METHOD
Colorimetric endpoint test

PRINCIPLE

In the cyanomethemoglobin method, erythrocytes are lysed by a stromatolytic reagent in the presence of a surfactant and release their hemoglobin into solution. Hemoglobin is oxidized to methemoglobin by ferricyanide, and the methemoglobin is converted into the stable cyanomethemoglobin by addition of KCN. The absorbance of cyanomethemoglobin is measured at 540 nm and colour intensity is proportional to hemoglobin concentration.

SAMPLE:
Collect whole blood with EDTA using aseptic technique. Whole blood collected with EDTA is stable for one week
at 2 - 8°C.

REFERENCE VALUES
Adult Males 13.0 - 18.0 g/dl
Adult Females 11.0 - 16.0 g/dl
Children 10.0 - 14.0 g/dl
Newborns 14.0 - 23.0 g/dl

REAGENTS

Reagent I : Cyanomethemoglobin reagent
Methemoglobin Std : 60 mg/dl (15 g/dl) store at 2-8°C

Interfering substances

Falsely elevated values are found in Lipaemic samples, Abnormal plasma proteins etc. Numerous drugs exert an in vivo effect to decrease blood hemoglobin.

MANUAL PROCEDURE

PIPETTE INTO TEST TUBE
  BLANK STD SAMPLE
Sample - - 20 µl
Standard - 20 µl -
Reagent 5000 µl 5000 µl 5000 µl

Mix well, Incubate at r.t. for 5 mins. Measure final
absorbance of the sample (Ac) and standard (As)
against the reagent blank. At 540 nm (520-550 nm)

CALCULATION AND LINEARITY
Ac/As x Conc. Std. = g/dl HEMOGLOBIN

The hemoglobin assay shows a linearity upto 20 g/dl.
If the hemoglobin values are greater than 20 g/dl, dilute 1:1
with deionised water. Multiply result by 2.
