The clinical use of the WBC differential was investigated before and after it was made available on demand. The results indicate that no consistent policy existed in our hospital for the ordering of a differential. When differentials were made available on demand, the number of differentials did not increase compared with earlier periods. The demand for differentials may have been caused more by the denial of a physician's prerogative to order a differential rather than by its requirement for patient care.
在按需提供白细胞分类计数之前和之后，对其临床应用进行了调查。结果表明，我院在开具白细胞分类计数检查单方面没有统一的政策。当按需提供白细胞分类计数检查时，与早期相比，检查单数量并未增加。对白细胞分类计数检查的需求，可能更多是由于医生开具此类检查单的特权被拒绝，而非患者护理的需要。
