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?
The emergency room pregnancy test is often referred to as a
point-of-care (POC) urine test. POC tests are relatively accurate, but
even low numbers of false negatives are important considering the large
number of overall tests run each year.
A false negative pregnancy test is a pregnancy hCG test which is negative when in fact you are pregnant. You are pregnant but you have a negative pregnancy test.
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.
Most pregnancy tests are not positive until after you miss your period.
A positive pregnancy test usually means that you are pregnant. There are
only a very few circumstances in which a false positive pregnancy test means
that you are not pregnant .
