Abstract
Aims: Mean platelet volume (MPV) is a measurement based on platelet morphology. We aimed to investigate whether MPV and platelet count exhibit a daily change in relation to the days and gender. Methods: Healthy blood donors aged 18–55 years with no history of the disease and/or drug use participated in the study. MPV values and platelet counts were analyzed with respect to the date of the blood test and the gender of the participant based on a 29–day calendar. Results: A total of 14718 participants (7772 female) were included. The median age of the females and males was similar (38 [range 18–54], and 36 [18–55], p=0.254, respectively). Median platelet count was 278 × 109/L (range 152–448) in females and 244 × 109/L (range 151–439) in males, with a significant difference (p<0.01). The median MPV was 8.9 (range 5.7–12.2) fL in females and 8.4 (range 5.9–12.8) fl in males (p<0.01). MPV and platelet counts were higher in females on all days of the month compared to males. Decreases in MPV values were observed in both females and males on days 9th, 12th, 20th, and 26th, whereas increases in both occurred on days 5th, 15th, 23rd, and 29th. Conclusion: We demonstrated that MPV and platelet count exhibited a daily fluctuating in healthy individuals; MPV values and platelet count were overall higher in females. This study may give a different perspective on future studies of MPV and a lead for evaluating daily changes on other blood parameters.
