Overall Assessment
Five substances tested in a single urine sample. None of the five was detected above the applied cut-off.
The analysis was carried out by LC-MS/MS. That is a confirmatory method: where an immunoassay rapid test cross-reacts with everyday medication, LC-MS/MS identifies the substance itself. A result from this method is therefore usable where a rapid test is not.
Key Findings
None of the five substances detected
GoodTHC-COOH, cocaine, amphetamines, opiates and benzodiazepines all fall below the method's cut-off.
Material: urine · Method: LC-MS/MS
InformationalLiquid chromatography coupled to tandem mass spectrometry. This method identifies the substance itself rather than reacting to it, so cross-reactions with common medication do not arise.
A result covers a window, not a moment
InformationalUrine testing shows use in the days before the sample was taken, not use at the moment of sampling. The window differs by substance and by pattern of use.
Detailed Analysis
Drug Screening
NormalAll five substances tested fall below the method's cut-off and are reported as not detected.
Indicative urine detection windows, strongly dependent on dose, frequency and individual metabolism:
THC-COOH — one to three days with occasional use, up to several weeks with daily use. Cocaine — two to four days. Amphetamines — two to four days. Opiates — one to three days. Benzodiazepines — several days for short-acting, up to several weeks for long-acting variants.
These windows are indicative. A not-detected result does not exclude use outside the window.
Recommendations
Keep the PDF as the document itself
The PDF report states the laboratory, the method, the sampling date and the substances tested. That is what an employer, occupational physician or authority generally wants to see. A screenshot of this overview is not.
Declare any medication in advance
Some prescribed medication falls within the substance groups tested — codeine-containing painkillers under opiates, prescribed sleep and anxiety medication under benzodiazepines. That is not a fault in the test; it is the reason to declare it beforehand.
Next Steps
No follow-up testing is required. This report is the result.
If it is unclear how this result relates to prescribed medication, discuss it with the prescribing doctor. This report is a laboratory result and not medical advice.

Drug Screening
5What It Measures
This test detects the presence of THC-COOH (11-nor-9-carboxy-THC), the primary urinary metabolite of THC. After cannabis use, THC is metabolised in the liver and its metabolites are excreted in urine over an extended period. The test provides a qualitative result indicating whether THC metabolites are present above the assay cut-off level. THC metabolites are lipophilic and accumulate in fatty tissue, which contributes to the potentially long detection window, particularly with regular use.
What It Measures
This test primarily detects benzoylecgonine, the main metabolite of cocaine, in urine. Cocaine itself is rapidly metabolised and has a very short half-life, but benzoylecgonine persists in the body for a longer period, making it the preferred target for urine screening. The test provides a qualitative result indicating whether benzoylecgonine is present above the assay cut-off level.
What It Measures
This test detects the presence of amphetamine-type substances and their metabolites in urine. The amphetamine class includes amphetamine, methamphetamine, and MDMA, among others. The test provides a qualitative result indicating whether these substances are present above the assay cut-off level. Immunoassay screening may show cross-reactivity with structurally similar compounds. Confirmatory testing can differentiate between specific amphetamine-type substances.
What It Measures
This test detects the presence of opiate compounds and their metabolites in urine. The primary targets are morphine and codeine, which are the principal metabolites of natural and semi-synthetic opiates. The test provides a qualitative result indicating whether opiate metabolites are present above the assay cut-off level. It is important to note that standard opiate immunoassays may not detect synthetic opioids such as methadone, fentanyl, or tramadol, which require specific targeted tests.
What It Measures
This test detects the presence of benzodiazepine compounds and their metabolites in urine. The benzodiazepine class includes numerous agents such as diazepam, alprazolam, lorazepam, and oxazepam. Immunoassay screening typically targets common metabolites shared among many benzodiazepines. Some newer benzodiazepines may have lower cross-reactivity with standard immunoassays, potentially requiring confirmatory testing for accurate detection.
