To shorten the processing time required for sample inspection processing including sample measurement and sample preparation, a blood sample testing apparatus may include: a blood-cell-count measurement unit that performs measurement of a blood sample stored in a sample container positioned in a first position; a smear preparation unit that prepares a smear of the blood sample stored in the samplecontainer positioned in a second position; and a transport unit that transports the sample container from the first position to the second position and from the second position to the first position.
