Drug screening tests are designed to detect the presence of illegal or prescription drugs in a person's system. These tests typically look for common substances such as marijuana, cocaine, amphetamines, opioids, and PCP. The purpose is to identify drug use for various reasons, including: - Employment screening - Medical diagnosis and treatment - Legal or forensic purposes - Monitoring individuals in drug rehabilitation programs - Athletic competition compliance Results are usually reported as positive (presence of drugs detected) or negative (no drugs detected). Positive results may require further confirmatory testing to identify specific substances and their concentrations.
A ‘low’ or negative result in a drug screening test indicates that no illicit drugs or their metabolites were detected in the sample at levels above the test’s cutoff threshold. This suggests:
However, a negative result does not definitively prove absence of drug use, as some substances may not be included in the panel or might be present below detectable levels.
A ‘high’ or positive result in a drug screening test indicates that one or more illicit drugs or their metabolites were detected in the sample above the test’s cutoff threshold. This suggests:
It’s important to note that positive results from initial screenings are often followed up with more specific confirmatory tests to rule out false positives and identify the exact substances present. Interpretation should consider prescribed medications and other factors that might influence results.
