"We have a department supervisor that instructs the techs to delete (not omit) qc values outside of three s.d..Is there a specific CLIA rule against this? Where I come from, deleting qc values is wrong."

Another question coming in from one of our website members:
Could you give me some suggestions on establishing QC ranges for unassayed chem. Controls?
We currently use [Brand X] unassayed chem controls (much less in cost than assayed controls) for some of our chemistry analytes.
For these controls, we are provided a “target mean” and a range.
Occasionally, our established mean (i.e. n=30) for a new lot is outside of the range provided for “target mean” provided by manufacturer.
Could you suggest guidelines for acceptance of lab established means for unassayed controls?
Obviously, I would like to know how far from the “target mean” could the new lab established mean be?

We got the following question emailed to the website recently:
Greetings, I was [wondering] if the following case represents [violation] of 4 1s rule?
Control (A) point 1= EXCEEDS 2 SD /-2 SD lines >> warning
Control (A) point 2= WITHIN 2 SD/-2 SD lines >> accepted
Control (A) point 3= EXCEEDS 2 SD /-2 SD lines >> warning
Control (A) point 4= WITHIN 2 SD/-2 SD lines >> rejection
all the point[s] on the same side of the mean.
