The American Academy of Neurology (AAN) recommendations include measuring cobalamin (vitamin B12) and TSH levels of patients with suspected Alzheimer's disease to rule out other etiology. Any additional laboratory studies are ordered at the discretion of the physician, based on the individual needs of the patient.

The AAN does not recommend Lyme disease testing, BUN/Cr ratio assessment, or CRP measurement for patients in whom Alzheimer's disease is suspected.
