Vitamin D, 25-Hydroxy is a blood lab test that measures serum levels of 25-hydroxyvitamin D — the primary circulating form used to assess overall vitamin D status in the body. Ordered through Quest Diagnostics, this test supports informed decisions about supplementation, dietary intake, and bone, immune, and metabolic health monitoring. It is appropriate for adults seeking a baseline measurement or ongoing tracking of their vitamin D levels.
Why It's Worth Considering: The 25-hydroxy form is the clinically accepted marker for vitamin D sufficiency, and Quest Diagnostics processes specimens through standardized, high-volume reference laboratories for consistent, reliable results.
