A method of washing an aspiration probe of an in-vitro diagnostic system is disclosed. The aspiration probe comprises an outer surface and an inner surface forming an inner space for receiving a fluid. The method comprises dipping the aspiration probe into a first wash fluid so that the outer surface is immersed at least in part into the first wash fluid, aspirating an amount of the first wash fluid into the inner space of the aspiration probe, propagating an ultrasonic vibration to the outer surface of the aspiration probe via the first wash fluid, and rinsing the outer surface and the inner surface of the aspiration probe with a second wash fluid. Further, an in-vitro diagnostic method and an in-vitro diagnostic system are disclosed.

The automatic analyzer includes: a liquid dispensing mechanism that performs suction of a liquid; a pressure sensor that measures a change of an internal pressure of a probe provided at the liquid dispensing mechanism; a determination section that determines whether the suction of the liquid by the probe is normal suction or air suction abnormality; an analysis section; a storage section that stores a cumulative number of times of air suction abnormality per liquid and an allowable cumulative number for the cumulative number of times of air suction abnormality; and a controller that exercises operation control over the liquid dispensing mechanism, the determination section, and the analysis section. The controller exercises control such that the cumulative number of times of air suction abnormality is updated and the updated cumulative number is stored in the storage section even if the air suction abnormality occurs non-consecutively.
