Comprehensive Vitamin Panel in California

What this test measures

This panel quantifies a broad range of vitamins in one order. It includes vitamin A, the B vitamins from thiamine through cobalamin, vitamin C, vitamin D, and vitamins E and K. Each vitamin supports specific functions, from energy metabolism and nerve health to immune function, bone health, and blood clotting. Measuring them together provides a wide view of nutritional status rather than focusing on a single nutrient.

A blood sample is collected by venipuncture at a partner laboratory. Different vitamins require different analytical methods, so the laboratory may use immunoassays, chromatography, or mass spectrometry depending on the marker. Fasting may be requested for certain components, and some vitamins are sensitive to recent intake. Because levels can be influenced by diet, supplements, and health conditions, results are interpreted as a pattern.

People order this panel when they suspect nutritional deficiencies, follow restricted diets, have digestive conditions that affect absorption, or want baseline information. It is a screening tool rather than a diagnosis. A qualified healthcare provider should review the results with your diet, supplement use, and medical history before any changes are considered.
