Abstract:
Objective To establishe the reference range of low hemoglobin density (LHD ％) of health population in Humen District of Guangdong,and discuss the clinical application value.Methods Randomly selected from January 2015 to September 2016 in Humen Hospital of Dongguan City physical examination of 1 650 cases of healthy people as control group,and selected the same period by the clinical diagnosis of iron deficiency anemia (iron-deficiency anemia,IDA) group,67 cases of patients with IDA Sysmex XT-1800i fully automatic blood analyzer were used respectively to detect blood routine,and then based on the average haemoglobin concentration (mean corpuscular hemoglobin concentration,MCHC),calculate the LHD％,and the calculation results were analyzed.Results The control healthy crowd LHD％ value was 2.41％ ± 0.85 ％,95％ reference range was 0.74 ％ ～4.08％,male was higher than the female,the difference was statistically significant (t =3.209,P＜0.05).IDA patients before treatment LHD％ was 30.97％ ± 18.65％,significantly higher than the control group,the difference was statistically significant (t=19.536,P＜ 0.01),and with the level of hemoglobin (Hb) showed a negative correlation (r=-0.4313).LHD％ values after treatment in patients with IDA group were significantly lower,but the recovery speed was slower than the Hb and MCHC.By ROC curve analysis,when the cut-off of LHD％ value was 4.10％,the LHD％ for IDA early diagnostic sensitivity of 96.78％,specificity of 100％.Conclusion Established the reference range of low hemoglobin density (LHD ％) of healthy population in Humen district of Guangdong,and LHD％ is IDA good indicator of early diagnosis and curative effect of dynamic monitoring.
