Objective:
To validate hemoglobin (Hb) concentration in venous blood (VB) using the HemoCue 201+ in a subsample of children and women from the Mexican National Health and Nutrition Survey 2022.
Materials And Methods:
Prior to field work 50 HemoCue 201+ devices were verified using venous blood. During the field work 57 children (aged 1-11) and 62 women (aged 12-49) donated 3 mL of VB each. Hb was measured in each device of HemoCue 201+ and in a hematologic autoanalyzer for the validation.
Results:
No significant bias was found in most of the devices. An adjustment criterion was used for 22 devices. Hb mean difference results were -0.049±0.578 g/dL in children and -0.098±0.628 g/dL in women.
Conclusions:
The HemoCue 201+ is a valid tool for estimating Hb concentration to produce reliable estimates of anemia prevalence when using venous blood.
