Abstract:
Objective Comparison the corrective effect of plasma exchange method and formula method for chylemia on hematology analysis.Methods A total of 10 samples without hemolysis,jaundice and lipemia were set as control group,each sample was divided into 4 parts,then 5,10,20 and 40 μl lipid emulsion was added.Each chylous samples was treated by plasma exchange method for two times,and routine blood test was reanalyzed with hematology analyzer.The comparisons before and after the exchange was made,while the test results on each exchange were analyzed.For another part,the HGB of chylous plasma was tested,the value was substituted into HGBcorrected value =HGBbefore correction-(HGBchylous plasma-HGBchylous plasma ×HCTbefore correction).Results The chylemia could lead significant increase of HGB,MCH and MCHC (P＜0.05).After plasma exchanging for two times,the three parameters returned to normal and the count of WBC,RBC and PLT decline slightly with no significance.There were no differences between plasma exchange method and formula calibration method.Conclusion Plasma exchange method and formula calibration method could significantly reduce the impact of chylemia on routine blood analysis,which facilitate the clinical work with correct analysis of routine blood test.
