Amphetamine Screening

This screening detects amphetamines and related compounds in urine. The approximate detection window is two to four days, though this may vary depending on individual factors such as metabolism, hydration, and dosage. It is worth noting that certain prescription medications, including some used for ADHD, may contain amphetamine-based compounds and could produce a positive screening result.

This test may be relevant for:

• Individuals who wish to verify the presence or absence of amphetamines for their own information
• People who need a focused, single-substance screening for amphetamines
• Anyone seeking documentation of an amphetamine-specific screening result

This test measures a single marker:

• Amphetamines: measured in urine, expressed in ug/l. The test detects the presence of amphetamine and related compounds above the laboratory's reporting threshold. The approximate detection window is two to four days. Note: some prescription medications (such as certain ADHD medications) contain amphetamine-based compounds and may produce a positive result.

A positive result indicates that amphetamines were detected above the laboratory's reporting threshold, suggesting that the substance may have been present in the body within the detection window. A negative result means that amphetamines were not detected above the threshold at the time of sample collection.

If a positive result is obtained, confirmation testing may be performed. It may be relevant to mention any prescription medications to a healthcare provider, as some medications can influence the screening outcome. The test provides information about detection or non-detection and does not indicate dosage or frequency of use.

The test requires a urine sample, collected at a certified sample point (afnamepunt). A mid-stream sample is collected under the guidance of trained personnel. The process is straightforward and typically takes only a few minutes.

This test may be considered when:

• A focused screening for amphetamines is desired
• Personal insight into whether amphetamines are present is wanted
• Documentation of an amphetamine-specific screening result is needed

The result is reported as detected or not detected. A positive result suggests that amphetamine use may have occurred within the approximate detection window (two to four days). A negative result indicates that the substance was not found above the reporting threshold.

Individual factors such as metabolism, hydration, and prescription medication use may influence the result. If you take prescription medications that contain amphetamine-based compounds, this information may be relevant when discussing results with a healthcare provider.

Collect a mid-stream urine sample at the sample point. Hydrate normally beforehand. Over-hydration may dilute the sample and could affect the reliability of the result. If you take prescription medications that could affect the screening, you may wish to note this for reference when discussing results with a healthcare provider.

Results are typically available within a few working days. The report indicates whether amphetamines were detected or not detected.

If the initial screening produces a positive result, confirmation testing using a more specific analytical method may be performed. The final report includes the confirmed outcome. A healthcare provider can help interpret the results in context, particularly if prescription medications may have influenced the screening.
