About this test
Vitamin B12 (Cyanocobalamin) test measures the level of vitamin B12 in the blood to assess nutritional status and detect deficiency affecting nerve function and red blood cell formation.
The Vitamin B12 (Cyanocobalamin) test is used to determine the amount of vitamin B12 in the blood. Vitamin B12 is an essential water-soluble vitamin that plays a key role in red blood cell formation, nerve function, and DNA synthesis.
A deficiency of vitamin B12 can lead to anemia, fatigue, weakness, memory problems, and nerve-related symptoms such as tingling or numbness. It is commonly seen in individuals with poor dietary intake, malabsorption conditions, or certain medical disorders affecting the stomach or intestines.
This test is widely used to diagnose vitamin B12 deficiency, evaluate anemia, and monitor patients receiving supplementation. It is also helpful in assessing overall nutritional status and neurological health.
Test Recommended For
- Individuals with fatigue, weakness, or pale skin
- Patients with suspected anemia
- Individuals with tingling, numbness, or neurological symptoms
- People with poor dietary intake (e.g., vegetarians/vegans)
- Patients with malabsorption disorders
- Monitoring vitamin B12 therapy
