Blood cell size may reveal COVID-19 severity in ICU patients
NCT ID NCT07244731
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed study from Ankara University looked at 146 severe COVID-19 patients in the ICU. Researchers measured red blood cell distribution width (RDW), a marker of variation in red blood cell size, to see if it could predict whether patients would need a breathing tube or die. The goal was to find a simple, inexpensive tool to help doctors make better decisions in the ICU.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this could help doctors use a simple blood test to predict which COVID-19 patients in the ICU are at higher risk of death or needing a breathing tube.
What could go wrong
This is an observational study, not a treatment trial. It only shows a possible link, not cause and effect. The results may not apply to all COVID-19 patients.
