What is the purpose of this test?
The Vitamin B12 and Folate Blood Test Panel measures the levels of two essential nutrients—vitamin B12 and folate (vitamin B9)—in your blood. Both vitamins play critical roles in maintaining healthy red blood cells, supporting brain function, and preventing certain types of anemia. Low levels of vitamin B12 or folate can cause fatigue, weakness, memory problems, and even nerve damage if left untreated. This test helps identify deficiencies that could be affecting your energy, mental clarity, and overall health.
Vitamin B12 is vital for nerve function and producing red blood cells, while folate is necessary for cell division and the formation of DNA. This test is especially useful for detecting vitamin deficiencies that can be caused by poor diet, certain medications, or health conditions that affect nutrient absorption. By checking your B12 and folate levels, your healthcare provider can determine if supplements or dietary changes are needed to restore balance and improve your well-being.
Who should get this test?
- People who experience persistent fatigue or weakness
- Individuals with memory problems or trouble concentrating
- Those at risk of developing anemia
- People with a poor diet or digestive issues that may lead to vitamin deficiencies
- Vegans or vegetarians, as vitamin B12 is mainly found in animal products
- Individuals with conditions like Crohn’s disease or celiac disease, which affect nutrient absorption
- Pregnant women or women planning to become pregnant
