1. A medical analyzing system configured to insure that an operator has completed training to operate the medical analyzing system and that patients' blood samples are properly prepared, the medical analyzing system comprising: a server and a hematology analyzer in communication with the server via a network, the hematology analyzer further comprising: a display, a processor, and measurement hardware further comprising: a pipette configured to draw each of the patients' blood samples from each of corresponding sample vials, a chamber configured to mix the patients' blood samples drawn by the pipette and a reagent, and a detector configured to detect a signal of each blood cell contained in the mixed patients' blood samples, wherein the processor is programmed to: start the hematology analyzer; output, via the display, a screen image before measuring the patients' blood samples requesting the operator to input confirmation regarding whether the operator is trained in using the hematology analyzer; receive, via the screen image, a response regarding whether or not the operator is trained in using the hematology analyzer; when the response indicates that the operator has failed to complete the training, prevent measurement of the patients' blood samples by the measurement hardware by powering off the hematology analyzer, or outputting, via the display, the screen image again, and when the response indicates that the operator has completed the training, request, to the server, a confirmation whether the operator has completed the training and communicate the confirmation from the server back to the hematology analyzer to allow the measurement hardware to further perform a quality check; output, via the display, after the operator has completed the training, instructions to run the quality check on a first sample vial; when the first sample vial has failed the quality check once, output, via the display, instructions to rerun the quality check on the first sample vial; when the first sample vial has failed the quality check more than once, output, via the display, instructions to select a new first sample vial and rerun the quality check; when the first sample vial has passed the quality check, output, via the display, instructions to run the quality check on a second sample vial; when the second sample vial has failed the quality check once, output, via the display, instructions to rerun the quality check on the second sample vial; when the second sample vial has failed quality check more than once output, via the display, instructions to select a new second sample vial and rerun the quality check; when the second sample vial has passed the quality control check subsequent to the first sample vial also passing the quality control check, perform the measurement of the patients' blood samples.
