An inconclusive result in drug testing indicates that the laboratory is unable to definitively confirm or deny the presence of specific substances above the established threshold. This outcome stems from various factors, such as a sample with insufficient quantity for analysis, technical issues during the testing process, or results falling within a gray area near the cutoff level. A sample flagged as such does not confirm drug use. For example, a test may return an “inconclusive” result if the creatinine level in the urine is too low, suggesting dilution, which hinders accurate analysis.
The proper interpretation of drug test results is critically important, particularly in employment, legal, and athletic contexts. An incorrect classification can have severe ramifications, affecting an individual’s career, legal standing, or athletic eligibility. Historically, ambiguous test results may have been treated inconsistently, leading to potential unfairness. Modern standards and guidelines emphasize the need for retesting, further investigation, or alternative testing methods when initial results are not definitive.
