Abstract
In the prior art, the reliability of a measurement result is lowered by the deterioration of an ISE reagent remaining in a flow passage in the standby time of an electrolyte analysis unit. To solve this problem, when receiving an instruction to measure a patient sample requiring measurement using an electrolyte analysis unit 8, this automatic analysis device 1 determines deterioration of a residual reagent remaining in the flow path of the electrolyte analysis unit prior to measurement of the patient sample when the standby time of the electrolyte analysis unit is equal to or greater than a predetermined time.
Claims15
An automatic analyzer comprising:
- an electrolyte analysis unit that measures an electrolyte concentration by an ion selective electrode method and can measure at least a chloride ion concentration;
- and
- a control unit,
- wherein, on receipt of an instruction to measure a patient sample that requires measurement using the electrolyte analysis unit, the control unit determines, when a standby time of the electrolyte analysis unit is equal to or longer than a predetermined time, deterioration of a residual reagent remaining in a flow path of the electrolyte analysis unit prior to the measurement of the patient sample.
A measuring method for a patient sample using an automatic analyzer including an electrolyte analysis unit that measures an electrolyte concentration by an ion selective electrode method and can measure at least a chloride ion concentration, and a control unit,
- the measuring method comprising:
- causing the control unit to measure, on receipt of an instruction to measure a patient sample that requires measurement using the electrolyte analysis unit, a standby time of the electrolyte analysis unit;
- and
- causing the control unit to determine deterioration of a residual reagent remaining in a flow path of the electrolyte analysis unit prior to the measurement of the patient sample when the standby time of the electrolyte analysis unit is equal to or longer than a predetermined time.
