Medical devices; reclassification and codification of vitamin D test system--FDA. Final rule

The Food and Drug Administration (FDA) is announcing that it has issued an order in the form of a letter to INCSTAR Corp. reclassifying INCSTAR 25-Hydroxyvitamin D 125I Radioimmunoassay (RIA). This radioimmunoassay device is intended for use in clinical laboratories for the quantitative determination of 25-hydroxyvitamin D (25-OH-D) and other hydroxylated metabolites of vitamin D in serum or plasma to be used in the assessment of vitamin D sufficiency. The device and substantially equivalent devices of this generic type were reclassified from class III (premarket approval) to class II (special controls). Accordingly, the order is being codified in the Code of Federal Regulations.
