A Simple Micromethod for 25-Hydroxyvitamin D Estimation [PDF]

Annals of Clinical Biochemistry: International Journal of Laboratory Medicine, 1979
A quick and simple method for estimating 25-hydroxyvitamin D is described. It involves dichloromethane extraction followed by competitive protein-binding assay without chromatography. This assay can be performed on 100 μl of serum and enables 50 samples to be estimated in one working day.

Analytical Performance Specifications for 25-Hydroxyvitamin D Examinations [PDF]

Nutrients, 2021
Currently the 25-hydroxy vitamin D (25(OH)D) concentration is thought to be the best estimate of the vitamin D status of an individual. Unfortunately, its measurement remains complex, despite recent technological advances. We evaluated the biological variation (BV) of 25(OH)D in order to set analytical performance specifications (APS) for measurement ...
