Comprehensive blood test measuring 11 nutrients to identify deficiencies in individuals following high-protein diets.
This test panel measures vitamin B1 (thiamine), vitamin B7 (biotin), vitamin D, vitamin E, calcium, chromium, vitamin B9 (folate), iodine, iron, ferritin, magnesium, and molybdenum levels in your blood. Identifying and addressing nutritional deficiencies is crucial for overall health, as your body doesn't produce most nutrients. Dietary restrictions, like high-protein diets, can hinder nutrient intake. This test helps you and your doctor determine if dietary modifications or supplementation are necessary to maintain optimal health.

Who Is This For?
Anyone living in regions with limited sunlight or who spends most time indoors. People experiencing bone pain, muscle weakness, or frequent illness. Those with darker skin (melanin reduces vitamin D synthesis). Older adults, as the skin's ability to produce vitamin D decreases with age. Anyone supplementing with vitamin D who wants to verify they're in the optimal range.
What's Included
Preparation Required
No fasting required. No special preparation needed. If you supplement with vitamin D, continue your normal dosage — the test is measuring your steady-state level, not an acute response.
Biomarkers Tested
13Essential for energy metabolism and nervous system function. Thiamine deficiency can cause beriberi (nerve damage) and Wernicke-Korsakoff syndrome. Common in chronic alcohol use and malabsorption conditions.
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.
The best indicator of overall vitamin D status. Vitamin D is essential for calcium absorption, bone health, immune function, and mood regulation. Deficiency is extremely common, especially in northern latitudes, and linked to increased disease risk.
Imbalances in gut pH influence short-chain fatty acid production and their effects.
The most abundant mineral in the body, essential for bone health, muscle contraction, nerve function, and blood clotting. Blood calcium is tightly regulated by parathyroid hormone and vitamin D. Abnormal levels can indicate parathyroid disorders.
An essential trace mineral in its trivalent form (Cr³⁺), important for insulin signalling and glucose metabolism. Hexavalent chromium (Cr⁶⁺) from industrial exposure is carcinogenic. Testing measures total chromium levels.
Vitamin B9 (Folate) is crucial for DNA synthesis and repair. Low levels can lead to anemia and other health issues.
Iodine is an essential trace element and an integral component of thyroid hormones. Thyroid hormones are required for normal growth and development of tissues and maturation of our bodies. Approximately 80% of iodine is excreted in the urine, making it a good marker of the previous day's intake.
A mineral essential for oxygen transport (in hemoglobin), energy production, and immune function. Serum iron measures the amount circulating in blood, but ferritin and TIBC provide a more complete picture of iron status.
The primary iron storage protein. Ferritin reflects total body iron stores and is the first marker to drop in iron deficiency. However, ferritin also rises with inflammation, infection, and liver disease, which can mask true iron deficiency.
Involved in over 300 enzymatic reactions including energy production, muscle function, and nerve signaling. Magnesium deficiency is common and associated with muscle cramps, anxiety, insomnia, and increased cardiovascular risk.
Trace mineral involved in enzyme function and metabolism.
Essential for thyroid hormone production and overall metabolic regulation.
