What can cause a false positive in an hpt?

A doctor has provided 1 answer

Time and technique: Testing too early, using dilute urine or not following the testing direction can produce a false negative result. If you have any concern, you may repeat the test with first morning urine, 4-5 days after a missed period and follow the directions carefully. You may also get a blood test through your doctor.
