Postive blood test with a negative biopsy is not at all unusual even among people who keep eating gluten. The person taking the biopsy samples might miss the damaged areas or the lab might not be experienced reading celiac slides. In addition, you should not have gone gluten-free before the biopsy because, yes, six months is indeed enough time for the damage to heal. The final question is what criteria does your lab and doctor use to establish celiac? Some won't call it celiac unles your villi are completely flattened (yours wouldn't be because you went mostly gluten-free) but more and more experts are saying it should be called celiac with MUCH less damage.
Depending on which blood tests you had, these rarely give false positives. What blood tests were positive? What symptoms were you having? Did they resolve on the gluten-free diet? Did you feel better on the diet? These are some other questions you have to ask yourself.
