The total 25-hydoxy-vitamin-D (t25OHD) level can be assessed by various methods and reflects vitamin D intake. Results are influenced by the serum variables affected by dialyses.Aims: To examine t25OHD and bioavailable vitamin D (b25OHD) by two methods in patients on peritoneal-(PD) and hemodialysis (HD).Methods: We studied 37 HD (64±15 years) and 36 PD (63±18 years) patients. The t25OHD was assessed by chemiluminescence ...

The total 25-hydoxy-vitamin-D (t-25OHD) level reflects the supply of vitamin D, but is also influenced by the levels of 25OHD binding proteins (DBP). 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,...
