Comprehensive blood test to measure folate levels potentially affected by calcium channel blockers.
This test measures the level of vitamin B9 (folate) in your blood, a nutrient crucial for red and white blood cell production, tissue growth, DNA building, and energy conversion. Calcium channel blockers can hinder nutrient absorption, making this test vital for identifying potential deficiencies. Addressing folate deficiency is crucial for overall health and preventing irreversible damage, particularly to the nervous system. The test helps you and your doctor determine if folate supplementation is necessary.

Who Is This For?
Vegetarians and vegans (at higher risk of B12, iron, and zinc deficiency). Older adults, as nutrient absorption decreases with age. Anyone on restrictive diets or with digestive conditions affecting absorption. People experiencing unexplained fatigue, brain fog, poor wound healing, or hair loss. Athletes with high nutrient demands from training.
What's Included
Preparation Required
Fasting for 8–10 hours is recommended for some nutrient tests but not all — check with your provider. Continue taking your regular supplements unless told otherwise (the test measures your steady-state levels). Morning draws are preferred for consistent results.
Biomarkers Tested
3Vitamin B9 (Folate) is crucial for DNA synthesis and repair. Low levels can lead to anemia and other health issues.
Essential for DNA synthesis, cell division, and red blood cell formation. Folate deficiency causes megaloblastic anemia and, during pregnancy, increases the risk of neural tube defects. Works closely with vitamin B12.
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.
