Serum Vitamin B12 Test at Chughtai Lab

The Serum Vitamin B12 test is a blood test used to measure the level of vitamin B12 (cobalamin) in the bloodstream. Vitamin B12 is an essential water-soluble vitamin that plays a crucial role in red blood cell production, DNA synthesis, nerve function, and brain health. Adequate vitamin B12 levels are necessary for maintaining healthy blood cells and supporting the normal functioning of the nervous system. A deficiency can lead to anemia, neurological problems, and long-term complications if left untreated.

Vitamin B12 deficiency is relatively common and may occur due to poor dietary intake, malabsorption disorders, pernicious anemia, gastrointestinal surgery, long-term use of certain medications, or chronic medical conditions. Early diagnosis through a Serum Vitamin B12 test helps identify deficiencies before permanent nerve damage develops.

Doctors commonly recommend a Serum Vitamin B12 test for individuals experiencing persistent fatigue, weakness, numbness or tingling in the hands and feet, memory problems, difficulty walking, dizziness, pale skin, mouth ulcers, or unexplained anemia. The test is also used to evaluate nutritional deficiencies, monitor vitamin B12 replacement therapy, and assess patients with gastrointestinal disorders that impair nutrient absorption.

At Chughtai Lab, the Serum Vitamin B12 test is performed using advanced automated immunoassay analyzers to provide accurate and reliable results. Supported by experienced laboratory professionals, qualified pathologists, and rigorous quality assurance standards, Chughtai Lab delivers trusted vitamin deficiency testing through its nationwide network of collection centers across Pakistan.
