A few years ago my boyfriend's mom was daignosed with hepatitis C. Because of this, my boyfriend was tested by taking several vials of blood to make sure he didn't have it. He said he was tested for a bunch of things, but he's not sure what for. I'm not sure what to make of this, I don't know if they just tested his potassium/electrolyte levels and all that kind of stuff that they sometimes do in blood check-ups or if they tested for other diseases. Does anyone know anything about this kind of testing? Do you think they would have tested for HIV?
