We aimed studying t-25OHD and bioavailable 25OHD (bio-25OHD) levels in healthy females with different reproductive ages.Methods: t-25OHD, bio-intact parathormone (PTHi-1–84) (ECLIA, cobas e411, Roche), DBP (turbidimetry, Dako), calcium and albumin (Alb) levels were measured by routine methods (Modular,...
