Neurofilament light chain (NfL) is a neuron-specific protein routinely released into the extracellular space. NfL levels rise above baseline in response to neuronal injury and neurodegeneration. Thus, NfL has been widely studied for various conditions ¹, and can be helpful for assessing patients for concussion recovery, Alzheimer’s Disease, and other neurodegenerative dementias.
