Organizations opt for CLIA waived home drug tests due to lower costs and ease of administration. Labs confirm positive results, saving on expenses.
Home drug tests use reagent strips to react with metabolites in urine. CLIA waived tests are simple and accurate for untrained users.
Lab drug tests use reagents and instruments for accuracy, confirming metabolite quantities for deducing drug use patterns.
Immunoassay in labs is detailed, with separated components for precise analyte binding, calibrated for accuracy.
Mass spectrometry bombards samples with electrons, measuring ionized fragments' mass; chromatography separates substances based on mobility in a fluid.
Lab testing with skilled technicians and expensive equipment is more accurate, but CLIA waived home tests suffice for many cases.
