Comprehensive blood test to measure 7 nutrients potentially affected by soy, peanut, or tree nut allergies.
This test measures the levels of seven essential nutrients in your blood that research has shown can be affected by soy, peanut, or tree nut allergies. These nutrients are crucial for various bodily functions, including energy production, cell growth, and immune system support. Identifying deficiencies allows you and your doctor to determine if supplementation is necessary to improve your overall health and address potential symptoms related to nutrient deficiencies. The test helps ensure you're getting the nutrients your body needs, especially if you have dietary restrictions due to allergies. Early detection and management of deficiencies are key to maintaining optimal health.

Preparation Required
No fasting required. Continue eating your normal diet for at least 2–4 weeks before testing — avoiding suspected trigger foods can cause false negatives. Inform the clinic of any antihistamines or immunosuppressants you're taking, as these can affect results.
Biomarkers Tested
7Essential 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.
Vitamin B6 (Pyridoxine) is important for protein metabolism, cognitive development, and immune function. Deficiency can lead to anemia and neurological issues.
Vitamin B9 (Folate) is crucial for DNA synthesis and repair. Low levels can lead to anemia and other health issues.
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.
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.
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.
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.
