Ketamine Screening

This screening targets ketamine by detecting the substance and its primary metabolite, norketamine, in urine. Norketamine is produced as the body processes ketamine and may remain detectable for a longer period than the parent compound. The approximate detection window is two to four days, though individual variation may occur.

This test may be relevant for:

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

This test measures a single marker:

• Ketamine and its metabolites (primarily norketamine): measured in urine. Norketamine is the primary metabolite that the body produces after ketamine use. The approximate detection window is two to four days, though this may vary depending on individual factors.

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

If a positive result is obtained, confirmation testing may be performed using a more specific analytical method. The test provides information about detection or non-detection and does not indicate quantity 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 procedure is straightforward and typically takes only a few minutes.

This test may be considered when:

• A focused screening for ketamine is desired
• Personal insight into whether ketamine metabolites are present is wanted
• Documentation of a ketamine-specific screening result is needed

The result is reported as detected or not detected. A positive result suggests that ketamine 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 and hydration level may influence detection. Results should be interpreted in context and may be discussed with a healthcare provider if needed.

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. No other specific preparation is required.

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

If the initial screening produces a positive result, confirmation testing may be performed. The final report includes the confirmed outcome. A healthcare provider can help interpret the results in context if desired.
