Tests Vitamin D, B12, and Folate — the three vitamins most frequently deficient in adults. A quick, affordable screen for fatigue, brain fog, and immune health. Vitamin D, B12, and Folate are the three most commonly deficient vitamins in the US population. Vitamin D deficiency affects an estimated 42% of American adults and is linked to fatigue, bone loss, depression, and weakened immunity. B12 deficiency causes neurological symptoms, anemia, and cognitive decline — especially in older adults and those on plant-based diets. Folate (B9) is essential for DNA synthesis, red blood cell formation, and is critical during pregnancy. This panel provides a quick, affordable screen for the three most impactful vitamin deficiencies. For a more comprehensive assessment including minerals, consider our Vitamin & Mineral Panel. **Clinical use:** Focused vitamin-status check: Vitamin D, Vitamin B12, and Folate — the three most commonly deficient vitamins.

[Vitamin D](https://www.test-well.com/tests/vitamin-d), [Vitamin B12](https://www.test-well.com/tests/vitamin-b12), and [Folate](https://www.test-well.com/tests/folate). 3 individual tests catching the most prevalent reversible vitamin deficiencies in one draw — the three vitamins clinically deficient in the largest share of US adults. ### How is this different from the Vitamin & Mineral Panel? Basic Vitamin Deficiency Panel focuses on the three core vitamins ($89.99, 3 tests: D, B12, Folate). [Vitamin & Mineral Panel](https://www.test-well.com/tests/vitamin-mineral-panel) at $189 adds minerals (Magnesium, Zinc, Calcium, Selenium, Copper) and more. Use Basic Vitamin Deficiency for a quick fatigue workup; Vitamin & Mineral for full nutritional status. ### Which vitamin deficiency is most common? [Vitamin D](https://www.test-well.com/tests/vitamin-d) (~42% of US adults), then [B12](https://www.test-well.com/tests/vitamin-b12) (especially after 50 or on PPIs/metformin), then [Folate](https://www.test-well.com/tests/folate) (rare in the US due to fortification but more common on certain medications). ### How much does the Basic Vitamin Deficiency Panel cost without insurance? On TestWell, the Basic Vitamin Deficiency Panel is $89.99. Ordering the same tests separately would be about $155. Quest Direct lists comparable bundles at $169, walk-in hospital labs typically bill $400-600 without insurance. ### Do I need to fast? No fasting required for Vitamin D, B12, or Folate. It does help to hold high-dose vitamin supplements for 24 hours before the draw so results reflect your true baseline rather than what you just took. ### When should I retest after starting supplements? Vitamin D: 8-12 weeks after starting or changing a dose. B12: 6-8 weeks. Folate: 8 weeks. Always retest before increasing doses — Vitamin D is fat-soluble and can accumulate to toxic levels. ## How to order 1.
