Gavras等最近指出,人体白细胞总数可以自然地波动在3,200～7,500/mm~3之间,给鉴别诊断药物引起白细胞减少症或特发性白细胞减少症和属于正常范围的变化带来困难。由于上述波动情况已经见于正常人和良性家族性白细胞减少症,故波动比预测更为常见。不过,大多数都在早晨作白细胞计数,且检测次数太少,不能显示出一天内的变化,故正常波动常被忽视。基于上述情况,人们可以应用氢化考的松试验辅助鉴别诊断。健康人静脉法射200mg氢化考的松后,中
Recently, Gavras et al. Pointed out that the total number of human leukocytes fluctuates naturally between 3,200 and 7,500 / mm 3, making it difficult to differentiate the diagnosis drug from causing leukopenia or idiopathic leucopenia and falling within the normal range. Fluctuations are more common than predictions because the above mentioned fluctuations have been seen in normal subjects and in benign familial leukopenia. However, most of them make white blood cell counts in the morning, and the number of tests is too small to show the changes within a day. Therefore, the normal fluctuation is often neglected. Based on the above situation, one can apply hydrocortisone test to assist in the differential diagnosis. Healthy people intravenous injection of 200mg hydrogenated cortisone after
