Laboratory studies are performed as indicated clinically to identify genetic mutations associated with TSC, monitor anticonvulsant treatment, identify idiosyncratic or dose-related adverse effects, and identify or monitor underlying renal or pulmonary disease. Diagnosis should be possible in most cases using established clinical criteria. Molecular genetic testing is useful in uncertain or questionable cases, as well as for prenatal diagnosis and for screening family members of an affected individual.
