Vitamin B12 + Folates LabCorp

What is this test?

The Vitamin B12 Plus Folate Test can help diagnose central nervous system disorders, anemia, and issues with nutrient absorption.

B12 and folic acid are important in maintaining muscle strength and energy levels, and B12 also plays an important role in maintaining your mood. The body doesn’t produce these nutrients, which means we have to obtain them through diet and supplementation. Low levels of B12 and folic acid can indicate anemia or problems absorbing the nutrients. It can also indicate neuropathy, or nerve disorders.

Who is this test for?

This test can help diagnose a deficiency in B12 and folate, which can lead to anemia and symptoms like lack of energy, fatigue, numb extremities, muscle weakness, affected vision, and others.  This test can also indicate a potential nerve disorder (neuropathy). If you are experiencing nerve issues like numbness and tingling (a “pins and needles” sensation), throbbing or burning pain in your extremities, or sensitivity to touch, this test can help identify whether these symptoms stem from neuropathy.
