Blood cellular and biochemical studies in canine dirofilariasis.

Haematological studies in heartworm-infected dogs revealed low haemoglobin concentration, increased erythrocyte sedimentation rate and a marked increase in lymphocyte percentage. Biochemical analysis of serum of dogs infected with heartworm showed increases in serum total bilirubin, serum globulin, chloride, phosphorus, serum glutamic oxaloacetic transaminase and serum glutamic pyruvic transaminase values and a decrease in albumin content.
