Amphetamines Analysis, Serum
Use
The Amphetamines Analysis, Serum test is performed to detect amphetamines in serum samples. Amphetamines are central nervous system stimulants used for therapeutic purposes including treatment of attention-deficit hyperactivity disorder (ADHD) and narcolepsy, as well as for illicit use. Detection and confirmation of amphetamines in serum samples can be important for both clinical and forensic purposes, particularly for assessing possible overdose or drug abuse.
Special Instructions
A positive result in the screening test will trigger a reflex to a confirmation test, specifically Amphetamines, Rfx (FASCR), which will incur an additional charge. Serum gel tubes are not acceptable for this test; only plain red-top tubes are to be used for blood collection.
Limitations
The test's accuracy can be affected by the presence of interfering substances, such as other drugs or compounds in the serum that may cause cross-reactivity. False positives or negatives are possible, so confirmatory testing is performed if the initial screen is positive. Additionally, detection of amphetamines does not necessarily correlate with clinical impairment or constitute legal intoxication. Variability in individual metabolism and adherence to dosing regimens can also impact serum levels.
