Abstract
A method for operating and diagnosing faults in a laboratory instrument comprising a plurality of subsystems may comprise performing an analytic sequence and a set of diagnostic steps. Such a method may be performed using a diagnostic reagent comprising paramagnetic particles and lacking an antibody component. Such a method may also include evaluating a set of the instrument's subsystems in the opposite of the order in which those subsystems are used during analysis.
Claims17
A method of operating and diagnosing faults in a laboratory instrument comprising a plurality of subsystems, the method comprising:
- a) performing an analytic sequence of steps to analyze a biological sample, wherein the analytic sequence of steps utilizes a set of subsystems from the plurality of subsystems of the laboratory instrument in a first order;
- and
- b) performing a set of diagnostic steps to identify faults in the laboratory instrument, wherein:
- i) performing the set of diagnostic steps comprises evaluating each subsystem in the set of subsystems in a second order;
- ii) the second order in which each subsystem in the set of subsystems is evaluated reverses the first order in which the set of subsystems are used in the analytic sequence of steps.
