Comparison of whole blood and plasma colloid osmotic pressure in healthy cats

OBJECTIVE: To establish reference intervals for whole blood and plasma colloid osmotic pressure (COP) in healthy cats between the ages of 1 and 10 years using a cage‐side colloid osmometer. DESIGN: Prospective, observational study. SETTINGS: University veterinary teaching hospital. ANIMALS: Sixty‐th...

Description
Summary:OBJECTIVE: To establish reference intervals for whole blood and plasma colloid osmotic pressure (COP) in healthy cats between the ages of 1 and 10 years using a cage‐side colloid osmometer. DESIGN: Prospective, observational study. SETTINGS: University veterinary teaching hospital. ANIMALS: Sixty‐three healthy cats. INTERVENTIONS: Phlebotomy. MEASUREMENTS AND MAIN RESULTS: Whole blood COP mean was 24.4 (±2.78) mmHg and plasma COP mean was 24.3 (±2.59) mmHg. Reference interval for our study population of feline whole blood COP was 18.9 to 30.4 mmHg, and for our study population of feline plasma COP was 18.3 to 30.8 mmHg. Difference of paired whole blood COP and plasma COP was +0.23 ± 1.68 mmHg (P = 0.32). There was no significant difference when comparing COP from neutered male and neutered female cats. Total protein and albumin were significantly correlated with whole blood COP (total protein to whole blood COP P < 0.0001, r = 0.53; albumin to whole blood COP P
