About this test
Vitamin B12 Test
The Vitamin B12 Test is an important blood test used to measure the level of Vitamin B12 (Cobalamin) in the body. Vitamin B12 is an essential nutrient required for healthy nerve function, red blood cell production, DNA synthesis, and proper brain function.
Low Vitamin B12 levels can lead to serious health problems such as megaloblastic anemia, fatigue, nerve damage, memory problems, weakness, and neurological disorders. Since the body cannot produce Vitamin B12 naturally, it must be obtained through diet or supplements. This test helps detect deficiency early so treatment can begin promptly.
The Vitamin B12 test is commonly recommended when patients show symptoms of deficiency or when nutritional assessment is required.
