Measuring haemoglobin levels

A new AI-powered imaging-based tool has been developed to estimate haemoglobin levels. 

It was created using a microfluidic chip and an AI-powered automated microscope designed for deriving the total as well as differential counts of blood cells.

The haemoglobin testing solution is possible thanks to the design behind the microfluidic chip, a customised biochemical reagent, optimised imaging, and an image analysis procedure specifically tailored to enable the good clinical performance of the medical diagnostic test.

The data from the microfluidic chip in combination with an automated microscope was comparable with the predictions of haematology analysers. A validation study showed the method meets regulatory standards.

The automated microscope, which normally uses a combination of red, green, and blue LEDs, used only the green LED during the haemoglobin estimation mode, because the optimised reagent (SDS-HB) complex absorbs light in the green wavelength.
