The MAXM is a compact blood count and differential analyzer that appeals to both the space-limited, full-service laboratory and the large outpatient practice. The authors compared the performance of the Coulter MAXM to the larger Coulter STKS. Linearity and precision studies were comparable to the STKS. MAXM leukocyte differentials were closely correlated with STKS and manual readings, being excellent in the neutrophil, lymphocyte, and eosinophil categories but poorer on monocyte counts. Basophil counts did not correlate with STKS or manual counts. Analyzer suspect flagging was similar in both machines, with the MAXM exhibiting slightly reduced sensitivity and greater specificity. MAXM processing of a single sample requires twice the time. The MAXM functions well for a large office practice and as a backup for large medical laboratories but, because of its hands-on requirements and lack of speed, cannot replace the larger, more automated analyzers.
MAXM是一款紧凑型血细胞计数及分类分析仪，对空间有限的全方位服务实验室和大型门诊诊所都有吸引力。作者将库尔特MAXM与更大的库尔特STKS的性能进行了比较。线性和精密度研究结果与STKS相当。MAXM白细胞分类结果与STKS及手工读数密切相关，在中性粒细胞、淋巴细胞和嗜酸性粒细胞类别中表现出色，但单核细胞计数结果较差。嗜碱性粒细胞计数与STKS或手工计数结果不相关。两台仪器的分析仪可疑标记情况相似，MAXM的灵敏度略有降低但特异性更高。MAXM处理单个样本所需时间是原来的两倍。MAXM在大型诊所运行良好，可作为大型医学实验室的备用设备，但由于其需要人工操作且速度较慢，无法取代更大、自动化程度更高的分析仪。
