The Vitamin B12 Test measures blood levels of vitamin B12, a vital nutrient essential for nerve function, red blood cell production, and DNA synthesis. Low B12 levels can cause fatigue, weakness, neurological issues, and anaemia. It helps diagnose vitamin B12 deficiency, pernicious anaemia, and malabsorption disorders such as celiac or Crohn’s disease. This test aids in the monitoring of supplementation therapy or dietary intake, especially in vegans, the elderly, or people with gastrointestinal surgeries. The blood sample is usually taken without special preparation. Maintaining optimal B12 levels supports cognitive health and energy metabolism. Redcliffe Labs provides home collection by certified phlebotomists and delivers accurate reports promptly to support the management of metabolic and neurological health. Read less
