成熟中性粒细胞碱性磷酸酶(以下简称ALP)组化试验已广泛应用于临床,特别对于某些血液病的鉴别诊断有一定参考价值。多数作者强调血片必须要新鲜,否则酶的活性就会降低,影响结果的判断。我们实验室经常收到基层单位寄来的骨髓片和血片,一般于取材后3～5天才做瑞氏与各种组化染色。因 Mature neutrophil alkaline phosphatase (hereinafter referred to as ALP) histochemistry has been widely used in clinical trials, especially for the differential diagnosis of certain blood diseases have some reference value. Most authors emphasize that blood films must be fresh, otherwise enzyme activity will be reduced, affecting the outcome of the judge. Our laboratory often receive the grass-roots units sent bone marrow slices and blood films, usually 3 to 5 days after the material to do Wright’s and a variety of staining. because
