Abstract

Context: Anaemia is a common clinical disorder in rural India best diagnosed by automatic analyser, which detects haemoglobin concentration in the blood sample. However, in rural areas, this technology is not accessible. Instead, Sahli's method, being inexpensive and low in expertise, is employed here.

Aims: To compare the values of haemoglobin concentration estimated by Sahli's method and the automatic analyser.

Settings and design: A sample of 130 volunteers from both genders in all age groups was randomly selected from a rural health camp, organized in the city of Barabanki, U.P., India. A cross-sectional analytical study was planned.

Methods and materials: Venous blood samples were obtained after taking due consent, and haemoglobin estimation was done using both Sahli's method and the automatic analyser, respectively.

Statistical analysis used: Data analysis was done using IBM SPSS (Statistical Package for the Social Sciences) Software Version 21.0, Armonk NY, and expressed in terms of mean ± standard deviation (SD), and the result was compared using the Chi-square test, Pearson's regression coefficient and Student's T-test. P value <0.05 was considered statistically significant.

Results: Regression analysis showed a weak inverse correlation of haemoglobin concentration obtained via automatic analyser and individual's age, in both genders (r values = -0.132 and -0.148, respectively). However, Sahli's method could not demonstrate any such significant pattern (r values = 0.002 and -0.087, respectively). The values of haemoglobin estimation by Sahli's method (10.57 ± 2.59 g/dl) varied significantly from the automatic analyser (10.90 ± 2.54 g/dl) (P value = 0.0015).

Conclusions: Sahli's method is not efficacious as a diagnostic tool even in a rural, low-budget setup. A weak inverse correlation is seen between blood haemoglobin concentration and age in both sexes.

Sahli方法在印度农村卫生机构中作为血红蛋白估计工具的有效性。
背景:贫血是印度农村常见的临床疾病,最好通过自动分析仪诊断,它检测血液样本中的血红蛋白浓度。然而,在农村地区,这种技术是无法获得的。相反,Sahli的方法,既便宜又不专业,在这里被采用。目的:比较Sahli法与全自动血球分析仪测定的血红蛋白浓度。环境和设计:从印度联合普邦巴拉班基市组织的一个农村健康营中随机抽取了130名各年龄段的男女志愿者。计划进行横断面分析研究。方法和材料:静脉血经同意后采集,分别采用Sahli法和自动分析仪测定血红蛋白。采用统计学分析:采用IBM SPSS (Statistical Package for the Social Sciences) Software Version 21.0, Armonk NY进行数据分析,以均数±标准差(SD)表示,比较采用卡方检验、Pearson回归系数和Student’st检验。结果:回归分析显示,通过自动分析仪获得的血红蛋白浓度与个体年龄呈弱负相关(r值分别为-0.132和-0.148)。然而,Sahli的方法不能证明任何这样的显著模式(r值分别= 0.002和-0.087)。Sahli法测定的血红蛋白值(10.57±2.59 g/dl)与自动分析仪测定的值(10.90±2.54 g/dl)差异显著(P值= 0.0015)。结论:Sahli的方法作为诊断工具,即使在农村,低预算设置是无效的。血红蛋白浓度与男女年龄呈微弱的负相关。
