Amphetamines, Screen With Reflex Confirmation, Serum
Also known as: Amphetamine, Methamphetamine
Use
Detect the presence of amphetamine class drugs.
Special Instructions
If a reflex test is performed due to a presumptive positive result, additional charges and CPT code(s) will apply. Serum should be separated from cells within two hours of venipuncture and submitted in a plastic transport tube.
Limitations
The test initially uses a presumptive screening method by immunoassay, which may detect other substances; therefore, confirmed identification of specific compounds is critical following a positive screen. The chromatography mass spectrometry (GC/MS or LC/MS-MS) confirmation is limited to the quantitation of amphetamine-class compounds present at or above the limit of quantitation.
