%%tab-血小板压积
  中文名称:血小板压积 异名:[血小板比积]\\
  英文名称:[plateletcrit] \\
__项目介绍 :__\\
  血小板比积与血小板和 MPV呈正相关,所以血小板比积的增减随血小板和MPV而增减。

%%tab-临床意义
增高:血小板增多症、慢性粒细胞性白血病(早期升高)。
/%
%%tab-参考范围
血细胞自动分析仪:男性:0.108%~0.272%,女性:0.114%~0.282%。

%%tab-方法学评价
1.血小板计数在 1天内不同时间可相差6%~10%,表现为清晨较低,午后略高;春季较低,冬季略高。 \\
2.平原地区居民较低,高原地区较高;运动时偏高,休息后恢复;月经前降低,月经后升高。 \\
3.静脉血比手指血偏高。\\
4.由于影响血小板计数的因素较多,一次检验较难获得准确结果,应反复计数几次,再确定有无改变。\\
5.有很多药物可导致血小板升高或降低,如肾上腺素、糖皮质激素等使血小板升高;苯妥英钠、格鲁米特、保泰松、氯丙嗪、氯霉素、环磷酰胺、长春新碱、洋地黄毒苷、磺胺类、螺内酯、可待因、他巴唑、利尿酸、氯苯那敏、链霉素、多西环素等能使血小板减少。\\

%%tab-标本采集和运送要求
标本采集:除卧床病人外,一般采取坐位。成人一般从肘静脉取血,在采血前应静坐5min。使用止血带的时间不超过1min。EDTA-K2抗凝血(浓度为150-180g/L),静脉抽血2ml,立即颠倒混匀,防止凝固。\\

标本运送:试管上粘贴唯一标识号,该标识号可以是条形码,也可以是申请单的联号。如果是条形码包含患者姓名、检验目的、标本类型、标本采集日期等信息。如需将标本从原始采血管中转移到新的采血管时,新的采血管要有与原采血管信息一致的标识。\\
