Abstract:
Objective To investigate the reference intervals of mean corpuscular volume (MCV) ,mean corpuscular hemoglo‐bin(MCH) and mean corpuscular hemoglobin concentration (MCHC) examined by the MindrayBC‐6800 hematological analyzer to establish the reference intervals suitable for our laboratory .Methods According to the method recommended by the NCCLS C28‐A3 ,600 healthy adult individuals were selected as the reference individuals .MCV ,MCH and MCHC levels were determined by the MindrayBC‐6800 hematological analyzer for constructing the reference intervals ;other 150 healthy persons undergoing the physical examination were selected and their MCH ,MCV and MCHC detection results were collected for verifying the established reference intervals .Results The detection results of MCV ,MCH and MCHC in healthy adults showed a normal distribution ,MCV had sta‐tistical difference among different age periods (P<0 .05);the reference intervals :82 .278 -94 .242 fL for young adults ,83 .032-94 .608 fL for the middle‐aged persons and 83 .137-96 .343 fL for the elderly .MCH had statistical differences between different se‐xes and among different age periods ;the reference intervals :27 .785-32 .415 pg for male young adults ,28 .324-32 .456 pg for male middle‐aged persons and 28 .274-32 .966 pg for male elderly ;27 .367-31 .973 pg for female young adults ,27 .445-32 .215 pg for female middle‐aged persons and 27 .532 -32 .468 pg for female elderly .MCHC had statistical difference between different sexes (P<0 .05) ;the reference intervals :328 .611-352 .810 g/L for male and 323 .771-348 .750 g/L for female .In 150 individuals un‐dergoing the physical examination ,the proportion of individuals locating at the outside of reference interval was less than 10 .0% , therefore the newly established intervals were suitable for this laboratory .Conclusion The sex difference or/and age differences of MCV ,MCH and MCHC exist among adult populations .So the reference intervals are respectively established according to the prac‐tical situation ,which are suitable for this laboratory by verification .
