keeping logs of quality control is important because

• AAHA requirement

• detect trend/shift in values

  • helps with repair

commercially prepared control samples

• run just like a patient sample

• have an acceptable range of values

  • mean value of ± 2 standard deviations

keep maintenance logs on machines

• if you calibrate it

• change or fix something
