How the Chempaq Analyzers works
• The Chempaq XBC and XDM 701 uses advanced technology to measure the different parameters.A single drop of blood is enough to perform the analysis. A medium–sized to large drop of blood is enough to supply the necessary approx. 20 microlitres (μL).

• The PAQ contains a chemical solution, called a reagent solution, which
dilutes the blood, causing a chemical reformulation. The reagent depends on the type of test.

• The Analyzers use a sensor to count blood cells, which can differentiate between each cell type and sub–groups, by measuring their size, expressed as a change in the electrical impedance, when the cells pass the sensor (impedance technology).

• Various reagents are used to measure hemoglobin using the WBC or CBC PAQ and HGB cuvette. In both instances, the reagent blyses the red blood cell membrane, releasing the hemoglobin. The reagent further causes chemical reformulation of the hemoglobin released. These form a stable methemoglobin complex.

• The WBC and CBC PAQ and HGB cuvettes measure the amount of hemoglobin using spectrophotometry. This measures the amount of light the methemoglobin complex solution absorbs. The Analyzers use light with two different wavelengths (colours) to perform the hemoglobin measurement.

• The Chempaq Analyzers do not state which disease or illness (if any) the patient may be suffering. It is the responsibility of the doctor to use his or her medical knowledge to interpret these results.
