false positive pregnancy test

A false positive pregnancy test result is a pregnancy hCG test that is positive when you are not pregnant and there are many possible reasons for this. What are the reasons for a false positive or false negative pregnancy test result?

A negative pregnancy test before a missed period could mean you tested too early; if your test is still negative after a missed period it often means you are not pregnant.

How often does this really happen? Is there really that large a margin
of error in commercial home pregnancy tests? Is it more likely to get a
false negative or a false positive? How sure can you really be when
looking at that little plastic stick?

Human error can cause both a false positive and false negative pregnancy test result. The most common human errors include not allowing enough urine to be absorbed onto the testing stick and reading the evaporation line as a positive test result.

A "Phantom hCG" is a positive blood pregnancy test without being pregnant. Patients with a phantom hCG will have a persistently and not significantly rising positive blood pregnancy test but the urine test is negative.

Besides a normal pregnancy there are other medical conditions that can give you a positive pregnancy test.

A positive blood pregnancy test without a pregnancy is also known as a 'false positive' test. There are many conditions which can give a phantom false positive hcg blood or urine pregnancy test.
