Integrated sample processing system with multiple detection capability
An integrated sample processing system including an analyzer and a mass spectrometer is disclosed. The integrated sample processing system can perform multiple different types of detection, thereby providing improved flexibility and better accuracy in processing samples. The detection systems in the sample processing system may include an optical detection system and a mass spectrometer.
1 . A method performed by sample processing system comprising an analyzer, a mass spectrometer, and a shared control system,
wherein the shared control system is operatively coupled to and is configured to coordinate a sample transfer between the analyzer and the mass spectrometer:
performing, by the analyzer, analysis for a drug and/or drug metabolite in a first processed sample aliquot derived from a first sample aliquot of a sample in a reaction vessel;
determining, whether a concentration of the drug and/or drug metabolite in the first processed sample aliquot is below, above, or equal to a predetermined threshold; and
performing, by the mass spectrometer, a secondary analysis for a drug and/or drug metabolite in a second processed sample aliquot derived from a second sample aliquot of a sample in a reaction vessel when the concentration is above or equal to a predetermined threshold.
2 . The method of claim 1 , wherein the first processed sample aliquot and the second processed sample aliquot are derived from a single primary sample.
3 . The method of claim 1 , wherein a primary analysis of a drug is performed by an immunoanalyzer or a chemical analyzer.
4 . The method of claim 3 , wherein the chemical analyzer uses photometry to determine the concentration of the drug or drug metabolite in the first processed sample aliquot.
5 . The method of claim 3 , wherein the immunoanalyzer uses an immunoassay to determine the concentration of the drug or drug metabolite in the first processed sample aliquot.
6 . The method of claim 1 , wherein a positive report is generated when both the primary analysis and the secondary analysis indicate the presence of the drug or the drug metabolite.
7 . The method of claim 1 , wherein performing, by the analyzer, analysis for a drug and/or drug metabolite in the first processed sample aliquot derived from the first sample aliquot of the sample in the reaction vessel further comprises:
dispensing reagents into the reaction vessel containing the first sample aliquot;
incubating, the reaction vessel containing the reagents and the sample aliquot; and
separating, the analyte from the other components in the first sample aliquot using a washing and a separation process.
8 . The method of claim 7 , wherein the separation process comprises a magnetic separation process.
9 . The method of claim 1 , wherein the analyzer is a mass spectrometer for the step of: performing, by the analyzer, analysis for a drug and/or drug metabolite in a first processed sample aliquot derived from a first sample aliquot of a sample in a reaction vessel.
10 . The method of claim 1 , wherein the predetermined threshold is a detectable presence of the drug and/or drug metabolite in the first processed sample aliquot.
11 . The method of claim 1 , wherein the drugs are drugs of abuse including amphetamine, barbiturates, benzodiazepines, opiates, oxycodone, cocaine, methadone, EDDP, THC, and buprenorphine.
12 . The method of claim 1 , wherein the sample comprises urine, blood, spinal fluid or oral fluid.
13 . The method of claim 1 , wherein the analyzer comprises: a sample pipetting station, a bulk vessel feeder, a first reagent pipetting station, a second reagent pipetting station, a reaction vessel transport device, an incubator/wash/read station, a sample storage, and a reagent storage.
14 . The method of claim 13 , wherein the reaction vessel transport device comprises a pick-and-place gripper.
15 . The method of claim 13 , wherein the sample storage comprises a precision controlled refrigerator with multiple storage locations configured to receive and transfer reaction vessels.
