So what do you want to QC?

Whether the name on the blood sample bears any relation to the name of the 
patient from whom it was collected?
Whether the name on the blood sample bears any relation to the name on your 
LIS
Whether you actually get the right result at the "test-tube" stage?
Whether you actually report a result?
Whether you actually report the correct result?
Whether the report reaching the patient's bedside is the one you sent out?
Whether you're complying with local protocols?
Whether you're complying with national recommendations?

What you've asked is a good 2000+ word essay for a trainee. Perhaps you 
might like to be more specific in what you're asking.
