Understanding your B12 and folate levels is essential for maintaining energy, cognitive function, and overall health. These nutrients play key roles in red blood cell production and nervous system function. Testing your levels can help identify deficiencies and guide personalized nutrition or supplementation plans.

Test Description

This Vitamin B12 and Folate Test checks the levels of folate and vitamin B12, two important nutrients your body needs to work properly. Folate helps your body make and repair cells, especially DNA, and is important for growth and development. Vitamin B12 is necessary for healthy nerves, making red blood cells, and keeping your brain working well.

The test is useful because it can find low levels of these nutrients before they cause serious problems. If folate or vitamin B12 levels are too low, it can lead to anemia, which makes you feel tired and weak, or problems with your nerves, like tingling or trouble remembering things. These deficiencies can happen for different reasons, such as not eating enough of the right foods, certain health conditions that make it hard to absorb nutrients, or medications that interfere with absorption.

By checking these levels, the test helps identify whether you need to make changes, like adjusting your diet, taking supplements, or getting further medical care. It is especially helpful for people with symptoms like fatigue or nerve issues, those with specific health conditions, or people at higher risk, like vegans, older adults, or pregnant women. Regular testing can help keep these nutrient levels where they need to be for good health.

Markers

• Folate: A type of B vitamin that helps your body make new cells, including red blood cells. It’s also important for brain function and healthy growth, especially during pregnancy.
• Vitamin B12: Another B vitamin that supports red blood cell production, keeps your nervous system working properly, and helps your body create energy from food.

Who Should Consider This Test?

• Pregnant women: Folate testing is vital for ensuring sufficient levels of this B vitamin, which supports the formation of the baby’s neural tube, reducing the risk of birth defects like spina bifida and anencephaly, especially in the early weeks of pregnancy.
• People with anemia: Folate and vitamin B12 are essential for producing healthy red blood cells; a B12 and folate lab test can help diagnose the type of anemia, such as megaloblastic anemia, and guide treatment to address symptoms like severe fatigue, lightheadedness, and pale skin.
• Older adults: Testing for vitamin B12 is especially important in this group, as absorption naturally decreases with age due to reduced stomach acid or medications, and deficiencies can cause symptoms like nerve tingling, memory loss, or unsteady walking.
• People with digestive conditions: Conditions like celiac disease, Crohn’s disease, or a history of gastrointestinal surgeries can impair the body’s ability to absorb folate or vitamin B12, leading to deficiencies that may result in fatigue, weight loss, or neurological problems.
• Vegans or vegetarians: Since vitamin B12 is almost exclusively found in animal products, people following plant-based diets may not get enough from food alone, and regular testing can confirm whether supplementation or fortified foods are needed.
• People with neurological symptoms: Symptoms like numbness, tingling in the hands and feet, memory problems, or difficulty concentrating could be linked to vitamin B12 deficiency, making testing critical for diagnosing and preventing long-term nerve damage.
• People with alcohol use disorder: Chronic alcohol consumption can interfere with the absorption and storage of folate, and testing can help identify deficiencies that may contribute to poor health outcomes, including anemia and cognitive issues.
• People with chronic fatigue or weakness: Persistent tiredness and a lack of energy can sometimes be traced to low levels of folate or vitamin B12, and testing helps uncover nutrient-related causes for these symptoms.
• People with a family history of deficiencies: A history of vitamin B12 or folate-related conditions in close relatives could indicate a genetic predisposition, such as mutations in the MTHFR gene, that impairs folate metabolism or vitamin B12 absorption.
• People taking certain medications: Medications like metformin for diabetes or proton pump inhibitors for acid reflux can block the absorption of vitamin B12 over time, making testing essential for those using these drugs regularly.
• People preparing for or recovering from surgery: Testing folate and vitamin B12 levels is especially important before or after gastrointestinal surgeries, such as bariatric surgery, to ensure the body has enough nutrients for proper recovery and wound healing.
• People with mood changes or depression: Low folate or vitamin B12 levels can be associated with mental health changes, including low mood, irritability, or depressive symptoms, and testing can help determine if supplementation could improve these conditions.
• Infants or children with developmental delays: A B12 and folate lab test can reveal whether vitamin B12 or folate deficiencies are contributing to growth issues, delayed milestones, or learning difficulties, allowing for timely intervention.
• People with autoimmune conditions: Autoimmune disorders, such as pernicious anemia or lupus, can impair the absorption or utilization of vitamin B12 or folate, and testing is crucial for monitoring and managing these conditions effectively.
