Amphetamines Urine Screen with Reflex to Quantitation
Also known as: AMP RFX U
Use
This test is useful for general screening in contexts such as compliance and abuse. It is designed to detect amphetamine exposure through a urine sample. A screen with reflex testing is the preferred method for ruling out amphetamine exposure due to its ability to provide both qualitative and quantitative results. For follow-up testing of a presumptive result, it is recommended to use the Amphetamines, Urine, Quantitative test (2010075).
Special Instructions
Not provided.
Limitations
Presumptive negative results for drugs and/or drug metabolites may indicate non-compliance, inappropriate timing of specimen collection relative to drug administration, poor drug absorption, diluted/adulterated urine, or limitations of testing. The concentration at which the screening test can detect a drug or metabolite may vary within a drug class, which is a limitation of testing. The test has not been cleared or approved by the US FDA and is only intended for clinical purposes.
