NEW TO ROUTINE LABORATORY TESTING?
Routine laboratory testing may be used for preventive screening, evaluation of symptoms, medication monitoring, management of chronic conditions, or follow-up of previous abnormalities.
There is no single laboratory panel that every person needs. Appropriate testing depends on factors such as age, medical history, family history, symptoms, medications, risk factors, and previous results. Understanding why a test was ordered, and how it fits into the larger clinical picture, is often more useful than focusing on an isolated number.
