This action affects the preexamination variable since the incorrect amount of patient sample will lead to inaccurate results in the subsequent examination. It may also affect the examination variable if the incorrect amount of patient sample leads to inaccurate test results. However, it does not affect the postexamination variable since that pertains to activities that occur after the testing is complete.
