Neurology

From neuroimmunology to Alzheimer’s disease and dementia testing, neurological testing can help provide answers

Behind every sample is a life—a life filled with questions. We help provide answers with our broad menu of over 400 neurology tests, including a full portfolio for Alzheimer’s disease and dementia testing, as well as expansive testing for complex  neuroimmunological diseases and other neurological conditions.

Insights to help improve outcomes

The complexity of the neurological system and the absence of a specific clinical presentation make it difficult to know where to look first. In most cases, early detection and prompt therapy can improve patient outcomes.1 We offer a comprehensive neurological testing portfolio, including blood and CSF testing methods, so you can provide the answers and care your patients deserve.
