Objective—To evaluate agreement between 2 portable triglyceride meters and a veterinary laboratory for measurement of blood triglyceride concentrations in dogs and evaluate effects of Hct and blood volume analyzed.

Sample Population—97 blood samples collected from 60 dogs.

Procedures—Triglyceride concentrations were measured in blood by use of 2 meters and compared with serum triglyceride concentrations determined by a veterinary laboratory. Within- and between-day precision, accuracy, and effects of blood volume and Hct were analyzed.

Results—Accuracy of both meters varied with triglyceride concentration, although both accurately delineated dogs with triglyceride concentrations < 180 mg/dL versus ≥ 180 mg/dL. One meter had results with excellent overall correlation with results of the standard laboratory method, with a concordance correlation coefficient of 0.94 and mean difference of 20.3 mg/dL. The other meter had a good overall concordance correlation coefficient of 0.86 with a higher absolute mean difference of −27.7 mg/dL. Results were only affected by blood volume; triglyceride concentrations determined via both meters were significantly lower when 7 μL of EDTA-anticoagulated blood was used, compared with larger volumes.

Conclusions and Clinical Relevance—1 meter had greater accuracy in the range of 140 to 400 mg/dL and was therefore well suited to detect hypertriglyceridemia. The other meter was accurate with triglyceride values < 140 mg/dL and yielded results similar to those of the veterinary laboratory in the range of 140 to 400 mg/dL, therefore being suitable for determination of triglyceride concentrations in nonfed dogs and dogs with mildly high concentrations.

Objective—To compare serum triglyceride concentrations obtained after food had been withheld (ie, fasting concentrations) in dogs with epilepsy that had been treated long term (t 3 months) with phenobarbital or with phenobarbital and potassium bromide with concentrations in healthy control dogs.

Design—Cross-sectional study.

Animals—57 epileptic dogs that had been treated with phenobarbital (n = 28) or with phenobarbital and bromide (29) and 57 healthy, untreated control dogs matched on the basis of age, breed, sex, neuter status, and body condition score.

Procedures—Blood samples were collected after food had been withheld for at least 12 hours, and serum biochemical and lipid concentrations were determined. Oral fat tolerance tests were performed in 15 control dogs and 9 dogs with epilepsy treated with phenobarbital alone.

Results—19 of the 57 (33%) epileptic dogs had fasting serum triglyceride concentrations greater than the upper reference limit. Nine (16%) dogs had a history of pancreatitis, and 5 of the 9 had high fasting serum triglyceride concentrations at the time of the study. A significant relationship was found between body condition score and fasting serum triglyceride concentration in all dogs, but serum triglyceride concentration was not significantly associated with phenobarbital dosage or serum phenobarbital concentration.

Conclusions and Clinical Relevance—Results suggested that dogs treated long term with phenobarbital or with phenobarbital and bromide may develop hypertriglyceridemia. Fasting serum triglyceride concentration should be periodically monitored in dogs treated with phenobarbital because hypertriglyceridemia is a risk factor for pancreatitis.
