I've been using Pan am for testing, but now after hearing people get false positives, i'm worried about that, as well as worried about false negatives. So my question is this - i know WSU is a good lab to get the most accurate results, but i was wondering about BioTracking ? Do they use the same type of testing as WSU ? Anybody know if i could use BioTracking with comfort ? I'd like to give them my business ( as well as get preg. tests done ), and in turn they also appear to be cheaper. Thanks !
