Dexedrine (Dextroamphetamine)
Use
The Dexedrine (Dextroamphetamine) test is utilized to monitor therapeutic levels and detect the presence of dextroamphetamine in plasma or serum samples. It is essential for individuals prescribed with Dexedrine for attention deficit hyperactivity disorder (ADHD) and narcolepsy, ensuring dosage is within the therapeutic range and preventing possible toxicity or abuse.
Special Instructions
Submit only 1 of the following specimens: Plasma: draw blood in a green-top (sodium heparin) tube(s), plasma gel tube is not acceptable. Spin down and send 5 mL sodium heparin plasma refrigerated in a plastic vial. Serum: draw blood in a plain red-top tube(s), serum gel tube is not acceptable. Spin down and send 5 mL of serum refrigerated in a plastic vial.
Limitations
Plasma or serum gel tubes are not acceptable and can lead to sample rejection. Hemolysis, lipemia, icterus, and other unspecified conditions are considered as potential causes for rejection. Minimum volume requirement of 2 mL is crucial to obtain clinically relevant results and avoid rejection due to insufficient volume.
