Blood test ratio may spot deadly lung clots faster

NCT ID NCT07023705

First seen Jun 27, 2026 ยท Last updated Jun 27, 2026

Summary

This study looked at whether a ratio of two blood cell types (monocytes and large platelets) can help diagnose acute pulmonary embolism, a serious blood clot in the lungs. Researchers analyzed blood samples from 53 patients who had a CT scan to confirm or rule out the clot. The goal was to see if this simple, inexpensive test could be a useful diagnostic tool.
