14. An in-vitro diagnostic method comprising:
receiving a test medium including a test object;
acquiring an expiration date of the test medium;
determining whether the expiration date of the test medium has passed, based on first time information that is set as a standard clock time and used for determining whether the expiration date of the test medium has passed; and
analyzing the test object based on second time information that is set as an arbitrary time, in response to determining that the expiration date of the test medium has not passed according to the first time information.
15. The in-vitro diagnostic method of claim 14 , further comprising:
outputting an informing signal indicating that the expiration date of the test medium has passed, in response to determining that the expiration date of the test medium has passed according to the first time information.
