AGUDELO VASQUEZ, Manuela J; ORTEGA BOTERO, Vladimir  and  OLIVERA-ANGEL, Martha. EFFECT OF CANINE BLOOD SAMPLES HEMOLYSIS IN THE RESULT OF SOME ENZYME ANALYSES. Biosalud [online]. 2014, vol.13, n.1, pp.21-29. ISSN 1657-9550.

Background: Hemolysis is the destruction process of red blood cells, which involves the release of the intra-erythrocytic content into the plasma altering its composition. The main intra-erythrocytic molecule is hemoglobin, that has a characteristic absorption spectrum of the heme group, with a peak at 405 nm and several peaks between 500-600 nm, and produces a reddish color in plasma, proportional to the hemoglobin released (Figure 1). Hemolysis is usually defined as the appearance of 0.3 g/l of hemoglobin in plasma which is considered the minimum visually detectable concentration. Hemolysis in the samples to be analyzed can interfere with the results and therefore, if it is a bad test taking it should be a cause for rejection. The Veterinary Clinic Laboratory does not have a study of the behavior of different analytes, so the importance of the present study is based on determining the effects of hemolysis in canine serum on the reading of some analytes that are frequently requested in the laboratory. Objective: To describe the range of variation of the results of some analytes with respect to the amount of hemolysis in a sample. Method: The blood count was performed in the Abacus Junior Vet® equipment; the Turbidimetry method in the BioSystems A15 for Clinical Chemistry was used for the analytes. Hemolysis was induced mechanically. Results: Analysis of variance with a completely randomized design was used and statistical differences at p < 0.05 levels were determined. Interferograms which allow defining the degree of interference, if any, were carried out. Conclusion: Hemolysis in canine serum either mild (0.10 - 1.00 g/l) or severe (2.51 to 4.5 g/l) interferes with the reading of analytes ALT (Alanine Aminotransferase), Creatinine and Urea.
