregnancy tests you use could be defective. When you are in doubt, a blood test is an accurate alternative.
Take care!
