For example, ethanol is determined as ethyl glucuronide, while cocaine use is confirmed using ecgonine. Testing for metabolytes reduces the likelihood of false positive results due to contamination. At its core, a drug screen consists of a testing method called the enzyme multiplied immunoassay technique (EMIT).

The confirmation test in most laboratories is it safe to mix antibiotics and alcohol (and all SAMHSA certified labs) is performed using mass spectrometry, and is precise but expensive.

- Compared with a urine test, a blood test is more accurate in determining the concentration of a particular drug.
- But if rescheduling were to occur without other legislative amendments, state-level recreational or medical marijuana use would still remain illegal under federal law.
- Drug testing detects the presence or absence of a drug or its metabolites in a biological sample.
The detection window varies depending on whether the test is done with a sample of urine or hair. It can also depend on whether someone is a chronic or occasional user of the drug. A negative result indicates that the drugs tested for are not present or are not present in a high enough quantity to detect. It does not indicate that the person has never used the drugs or that they will not use the drugs in the future. A positive result indicates that the drug or its byproducts are present in the person’s system in detectable amounts.
It usually takes two hours before a substance can be detected in the urine. Factors like urine pH and fluid intake can have an impact on the results. Urine is the most well-established matrix and is the most commonly used matrix for point-of-care testing (POCT).
