Overview for HemoCue 121721 Hb 201+ Hemoglobin Analyser

The HemoCue® Hb 201+ System has become a standard-bearer in the blood testing space, offering lab accuracy and ease of use to healthcare providers around the world. Professionals use it to make the correct decision at each point of care. This hand-held analyzer offers many features and benefits, and gives the user maximum flexibility and mobility so that they can use the system just about anywhere. 

Precision and accuracy: The HemoCue® Hb 201+ System is calibrated against the ICSH method, and the accuracy of the system is ±1.5%. The system also uses two wavelengths the measure the contents of the cuvettes, to compensate for unusually high levels of white blood cells or lipids. Because of this, there is hardly a need to recalibrate the instrument when moving from lab to lab or when using new cuvettes. The results from these tests consequently match those of a central laboratory.

User friendly: This CLIA-waived system requires only very minimal training and is so easy to learn that even non-laboratory personnel could quickly learn to use it safely and accurately. The HemoCue® Hb 201+ System is factory calibrated, and its settings are verified every time the unit is turned on. Its ease of use extends to maintenance, as its built-in self-test feature gets rid of the need for a control cuvette. The design of the cuvette holder also reduces the need for cleaning.

How it works: Results are produced when a modified azidemethemoglobin reaction happens in the cuvettes. This reaction happens when erythrocytes react with sodium deoxycholate to release hemoglobin. The hemoglobin is converted from the ferrous to the ferric state to form methemoglobin with the use of sodium nitrite, and the new methemoglobin compound combines with azide to form azidemethemoglobin. Double wavelengths of 570nm and 880 nm are used to measure hemoglobin content and compensate for turbidity.
