This test measures the total level of folic acid (Vitamin B9) in your blood.
The folate blood test measures the total level of folic acid (Vitamin B9) in your blood. Folate (B9) breaks down homocysteine in order to create other chemicals your body needs. This test is important for assessing nutritional status and identifying potential deficiencies. It can help diagnose conditions related to folate deficiency, such as anemia and neural tube defects. Someone might take this test if they experience symptoms like fatigue, hair loss, or low mood, or if their doctor recommends it for monitoring health.

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.
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.
