A B12 level of 1262 picograms per milliliter (pg/mL) is considered elevated, as normal levels typically range from about 200 to 900 pg/mL, depending on the lab. High B12 levels can occur due to various factors, including excessive supplementation, liver disease, or certain types of blood disorders. It's important to consider symptoms and other clinical evaluations, so discussing the result with a healthcare provider is recommended for proper interpretation and guidance.
