Comprehensive blood test measuring vitamin B2 (riboflavin), B3 (niacin), and B5 (pantothenic acid) levels to identify deficiencies.
This test panel measures the levels of vitamin B2, vitamin B3, and vitamin B5 in your blood. Identifying and addressing nutritional deficiencies are important steps toward better health. Your body does not produce most nutrients, so you must get them through food or supplements. How nutrients work in your body is influenced by more than just what you eat. These factors include genetics, age, health conditions, medications, metabolism, and how well your body absorbs nutrients.

Who Is This For?
Vegetarians and vegans (at higher risk of B12, iron, and zinc deficiency). Older adults, as nutrient absorption decreases with age. Anyone on restrictive diets or with digestive conditions affecting absorption. People experiencing unexplained fatigue, brain fog, poor wound healing, or hair loss. Athletes with high nutrient demands from training.
What's Included
Preparation Required
Fasting for 8–10 hours is recommended for some nutrient tests but not all — check with your provider. Continue taking your regular supplements unless told otherwise (the test measures your steady-state levels). Morning draws are preferred for consistent results.
Biomarkers Tested
5Vitamin B2 (Riboflavin) is important for energy production and cellular function. Deficiency can cause skin disorders, anemia, and fatigue.
A metal found in canned foods, solder, and industrial materials. While small amounts of inorganic tin are relatively non-toxic, high levels can cause gastrointestinal irritation. Organotin compounds are more toxic and affect the immune and nervous systems.
Measures the level of vitamin B5 (pantothenic acid) in the blood, important for energy metabolism and fatty acid synthesis.
Essential for nerve function, DNA synthesis, and red blood cell formation. B12 deficiency can cause anemia, neuropathy, fatigue, and cognitive impairment. Common in vegans, vegetarians, older adults, and those taking metformin or acid-reducing medications.
Essential for DNA synthesis, cell division, and red blood cell formation. Folate deficiency causes megaloblastic anemia and, during pregnancy, increases the risk of neural tube defects. Works closely with vitamin B12.
