RESUMO
The effects of various types of anticoagulants on plasma biochemistry were studied in man and various animals, but limited information is existing for ostrich plasma biochemistry. Ten clinically healthy ostrich were blood sampled in different tubes containing each anticoagulant and plain tube for harvesting plasma and serum. The concentrations of glucose, cholesterol, uric acid, creatinine, total protein, albumin, calcium, inorganic phosphorus, and magnesium and the activity of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and gamma glutamyl transferase (GGT) were measured. The concentrations of glucose, uric acid, total protein, and calcium were significantly lower in citrated plasma than that of serum. For dilution corrected citrated plasma significant differences were only seen for the concentration of uric acid. Most parameters did not show any differences, but significant increase were seen for glucose, total protein, albumin, and phosphorus concentrations when heparin was used as an anticoagulant.
