Hb estimation at point of care using cyanmethaemoglobin method

Background: Accurate estimation of haemoglobin (Hb) is an essential prerequisite for detection anaemia and assessing response to treatment. In India the gold standard cyanmethaemoglobin method used Hb in tertiary care institutions but accurate methods are not being primary secondary healthcare settings. Major national surveys have demonstrated feasibility accuracy by indirect (ICM). However, ICM has been point because reports that underestimates Hb. A study was taken up compare direct (DCM) (ICM) method.Methods: ANMs laboratory technicians pipetted out duplicate samples blood both estimation. Another trained technician undertook using colorimeter all samples. values between duplicates were compared.Results: There excellent concordance means frequency distribution when estimated DCM or also done one other. Bland Altman Plots confirmed across levels there estimation.Conclusions: Indirect accurate. It can be at screening improvement after treatment especially health
