What are the chances of a false positive pregnancy test?

Can a positive pregnancy test be wrong?
It’s possible to have a positive pregnancy test even if you aren’t technically pregnant. This is called a false positive. It’s sometimes caused by a chemical pregnancy. A chemical pregnancy occurs if a fertilized egg, known as the embryo, is unable to implant, or grow, very early on.
What causes hCG levels to rise if not pregnant?

Can sperm cause a false positive pregnancy test?
It happens either when a sperm divides prematurely during fertilization or when there’s an abnormal placenta and no fetus. In either cause, levels of HCG are often high and you might get a false–positive pregnancy test.
Does a faint line mean pregnant?
If you take a home pregnancy test and the results reveal a faint positive line, there’s a strong possibility that you’re pregnant. In these instances, a faint positive can be caused by low levels of the pregnancy hormone human chorionic gonadotropin (hCG). As soon as you become pregnant, your body begins producing hCG.
What is borderline pregnancy?
A borderline result is generated by some assays when the hCG level is between 5 and 25 mIU/mL. Samples reported as borderline are considered indeterminate, and clinicians should request a repeat test within 48 to 72 hours or obtain a quantitative serum hCG.
What are the very early signs of pregnancy?
The most common early signs and symptoms of pregnancy might include:
- Missed period. If you’re in your childbearing years and a week or more has passed without the start of an expected menstrual cycle, you might be pregnant.

How soon does hCG show up in urine?
hCG levels can usually be detected in the urine about 10 days after conception. If you take a urine pregnancy test fewer than 10 days after conception, the at-home tests might give a “false negative” response. This means it will show that you are not pregnant when you actually are.
