Other Ancillary Tests

• Culture and Sensitivity: consider culture of oral/oropharyngeal mucosa or lesion if suspect infection (eg, fever, tender cervical adenopathy); must evaluate for aerobic, anaerobic, and fungal organisms

• CT /MRI: indicated if suspect tumor, evaluates extent of tumor size and involvement of adjacent structures; aids in staging and determining nodal status

• Laboratory Tests: complete blood count with differential, autoimmune and connective tissue profiles (eg, ANA, SS-A, SS-B, ESR, Rh factor, LE cell), ACE levels
