Diluting QC

At my institution we usually use levels 1 and 3 for routine chemistry assays however one assay the level 3 falls above our AMR. We have decided to dilute that level for that assay instead of purchasing another QC level just for one assay. Does anyone else do this or has done this? is it acceptable practice?

Setting Medians of Prenatal Screening Tests with Low Testing Volume

The testing volume of prenatal screening dropped dramatically at our institution since 2020. Now we do <20 Quad screens and <100 first trimester screens per month in our lab. So now we have to look back a lot to assess medians of the prenatal screening tests, especially for African Americans. I wonder whether anyone has similar experience and how the problem is dealt with at your institution.

Seeking Suggestions to Screen EDTA Contamination

We have certain rule already built in our middleware to screen EDTA contamination. It only catches gross EDTA contamination cases with K>9.5 mmol/L. We'd like to adjust the rule to catch more EDTA contamination but not sure which cutoffs are more appropriate. Kind of balance between reporting real critical values in a timely manner while catching EDTA contamination. It will be greatly appreciated if anyone could share your experience and expertise.
