Blood Tests Offer a Diagnosis

Catcher returned to the vet today for a recheck of his glucose levels.

At 1:00pm BG: 139 (yay!)

Our plan: to recheck a preanesthetic profile on Thursday.

and here is where it begins to get interesting...

Results are in from the Tick Panel, TLI, and Immune panels...

Lyme - Positive 1:400*
Antinuclear Antibody (ANA): Positive 1:25
Rheumatoid factor: Negative
Ehrlichia Canis: Negative
Rocky Mountain Spotted Fever: Negative
Trypsin-Like Immunoreactivity: 2.1**
Coombs Test: Negative
Platelet Count: 238 (within normal limits of 164-510 thous/uL)

* Now remember that Catcher had an all around negative 4DX test in February. We decided to rerun a 3DX and see what it said. Negative all around. Hmmm. Notes from lab report: "A positive titer indicates exposure to the Borrelia Burgdorferi or similar antigen but does not confirm the presence of the disease. Titers may be affected by vaccination or disease." So we decided it was a false positive due to vaccine history.

** Reference range for TLI is 5-35ug/L. Catcher read 2.1. Anything <2.5 is consistent with Exocrine Pancreatic Insufficiency.

(There is also a note regarding the ANA about age or inflammatory disease but I can't decipher it)
