Abstract:

Objective To evaluate the application of AVE-562 automated feces analyzer. Methods A total of 3 028 feces specimens were determined by manual microscopy and AVE-562 automated feces analyzer. The results of manual microscopy were as gold standard. Occult blood（OB） test results determined automatically by AVE-562 were compared with those of manual microscopy by OB test strip of Kangzhu Company. The sensitivity,specificity and accuracy were calculated. Results The coincidence rate was 97.85% for OB test of AVE-562 and OB test strip（kappa=0.918）. The sensitivities of red blood cell（RBC）,white blood cell（WBC）,parasite and fat globule were 86.05%,80.95%,72.00% and 91.89%,respectively. The specificities of RBC,WBC,parasite and fat globule were 99.63%,99.80%,99.73% and 99.86%,respectively. The accuracies of RBC,WBC,parasite and fat globule were 99.44%,99.54%,99.50% and 99.67%,respectively. The kappa values of RBC,WBC,parasite and fat globule were 0.810,0.827,0.703 and 0.930,respectively. Conclusions The results of RBC,WBC and other indices by AVE-562 automated feces analyzer and manual microscopy have good consistency. It is easy to operate for AVE-562 automated feces analyzer with application value.
