Blood screening, Thyroid and Vaccine Titer Results

I took Red into my work for his annual physical and bloodwork a couple weeks ago. We stayed in the back though so we didn't freak the kitties out ;)

Dr. Callahan really liked him and said he was very handsome and a perfect weight (80 lbs). He sat so well for his blood draw - I held him while one of the other techs, Maria, drew from his front leg (cephalic vein). We had to get a lot of blood (15mL total) for all the testing I wanted to send out. I wanted full blood chemistries, CBC, heartworm, and also thyroid panel to MSU, as well as a vaccine antibody titer to MSU. He was such a good boy and stayed ever so still while he drew his blood =)

Got the results back:

Chemistries: AST (a liver enzyme) slightly high (77, ref 5-55), but it was high last year too. Since his other liver values are not elevated, the doctor is not too concerned. And maybe this is just normal for him? Everything else within normal limits.

Heartworm: Negative

MSU Thyroid: Low free T3 (2.8, ref 4.5-12.0), and everything else within normal limits. The endocrinologist interpretation states: "Circulating concentrations of thryoid hormones are generally normal and thyroid stimulating hormone is not elevated. The decrease of free T3 alone is unlikly to be of clinical significance. The negative autoantibody results further decrease the likelihood of lymphocytic thyroiditis in the thyroid glands of this dog. The results of this profile do not offer support for a differential diagnosis of hypothyroidism. Normal thyroid test results in a dog of this young age do not eliminate the possibility of hypothyroidism in the future."

Vaccine Antibody Titer:
Lepto (6 separate titers involved in lepto titering) = <50. Interpretation: "Leptospirosis titers are low and a booster vaccination should be considered if optimal disease protection is desired."
CPV (Parvo) = 160 (ref 80 or higher is protective)
CAV (Adenovirus) = 32 (ref 16 or higher is protective)
CDV (Distemper) = 32 (ref 32 or higher is protective)

So I will be boostering only the lepto and bordetella this year (there is no titer for bordetella). His rabies isn't due til 2011. I am happy I had all the blood testing done =) Now just waiting for September to roll around so I have have his echocardiogram rechecked...
