What is LC-MS confirmation testing?
LC-MS, or liquid chromatography-mass spectrometry, is considered the “gold standard” in analyte confirmation testing because it is the most accurate and sensitive way of detecting drugs of abuse and is admissible in a court of law. The liquid chromatographer is used to separate different compounds within a solution, while the mass spectrometer identifies the separated compound of interest by determining its mass and can even confirm the analytes empirical formula and molecular structure.


What is the difference between screening and confirmatory testing?
Drugs of abuse screening testing employs enzyme immunoassay (EIA) to convey to the technologist if the patient is positive or negative for a particular drug class; ex: opiates, amphetamines, benzodiazepines, etc. Screening tests are qualitative, meaning they distinguish whether a drug is present or not. Confirmatory testing uses liquid chromatography-mass spectrometry (LC-MS) to positively identify the exact drug present; ex: cocaine, alprazolam, oxycodone, etc. LC-MS assays are quantitative, meaning they also detect and calculate the drug concentration present in the patient’s system.


Why do patients sometimes test negative on screening tests but test positive on confirmatory tests?
This is not common, but can occasionally happen because the analyzer used to screen the patient’s urine has a cutoff value higher than the amount present in the patient’s urine. LC-MS instruments are exceptionally sensitive and can detect and quantify drug analyte concentrations lower than the screening analyzer’s cutoff values.


How is it possible that a patient can test positive on the screening test but negative on the confirmatory test?
Screening tests are not as sensitive or specific as confirmatory tests, so they can sometimes be subjected to interfering or cross-reacting substances, such as certain medications. Ex: Some patients that take the antidepressant Effexor occasionally test positive on their drug screen for PCP.
