Trombocyt-leukocyt-ratio
BloedcelsysteemDeze marker vergelijkt het bloedplaatjesaantal met het totale aantal witte bloedcellen en weerspiegelt zo de stollingsactiviteit ten opzichte van de immuunactiviteit.

Waarom dit belangrijk is
The platelet-to-WBC ratio helps assess systemic inflammation, infection severity, and bone marrow function. A low ratio may indicate severe infection (WBCs elevated, platelets consumed), inflammatory conditions, or hematologic malignancies where WBC production is abnormally high. An elevated ratio can suggest reactive thrombocytosis, recovery from infection, or certain myeloproliferative disorders. The ratio is particularly useful for predicting outcomes in sepsis, assessing cardiovascular risk (as both components influence thrombosis and inflammation), and monitoring treatment response in infections or inflammatory conditions.
Changes in the ratio over time often provide earlier warning of clinical deterioration or improvement than individual cell counts alone.
Hoe dit samenhangt met andere biomarkers
- The Platelet-to-WBC Ratio is a composite hematologic marker reflecting the balance between platelet production and immune-cell activation.
- A low ratio (relatively elevated Leukocytes with normal or low Thrombocytes (Platelets)) is observed in systemic infection, sepsis, and severe inflammation.
- A high ratio with normal WBC and elevated platelets is seen in reactive thrombocytosis (post-surgery, inflammation, malignancy) or essential thrombocythemia (a bone marrow disorder that overproduces platelets).
