【摘要】目的:探讨临床贫血诊断中血液检验的应用价值。方法:以47例地中海贫血患者、53例缺铁性贫血患者及40例健康体检者为研究对象。对比分析三组患者血液中RBC、MCH、Hb、MCV和RDW五项观察指标差异,计算血液检验方法应用于不同类型贫血诊断中检验灵敏度、特异性和约登指数,对各项数据结果予进行对比分析。结果:三组各项血液检测观察指标差异明显(P<0.05);地中海贫血组MCH和Hb水平明显高于缺铁性贫血组(P<0.05),明显低于对照组(P<0.05),而RDW指标水平明显低于缺铁性贫血组(P<0.05);缺铁性贫血组RDW水平明显高于其它两组(P<0.05)。结论:临床诊断贫血时血液检验可取得良好的诊断效果,但其误诊率也较高,辅以其它诊断方式可取得更为确切的鉴别诊断结果。

Abstract:Objective To explore the application value of blood test in the diagnosis of clinical anemia.Methods 47 cases of patients with the Mediterranean anemia,53 patients with iron deficiency anemia and 40 cases of healthy subjects were studied. Compared and analyzed the difference in three groups of patients with blood RBC, MCH, Hb, MCV and RDW five observation indexs, calculated the blood test method application in different types of Anemia Diagnosis mid-term test sensitivity, specificity and Youden′s finger. Results The difference of all the blood test observation indexs in the three groups was significant (P<0.05); MCH and Hb level in mediterranean anemia group was significantly higher than that of iron deficiency anemia group(P<0.05) ,was significantly lower than that in the contrast group(P<0.05), and RDW levels was significantly lower than that of ischemic anemia group(P<0.05);ischemic anemia group of RDW levels were significantly higher than those in the other two groups(P<0.05).Conclusion The clinical diagnosis of anemia in the blood test can achieve good results, but the rate of misdiagnosis is also high, supplemented by other diagnostic methods can get more accurate results.

貧血是指人体血液中红细胞数量低于正常值的生理状态,多由系统疾病引起,为临床最为常见的一种血液疾病[1-2]。根据贫血发病机制不同,可将贫血明确分为地中海贫血、缺铁性贫血、再生障碍功能性贫血及出血性贫血等类型,因不同类型贫血其相应治疗方法也各有差异[3-4],故学临床正确诊断和鉴别贫血对其后续针对性治疗具有重要作用。基于此研究背景,本文主要探讨了临床贫血诊断中血液检验的应用价值,结果如下。

1 资料与方法

1.1 一般资料 选取2014年8月至2015年8月我院收治的100例贫血患者为研究对象,所有患者均经临床诊断确诊。符合地中海贫血诊断标准47例,符合缺铁性贫血诊断标准53例。根据患者贫血类型予以分组,其中,地中海贫血组男22例,女25例;年龄15~59岁,平均年龄(35.5±3.6)岁。缺铁性贫血组:男25例,女28例;年龄17~61岁,平均年龄(36.1±3.5)岁。同时选取同期于我院行体检的40例健康体检者为对照组,其中男21例,女19例;……
