Sufficient to deficient levels. Standardizing vitamin D assays is therefore essential. There are precedents for programs like the VDSP.

Sponsored by the CDC multiple standardization-certification programs provide accuracy-based standards for tests across manufacturers and methods. The CDC Hormone Standardization HoSt Program for example. The objective of the Centers for Disease Control and Preventions Vitamin D Standardization-Certification Program is to improve the diagnosis treatment and prevention of diseases and disorders by assuring accurate and reliable clinical vitamin D measurements.
