Abstract
Vitamin D is a steroid in character and a fat-soluble vitamin. It is produced primarily from cholesterol in the skin and is also taken up in a small amount in the diet. 25(OH)D3 levels are used as an indirect measure of vitamin D levels. Our aim was to investigate the variation in serum 25(OH)D3 levels of patients admitted to the hospital in and around Mardin based on gender, season, and age. 25(OH)D3 concentrations were evaluated at Mardin Training and Research Hospital between 01.01.2017 and 01.01.2020. Our study established subgroups according to gender, season, age, and 25(OH)D3 status. 25(OH)D3 concentration was measured using the chemiluminescence method. A significant decrease was observed in the 25(OH)D3 levels of female (13.62±11.53 ng/ml) patients compared to male patients (12.14±9.38 ng/ml).. A significant increase was detected in the summer and autumn seasons compared to winter and spring (p
