Vitamins & Nutrients

Vitamin D (25-OH D) is the main blood marker used to show circulating vitamin D status. It reflects the amount of 25-hydroxyvitamin D in the blood, which comes from diet, supplements, and sunlight-related production. On a Vitamin D blood test or Vitamin D on a lab report, this value is often reviewed to compare with the Vitamin D reference range and other nutrient markers.

Vitamin B12 is a lab value that shows the amount of vitamin B12 measured in a blood sample. On a lab report or blood test, it helps describe nutritional status and how the result compares with the Vitamin B12 reference range. High Vitamin B12 and low Vitamin B12 can both reflect changes in intake, absorption, or sample-related factors.

Folate is a lab value that reports the amount of Folate measured in a blood sample. Folate on a blood test is used in vitamins and nutrients panels to show how that nutrient level compares with the Folate reference range. It is often read with red cell markers such as RBC, Hct, and MCV to provide a fuller picture of blood composition.

Zinc (Zn) is a trace mineral measured on some blood tests to show the amount of Zn in circulation. On a lab report, it is usually reviewed as part of a Vitamins & Nutrients panel, where it helps describe overall nutrient balance and possible variation in intake, absorption, or loss.

Selenium (Se) is a trace element measured in blood that helps describe nutrient status and how much selenium is circulating at the time of the test. Selenium on a lab report or selenium on a blood test is usually interpreted with the Selenium reference range, the testing method, and related vitamins and minerals.

Vitamin B6 is a vitamins and nutrients lab value that reflects the amount of Vitamin B6 measured in blood. On a blood test, it is often reviewed as part of the Vitamins & Nutrients panel to compare the result with the Vitamin B6 reference range. High Vitamin B6 or low Vitamin B6 can reflect differences in intake, supplement use, hydration, or lab method.

Vitamin A is a blood measurement of retinol, the main circulating form of vitamin A in the body. On a lab report, it reflects how much vitamin A is present in blood at the time of testing. In a Vitamins & Nutrients panel, Vitamin A helps describe nutritional status and how blood values compare with the Vitamin A reference range.

Vitamin E is a blood test value that measures the amount of Vitamin E (alpha-tocopherol) circulating in serum or plasma. On a lab report, Vitamin E shows nutrient status and is commonly reported in mg/L. The Vitamin E test result is interpreted against the Vitamin E normal range printed by the laboratory. Values can shift with diet, fat absorption, and lipid status, since Vitamin E travels with blood lipids. A Vitamin E blood test is often read with other fat-soluble vitamin values for context.

Vitamin K is a lab value used to show the level of vitamin K in a blood sample. On a lab report, it helps describe whether the measured Vitamin K is within the normal range or outside it. In the Vitamins & Nutrients panel, a Vitamin K test can be used to track nutrition patterns, supplement use, and other factors that influence blood levels.

Vitamin C is a blood or plasma measurement that reflects the amount of this nutrient circulating in the sample. On a lab report, Vitamin C helps show whether the level is within the normal range and how it compares with other nutrient values in the Vitamins & Nutrients panel. High Vitamin C or low Vitamin C can reflect diet, recent intake, hydration, and other factors that change what a Vitamin C test result shows.

Vitamin B1 (Thiamine) (B1) is a laboratory value that reports the amount of thiamine measured in blood, usually as part of a Vitamins & Nutrients panel. On a lab report or blood test, B1 helps show whether the measured level is within the Vitamin B1 (Thiamine) normal range and how the result compares with the lab’s reference range.

Vitamin B2 (Riboflavin) (B2) is a nutrient-related lab value that reflects riboflavin status in blood or a related specimen. It is used to summarize how much B2 is present and how that result compares with the Vitamin B2 (Riboflavin) normal range on a lab report or blood test. In the Vitamins & Nutrients panel, the B2 test helps organize nutrition-related data alongside other measured markers.

Vitamin B3 (Niacin) (B3) is a lab value that refers to the amount of niacin-related material measured in blood or related specimens. On a Vitamin B3 (Niacin) lab report, it helps describe nutritional status and how intake, use, and short-term balance may vary. B3 is often reviewed in a Vitamins & Nutrients panel alongside other markers of nutrient status.

Copper (Cu) is a trace mineral measured in blood to show how much Cu is circulating in the sample. On a lab report, Copper is usually used as part of a Vitamins & Nutrients panel to help show nutritional status and balance with related markers. The Copper test result is read with reference ranges, age, sex, and lab method in mind.

Manganese (Mn) is a trace mineral measured on some lab reports to show how much manganese is present in a blood sample. It is not a routine part of most general blood panels, but it can appear in nutrient-focused testing. Manganese test results are interpreted with the Mn reference range and the lab method used.

Chromium is a trace mineral measured in blood or serum to describe the amount of Chromium present in the sample. On a Chromium lab report, the result helps show whether the level falls within the Chromium normal range and how it compares with common reference values. It is often ordered in Vitamins & Nutrients panels to give a broader picture of nutrient status and exposure.

Methylmalonic Acid (MMA) is a small organic compound that builds up in the blood when active vitamin B12 is in short supply at the cellular level. Because of that, MMA is widely cited as the most sensitive lab marker of functional B12 status — often more reliable than serum B12 itself, especially in older adults and people with kidney function in mind. Many lab reports include MMA alongside or instead of vitamin B12 when more precise B12 status is wanted. BloodSight reads every MMA value from your uploaded reports and charts the trajectory across visits.
