Can anything else trigger a positive pregnancy test?

What causes hCG levels to rise if not pregnant?

Can your body produce hCG if you are not pregnant?
HCG is produced in very minimal quantities in non-pregnant women and men and does not appear to play an appreciable role in body functions. Higher-than-normal levels of hCG may also be present in certain types of cancers in males and non-pregnant females.
What should you not do before pregnancy test?
Don’t drink too much water, or any liquid, before taking a pregnancy test. Excess fluids can impact the accuracy of the test results, so if your urine is diluted or pale yellow, hold off on taking a test. Diluted urine tends to also have diluted hCG levels which can skew the test results.

Why would hCG levels be high?
If you are pregnant, very high levels of hCG can mean a multiple pregnancy (such as twins or triplets). It can also mean a molar pregnancy or Down syndrome. You may also be further along in an early pregnancy than you thought, based on your last menstrual period.
What causes phantom hCG?
The reason for a phantom hCG is that some individuals react falsely positive to some substrate in the blood hCG test and thus will display a consistently low positive blood pregnancy test even though they are not pregnant, but their urine test will be negative.
