Iron deficiency and thrombocytosis.

Area of Science:

• Hematology
• Clinical Biochemistry

Background:

• Textbooks commonly associate iron deficiency (ID) with reactive thrombocytosis.
• The clinical significance of this association in healthy populations requires further investigation.

Purpose of the Study:

• To investigate the correlation between serum ferritin levels and platelet counts in a large cohort of healthy blood donors.
• To determine if low ferritin levels are associated with elevated platelet counts in a healthy population.

Main Methods:

• Retrospective analysis of 130,345 blood counts and ferritin measurements from 22,046 healthy blood donors (1996-2014).
• Statistical analysis to assess the correlation between serum ferritin and platelet count, adjusting for relevant covariates.

Main Results:

• No significant correlation was observed between serum ferritin levels and platelet count in male or female donors.
• Adjusting for age, donation history, and ferritin deciles did not alter the negligible association.
• The findings suggest that low ferritin and platelet count are not clinically linked in healthy individuals.

Conclusions:

• The study did not find a correlation between low serum ferritin and platelet count in healthy blood donors.
• The textbook association of iron deficiency with reactive thrombocytosis may not apply to healthy donor populations.
• Further research is recommended in patient groups with severe anemia or inflammation.
