Hemoglobin determinations will usually be performed by an automated cell counter from a tube of well-mixed EDTA-anticoagulated blood filled to a predetermined level. In this assay, all forms of hemoglobins are converted to the colored protein cyanomethemoglobin and measured by a colorimeter.

How do you calculate hemoglobin?

Calculated hemoglobin: The ADVIA back-calculates a hemoglobin (calculated hemoglobin) from the CHCM (i.e. calculated hemoglobin = (CHCM x MCV x RBC count) ÷ 1000.

How can I check my hemoglobin levels at home?

The BIOSAFEAnemia Meter is the first FDA-approved, hand-held device that can be conveniently used at home to test hemoglobin levels (Figure 1). Low levels of hemoglobin may indicate anemia. Thus, the Anemia Meter may be used as an additional screening method.
