Study on the clinical application of optical microscope in the coagulation pre-test quality control

Objective To investigate the clinical value of the optical microscope on the quality control of the coagulation specimen microscopic examination before the coagulation test.Methods 92 patients with coagulation specimens agglutination occurs which taken were selected as the experimental group,92 patients re-blood microscopy to ensure that no agglutination phenomenon was set to control,observed differences in coagulation indexes of the two groups.Results The PT,APTT,TT and Fg were statistically significant(P ＜ 0.05) between experimental group and control group by the q test.Different agglutination specimens group in the experimental group by analysis of variance,PT,APTT.TT and Fg were statistically significant(P ＜ 0.05) between groups comparison of the q test analysis,PT,APTT,TT and Fg were significant differences (P ＜ 0.05).With the aggravation of blood specimens agglutination,PT,APTT and TT time extension and Fg concentration reduce more serious.Conclusion Optical microscope before the introduction of clotting function tests experimental quality control a large extent,to enhance the accuracy of laboratory coagulation test results,clinical diagnosis and preoperative preparation has important clinical value.
