The decision to perform any laboratory or imaging evaluations is based on the need to confirm the diagnosis and to rule out other potentially life-threatening illnesses. Sometimes certain investigations are needed to provide appropriate and safe medical or surgical treatment. The recommended treatment should be based on clinical findings or changes in examination findings.

Extreme care should be taken during diagnostic testing for chronic pain syndrome (CPS). Carefully review prior testing to eliminate unnecessary repetition.

Routine complete blood count (CBC), urinalysis, and selected tests for suspected disease are important. Urine or blood toxicology is important for drug detoxification, as well as opioid therapy.
