Vitamin B12 Test

A Vitamin B12 test is a blood test that measures the levels of vitamin B12 in the body. Vitamin B12 is an essential nutrient that plays a critical role in the production of red blood cells, proper nerve function, and DNA synthesis.

A Vitamin B12 deficiency can cause symptoms such as fatigue, weakness, tingling, or numbness in the hands and feet, and difficulty maintaining balance. It can also lead to anaemia and damage to the nervous system. Vitamin B12 deficiency can occur in people with pernicious anaemia, gastrointestinal disorders, and some autoimmune diseases.

The Vitamin B12 test is typically performed on a blood sample, and results are usually available within a few days. It can help diagnose a vitamin B12 deficiency, monitor treatment progress, and assess the risk of complications.

If you are experiencing symptoms of a vitamin B12 deficiency or have a condition that puts you at risk for it, it's important to talk to your healthcare provider about getting tested. Early detection and treatment can help prevent serious complications.
