Description

一种血液分析仪及血红蛋白检测方法 技术领域
本申请涉及医疗检测领域,尤其是血液蛋白检测领域,涉及但不限于一种血液分析仪及血红蛋白检测方法。
背景技术
人的血液中含有红细胞、白细胞、血小板等各种细胞,其中在红细胞中包括有血红蛋白。血红蛋白(Hemoglobin,HGB,或Haemoglobin,Hb)是红细胞内运输氧的特殊蛋白质,是使血液呈红色的蛋白,由珠蛋白和血红素组成,其珠蛋白部分是由两对不同的珠蛋白链组成的四聚体。血红蛋白与红细胞的使用价值近似,血红蛋白的升高和降低在临床医学中具有重大的意义,尤其通过对血红蛋白含量的检测来反应人的贫血程度。
众所周知,血红蛋白的测量方法一般为比色法。比色法的测量原理是待测试样本的溶液浓度的不同,对应的溶液颜色不同。一般溶液浓度越高,即血红蛋白含量越高,则溶液的颜色越深,反之溶液的浓度越低即血红蛋白的含量越低,则溶液颜色越浅。其中,待测试样本的溶液颜色的深浅直接影响了待测试样本对光线的吸收程度,即待测试样本的溶液颜色越深,吸收的光线越多,透过的光线越少,反之,溶液颜色越浅吸收的光线越少,透过的光线越多。因此,通过测量透过比色池光线的强弱,可以测量出待测试样本的溶液浓度。
但是,待测试样本存在异常时,例如待测试样本为乳糜血样本、高值白细胞(White Blood Cell,WBC)或胆红素等均会导致HGB假性偏高。例如,由于乳糜颗粒的存在,导致光线部分被散射,透过的光线减少,造成通过比色法获得的血红蛋白浓度测试值假性偏高。目前,临床通常采用人工方式来判断待测试样本是否为乳糜血。并在人工判断待测试样本为乳糜血时,采用血浆置换实验去除乳糜,然后对去除乳糜后的待测试样本进行测试,以获得准确的血红蛋白浓度测试值,此方法费时费力,对操作人员的技能要求较高。
由于上述异常情况的存在,目前的血红蛋白进行测试的仪器不能区分待测试样本是否存在异常,导致对血红蛋白进行测试的测试结果的准确率 较低,造成血红蛋白进行测试的仪器的智能化程度较低。
发明内容
有鉴于此,本申请实施例期望提供一种血液分析仪及血红蛋白检测方法,其解决了目前对血红蛋白进行测试的准确率较低的问题,实现了自动化判断待测试样本是否存在异常,并根据判断结果确定后续的自动处理方式,保证了血红蛋白浓度测试结果的准确性。
