Vitamin B12 is crucial to your health. Do you get enough?

Vitamin B12 plays a key role in some of the body's most essential functions, from making red blood cells and DNA to supporting the nervous system. 


This Vitamin B12 Test measures the level of vitamin B12 (also called cobalamin) found in your blood. A vitamin B12 deficiency can cause fatigue, muscle weakness, intestinal problems, numbness, memory loss and anemia. If left untreated, a B12 deficiency may lead to irreversible nerve damage. Elevated levels of vitamin B12 may indicate health conditions such as liver disease or diabetes.

FAQ

  • Visit the Labcorp OnDemand website to browse and purchase laboratory tests and create your Labcorp OnDemand account. All Labcorp OnDemand testing requires a healthcare provider order; for your convenience, Labcorp OnDemand has contracted with PWNHealth LLC and its affiliated professional entities (collectively, PWNHealth) to provide healthcare provider services. Visit a Labcorp location for sample collection; or, if using an at-home kit, collect your sample yourself. We’ll let you know when your results are ready to be accessed through your Labcorp OnDemand account or through your Labcorp Patient account. 

  • Your results will be provided to you through our secure online portal to view or print. Results are also provided to PWNHealth, which provides professional healthcare provider services for OnDemand tests. If you are accessing your results through your Labcorp Patient account, all users linked to the account will have access to all OnDemand test results. Results may also be provided to a local, state, or federal health authority, but only when legally required. For example, many states require the testing laboratory and healthcare provider to report test results for certain communicable diseases, such as sexually transmitted diseases or COVID-19, to local or state health departments.
