Determining the Right Drug Testing Panel

Drug tests are categorized into panels—typically 5, 10, or 12—indicating the number of substances screened. Custom options are also offered.

Understanding a Drug Test

A drug test involves technically analyzing a biological sample, such as urine, hair, blood, or saliva, to detect specific drugs or their metabolites. Key uses include identifying performance-enhancing drugs in sports, legal or parole screenings, and police sobriety checks, such as blood alcohol content (BAC) via breathalyzer. Various methods are available, differing in accuracy, sensitivity, and timeline. Additionally, tests might analyze illegal substances' chemical content to promote responsible use.

Does Secondhand Marijuana Smoke Lead to False Positives?

"Passive" exposure to marijuana smoke is typically excluded, as test thresholds are set above levels likely from passive inhalation. Certain urine sample anomalies can indicate false negatives or tampering. For example:

• Low creatinine may suggest excess water consumption or sample dilution.
• Creatinine, paired with specific gravity, assesses dilution; some labs dye toilet water to avoid sample tampering.
• Adding enzymes to samples for stability is a known attempt that often alters pH, which is also assessed.

Drug Elimination Timeline

The detection timeframe for drugs, known as the look-back period, varies based on several factors including:

• Drug quantity taken
• Frequency of drug use
• Type of drug used
• Individual metabolic rate and general health
• Fluid intake post-drug use
• Exercise level post-drug use
• Genetic differences affecting drug response
