Did you do any testing for autoimmune disease? Slide agglutination test or Coomb's test?
he's really big on ruling out one thing at a time, so he has not done those yet. i asked today about screening for autoimmune, and he said that would be the next step.
so far we've done the following things:
first we did regular CBC screening, HW test w/ the associated ehrlichia and whatever other things they now do in that one HW blood draw, fecal and urinalysis
after we got the results, we put him on iron, then a followup CBC after some iron supplementation
then ultrasound because the xrays showed abnormalities
ultrasound resulted in biopsies and tests for degenerative or regenerative anemia (as of friday, we learned that his anemia is regenerative, so his body is trying to keep up, causing some heart and spleen enlargement)
today, we took blood for a more specific tick panel, which will screen for babesia, among other things
and we do doxy and look for signs of improvement. so that's where we are at. if the tick panel is negative, he said he wants to stick with the doxy for a week and look for signs of improvement, because a negative tick panel doesn't necessarily mean he does not have something tickborne, such as babesia or rocky mountain spotted fever, etc.
if the doxy does nothing at all and a followup CBC shows no improvement in anemia, then we'll start testing for autoimmune issues.
in the meantime, he says, if we see any signs that tucker is starting to deteriorate, we should be calling him immediately to speed things along.
one thing that concerns me: he asked us to come in on monday for another blood draw for B12/folates test. which is fine, except we've had no abnormal stools, no temperament issues, no vomiting, no dry coat, no eating inappropriate items. i really doubt PICA or SIBO, because his symptoms just don't seem to be consistent. but they are pretty consistent with tickborne or IMHA/AIHA of some sort, from what i can tell.
i dunno. this really does suck.
