No sensitive or specific blood or urine tests are currently available for DLB. Laboratory studies in patients with dementia with Lewy bodies (DLB) should include those usually ordered in a dementia evaluation, including the following:

  • Chemistry panel

  • Complete blood count (CBC)

  • Thyroid studies

  • Vitamin B-12 levels

  • Syphilis, Lyme disease, or human immunodeficiency virus (HIV) testing, when appropriate
