Tests both B12 and folate together — two vitamins that work together for blood and nerve health. B12 and folate work together in the production of red blood cells and DNA synthesis. A deficiency in either can cause a type of anemia called megaloblastic anemia, as well as neurological symptoms. Testing both together helps distinguish between the two deficiencies, which is important because treating one while the other is truly deficient can mask symptoms and cause complications. **Clinical use:** Vitamin and nutrient testing identifies deficiencies that can drive fatigue, immune dysfunction, neurological symptoms, and long-term disease risk — and confirms that supplementation is working. ## Who should order it? Anyone with restrictive diets (vegan, low-fat, low-carb), malabsorption conditions, fatigue, hair loss, mood changes, or currently supplementing and wanting to verify dosing. ## Biomarkers measured - [Vitamin B12](https://www.test-well.com/biomarkers/vitamin-b12) - [Folate](https://www.test-well.com/biomarkers/folate) ## Price by lab | Lab | Test price | All-in (with $6 fee) | Notes | | --- | --- | --- | --- | | Quest Diagnostics | $36.99 | $42.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | | Labcorp | $46.99 | $52.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | | BioReference (NY & NJ) | $37.99 | $43.99 | New York and New Jersey orders route here automatically | Rhode Island is not served.
