Summary
This study establishes crucial platelet count reference ranges for young adult Iranians, essential for accurate medical diagnosis and research. Findings reveal differences compared to Caucasian and African populations.
Area of Science:
- Hematology
- Clinical Pathology
Background:
- Limited data exists on platelet indices reference ranges in Iran and surrounding regions, with prior studies having small sample sizes.
- Establishing population-specific reference values is vital for accurate medical research and clinical practice.
Purpose of the Study:
- To determine the reference values for platelet indices in a large cohort of young adult Iranians.
- To provide essential data for medical research and clinical practice in the region.
Main Methods:
- A cross-sectional survey was conducted on 19,993 young adult Iranians undergoing pre-marriage screening.
- Platelet indices including platelet count, platelet distribution width, plateletcrit, and mean platelet volume were measured using an automated hematology analyzer (Technicon H2).
Main Results:
- The study established 95% reference intervals for platelet indices in Iranians: platelet count (145-356 x 10^9/l), platelet distribution width (40.2-57.4%), plateletcrit (0.13-0.32%), and mean platelet volume (7.4-10.7 fl).
- Significant sex-based differences were observed for the first three indices (platelet count, PDW, and plateletcrit).
- Iranian reference values for platelet indices were found to be lower than Caucasians but higher than Africans.
Conclusions:
- The established reference values for platelet indices in young adult Iranians differ from international data.
- These findings underscore the importance of using population-specific reference ranges for accurate interpretation of platelet indices in clinical settings and research.
