Celltac α+ MEK-1303

Celltac α+ MEK-1303 from Nihon Kohden is an automatic analyser that integrates haematology (with 3-part leukocyte differentiation), CRP determination and HbA1c testing in a single compact instrument. The system maximises testing efficiency through a single aspiration process, providing combined haematology results including CRP from a single sample.

Haematology with CRP

In certain situations, a CRP test can be more useful than an ESR test, because the markers used in each test behave differently depending on the stage and cause of inflammation. MEK-1303 provides complete haematology results, including CRP, through a single aspiration process.

• CRP as a rapid marker of inflammation.
• Closed Mode for safe operation.

Individual HbA1c test

Monitoring HbA1c is essential for diabetic patients. MEK-1303 provides individual HbA1c results (in HbA1c measurement mode only the HbA1c result is displayed) and is NGSP certified.

DynaHelix Flow technology

This unique technology reduces the “re-entry” of blood cells after passing through the detection aperture: the swirling flow pushes the cells towards the drainage path. The effect is particularly useful for samples with a low cell volume, ensuring accurate CBC results.

Other features (MEK-1300 series)
