The present disclosure relates to a trackable precise-sample-injection device for a multi-well plate and, more specifically, to a trackable precise-sample-injection device for a multi-well plate, the device being capable of: preventing cross-contamination that can occur when many samples are manually put into a multi-well plate, and a diagnosis error caused by the injection of a sample into the wrong well or repeated injection; and simply recording and tracking information about wells into which samples are injected. The present disclosure relates to a trackable precise-sample-injection device for a multi-well plate, the device being capable of being efficiently used for a pooling inspection, and the like by injecting a plurality of samples into a multi-well plate.
