Service Providers for Vitamin B-12
The Vitamin B-12 test measures the level of vitamin B-12 in the blood, which is essential for nerve function, DNA production, and red blood cell formation. Low levels of B-12 can lead to anemia, nerve damage, and cognitive issues. A blood sample is drawn for the test. No special preparation is typically required. Risks include mild discomfort during the blood draw. Low vitamin B-12 levels may indicate a deficiency due to poor diet, malabsorption, or certain medical conditions. High levels may indicate liver disease or certain types of cancer. Normal activities can be resumed after the test.
