Maxime Dely: The Human Eye – Irreplaceable Guardian of Blood Transfusion

Maxime Dely, Sales and Application Specialist in Therapeutic Apheresis and Cell Therapy, shared a post on LinkedIn:

“The human eye: Irreplaceable guardian of blood transfusion

In an era where artificial intelligence is revolutionizing medicine and robotization is transforming our laboratories, one field remains steadfast: visual control in blood transfusion.

Colorimetry: diagnosis at a glance

Every blood product tells a story through its color.

Turbid plasma? It’s lipemic.. A greenish tint? Trace of oral contraceptives. A pinkish coloration? Sign of hemolysis.

These instant observations guide our daily decisions.

Red blood cell concentrates reveal their quality through the coloration of the supernatant after storage. Simple, yet no machine can replace this human vigilance.

Swirling: when platelets dance

The most fascinating control? Platelet “swirling” – that whirling dance observed with the naked eye that testifies to their viability. An absent movement immediately alerts to degradation.

The leuko-platelet layer, with its creamy hue, also provides information on residual platelet quantity.

Expertise that cannot be digitized

These visual controls are essential safety barriers. Each professional develops a particular acuity, an abilty to perceivesubtle nuances.

This expertise is transmitted, refined – but cannot be robotized.

Blood transfusion illustrates the perfect balance between technology and human expertise. Automated systems optimize, IT systems trace, but it’s the trained eye that validates final quality.

Let’s value this human dimension

Behind every transfused bag lies the attentive gaze of a professional. In blood transfusion, the human eye remains our most precious safety instrument.”
