We had ours at CVS. $38 flat rate. We both knew we had positive antibodies because we had donated blood with Oneblood and they test for free, but never could get the correct paperwork to use that test. I have heard of some using the RedCross antibody test given during donation and that one having the proper results. ie, name, dob, test given and date, lab providing the test and igg and igm results.
