The Drugs of Abuse – 9 Drugs Panel test is a diagnostic test that screens for the presence of nine commonly abused drugs in the body. The test checks for the presence of amphetamines, barbiturates, benzodiazepines, cocaine, marijuana, methadone, opiates, phencyclidine (PCP), and propoxyphene. This test is usually performed on individuals who have a history of drug abuse, those suspected of drug abuse, or those who are in treatment for drug addiction. The test is typically conducted on urine samples, although blood or hair samples can also be used. The test is highly sensitive and specific, allowing for accurate detection of these drugs in the body. Results of the test can aid in the diagnosis of drug abuse, monitor the effectiveness of drug addiction treatment, and help individuals on the path to recovery.
