The leukocyte alkaline phosphatase (LAP / NAP) score has a possible scoring of 0 – 400. In general, a leukocyte alkaline phosphatase (LAP / NAP) score of 3+ or 4+ is considered normal, indicating that the neutrophils are mature and functioning normally.

中性粒细胞碱性磷酸酶积分{nap}采用偶氮偶联法，即成熟中性碱性磷酸酶在ph9.6左右的碱性环境中，能水解基质液中的磷酸萘酚钠底物，释放出萘酚，后者与重氮盐偶联，生成不溶性的有色沉淀，定位于细胞质酶活性所在之…

The neutrophil alkaline phosphatase (NAP) score is a valuable test for the diagnosis of myeloproliferative neoplasms, but it has still manually rated. Therefore, we developed a semi‐automatic rating method using Photoshop® and Image‐J, called ...

Neutrophil alkaline phosphatase (NAP) scores (reference range 20-150) have been reported to be low in isolated cases, but no comparison has been made of the diagnostic value of NAP, TALP, PEA and PLP in hypophosphatasia. We undertook such a comparison in six families with hypophosphatasia.

2005年1月14日 · The leukocyte alkaine phosphatase (LAP) score is often used in patients with an elevated WBC to differentiate a reactive process from chronic myeloge

2006年1月1日 · Neutrophil alkaline phosphatase (NAP) scores in patients with various types of respiratory tract infections. Bars indicate the mean value of each patient group. The 95% confi dence limits of the control group are 147–302.

中性粒细胞碱性磷酸酶(nap)是一种细胞内水解酶,主要存在于成熟中性粒细胞中,是粒细胞功能的标志酶之一[1],测定其活力的高低对于某些疾病的诊断、鉴别诊断和疗效观察有重要价值。

By adding up all activity grades, a total score is calculated (see example below). The possible scores range from 0 to 400. This value is called total NAP score. It normally ranges from 30 to 100. Each laboratory has to determine its own range of reference. A score below 20 is considered decreased and above 150 increased.

2007年12月1日 · In mature neutrophils granules contain alkaline phosphatase. In eosinophils no alkaline phosphatase activity is present. A considerable number of brown stained neutrophils can be indicative for a patient with infection (leukemoid reaction, A).

2018年1月1日 · Leukocyte alkalline phosphatase (LAP) (neutrophil alkaline phosphatase) is an enzyme present in normal neutrophils, but absent (or present at very low concentrations) in malignant neutrophils (e.g. in chronic myeloid leukaemia)
