Overview
Limited laboratory testing is recommended in most patients being evaluated for cognitive impairment and dementia. We do not order other laboratory tests unless there is a specific suspicion for abnormality. Other than the routine lab work for dementia, other laboratory tests are not recommended unless there is a specific suspicion for abnormality.[1][2]
Laboratory Findings
Routine lab work for dementias include:
- Complete blood count (CBC)
- Toxicology screening
- Liver function tests (LFTs)
- Calcium
- Blood urea nitrogen (BUN) / creatinine
- Glucose
- Thyroid function tests
- Vitamin B12 levels[3]
- Folate levels
- Infectious/inflammatory screenings
- HIV testing for suspected patients
- Rapid plasma reagin (RPR) testing for those patients suspected of having syphilis
Electrolyte and Biomarker Studies
