Haemoglobin determination without cyanide on Hemalog-8

Area of Science:

• Clinical Chemistry
• Hematology

Background:

• The cyanmet-haemoglobin method is standard for haemoglobin determination in hospital laboratories.
• This method, recommended by the International Committee for Standardization in Haematology (ICSH), uses cyanide, posing safety risks.
• Safe handling and preparation of cyanide reagents are crucial.

Purpose of the Study:

• To investigate the replacement of cyanide-containing reagents with a cyanide-free alternative for haemoglobin determination.
• To evaluate the impact of this reagent change on the Hemalog-8 analyzer.

Main Methods:

• A cyanide-free reagent was substituted for the standard cyanide reagent in the Hemalog-8 analyzer.
• Haemoglobin analysis was performed using both the original and the modified reagent systems.

Main Results:

• The substitution of the cyanide reagent with a cyanide-free alternative did not alter the haemoglobin analysis results.
• The Hemalog-8 analyzer maintained its analytical performance after the reagent modification.

Conclusions:

• A cyanide-free reagent can be successfully implemented in the Hemalog-8 analyzer for haemoglobin determination.
• This modification enhances laboratory safety without compromising the accuracy of haemoglobin measurements.
