TY - CHAP M1 - Book, Section TI - Interpretation of Common Laboratory Tests A1 - Rosenberg, Eric A2 - Salardini, Arash A2 - Biller, José PY - 2016 T2 - The Hospital Neurology Book AB - Diagnostic testing is used to evaluate symptoms or abnormal physical examination findings. Testing should be ordered to assess the severity or stability of a medical problem or to evaluate an abnormal symptom or sign detected during a medical interview and examination. Routine testing or repeated testing of asymptomatic individuals with previously normal test results does not accurately predict which patients will develop complications but it does increase resource use and healthcare costs.
