Are you pregnant? Or having some sort of issue?
If you are pregnant, from my understanding... the thing with HCG isn't the first number..... it's the difference between the 2 numbers 48 hours apart. So, if your HCG is 0.12 today and you are pregnant, then your HGC in 48 hours would need to DOUBLE or be 0.24.
Having said that.... 0.12 is pretty low. Are you sure you got the # right? People who are not pregnant can have an HCG of 0.00 - 5.00.
So I'm not sure why you are having this test or what the information will tell you - this is something that only your Dr can provide information on your specific situation. Good Luck.
