25-hydroxyvitamin D is the correct marker for vitamin D status, not 1,25-OH, the active hormone that fluctuates daily without reflecting stores. But 25-OH D results vary significantly between labs because immunoassay and LC-MS/MS mass spectrometry platforms produce different numbers for the same specimen. Reference ranges differ too: some labs flag deficiency below 20 ng/mL; others use 30 ng/mL. If you are tracking D levels longitudinally to monitor supplementation response, staying with the same lab and platform is essential. A 10 ng/mL change on immunoassay may reflect methodological variance rather than a true clinical change. Bring the complete order to ensure we route to your designated lab platform.
Vitamin B12 deficiency is common in strict vegans, older adults whose gastric acid declines with age, and patients taking metformin long-term. Symptoms including peripheral neuropathy, macrocytic anemia, and cognitive changes can appear before serum B12 falls below the lab reference limit. Serum B12 is relatively insensitive; methylmalonic acid and homocysteine are more sensitive functional markers of deficiency. Folate deficiency is common in pregnancy and alcoholism. High supplemental folate can mask B12 deficiency by correcting macrocytic anemia while nerve damage progresses, which is an important reason to test both markers together when evaluating for deficiency.
High-dose biotin supplementation, common in hair, skin, and nail products at 5,000 to 10,000 mcg doses, directly interferes with competitive immunoassay platforms used to measure thyroid hormones, vitamin D, folate, B12, ferritin, and steroid hormones. The interference produces falsely low TSH and falsely elevated free T4, free T3, and other markers. An FDA safety communication warns about this explicitly. If you take biotin supplements, your clinician may recommend withholding them for at least 3 to 7 days before testing. Follow your clinician's specific guidance on the hold period. Disclose all supplements, including those not considered medications, when scheduling your draw.
Comprehensive nutrient panels go well beyond basic vitamin D and B12 to include intracellular B-vitamin assessments, zinc, copper, selenium, magnesium, omega-3 index, and coenzyme Q10. RBC magnesium is more informative than serum for assessing intracellular magnesium status. Specialty functional nutrition labs offer dried blood spot and serum-based micronutrient panels requiring specific collection techniques and temperature-sensitive processing. For these orders, bring the complete collection kit and manufacturer instructions. Multiple tubes with different additives and processing requirements are common. At scheduling, share all kit inserts so we confirm tube types, inversion protocols, and any cold-chain packaging requirements before the visit.

For teams
Clinics, labs, research teams, and employers use Speedy Sticks to extend collection capacity without sacrificing protocol fidelity. API integration, bulk scheduling, and compliance documentation included.

A vitamin deficiency blood test measures levels of key vitamins and micronutrients in the blood—most commonly vitamin D, vitamin B12, and folate—to identify deficiencies that may cause fatigue, bone loss, neuropathy, or other symptoms. Broader panels may include vitamin A, vitamin E, zinc, magnesium, and other nutrients. Speedy Sticks provides mobile phlebotomy for vitamin and micronutrient testing so patients can complete clinician-ordered panels at home.
