    Default Can an OPK detect HCG?

    As the title says... I'm 8dpo. I know this is definite because I had an internal done week and my GYN said I was. I just did an OPK because I heard its possible and it came up with a very strong line. I kind of really need to know if I am because I'm having surgery over the next few weeks. I really really would like to be! So does anyone know? Im buying a test tonight but I'm just so impatient lol.
    Here's the pic.

    No, they can't. They detect Lutenizing Hormone (LH), which is not the same as hCG (the hormone that is released by the ovaries when implantation takes place. Although when you are pregnant you release LH, you also do for other reasons - so although an OPK will turn positive when you are pregnant, it can also turn positive for a multitude of other reasons - and is therefore not a diagnostic tool that should be used for pregnancy.

    The last comment is not quite right. Opk's DO detect hcg.
    Hcg and LH are similar compounds. Basically hcg is the same as LH but with an extra 'bit'. So the opk detects hcg as it appears the same as LH.
    On the other hand, an hpt will NOT detect LH, as an hpt detects that extra 'bit' that ONLY hcg has.

    But unfortunately, only an hpt will give you the answer
