What this test is

The comprehensive vitamin panel measures levels of 13 different vitamins in the blood. It is designed to detect deficiencies across a wide range of water-soluble and fat-soluble vitamins. The panel includes vitamins A, B1, B2, B3, B4, B5, B6, and others as specified by the ordering clinician.

What it measures

  • Vitamin A — reflects fat-soluble vitamin status important for vision and immune function
  • Vitamin B1 (thiamine) — reflects energy metabolism and nerve function
  • Vitamin B2 (riboflavin) — reflects energy production and cellular function
  • Vitamin B3 (niacin) — reflects metabolism and skin health
  • Vitamin B5 (pantothenic acid) — reflects energy metabolism and hormone synthesis
  • Vitamin B6 (pyridoxine) — reflects amino acid metabolism and nervous system function
  • Vitamin B12 — reflects red blood cell formation and nerve health
  • Folate (vitamin B9) — reflects cell division and red blood cell production
