QC question for Instrument users


Candybar

Recommended Posts

We recently acquired an Echo for our laboratory Blood Bank and were advised not only to do QC on the instrument but also at the bench. We are wondering what other instrument users do for QC purposes?

We would greatly appreciate your responses. Thanks in advance!

I would recommend QCing some reagents if you also perform testing on the bench. You are not just QCing the reagents, but also the cell washer, centrifuge, heat block, etc. What methodology are you using on the bench? Much of what has to be QC'd will be depend on whether you are using the same methodology or a different methodology.

We also do daily QC on our rack of tube testing reagents, for the same reasons as clmergen. Plus, it is our policy that the first time we report a pt's ABO/Rh type, the testing must be performed by two different techs or by two different methodologies. (So if there's only one tech in BB, she does the ABO/Rh testing by tube technique, and the Echo's ABO/Rh is our "second methodology".)

We use ProVue automation for routine testing but manual tube testing for STAT, trauma and as a backup when instrument is down. So we daily perform QC of reagents on instrument and manual tube test so that all equipment are also qced. cell washer, heat block etc.

Our blood bank technical specialist would like me to ask if it is a CAP or AABB requirement to do QC on the bench racks if you are QCing the reagents on the instrument. She feels it is redundant and a waste of resources. I thank you in advance for the answers you provide.

You are QC'ing your methodology along with the reagents. I don't know if it is spelled out in those terms but I would not tube test without QCing the reagents again in tube. And in our case, we sometimes have different lot numbers on the Echo than on the bench reagents so it would be required.

When you are doing QC by different methodology such as ProVue, MTS Gel or tube, you are QCing the reagents and your instrument or whole process.

Eg. If you run your QC on Provue and all qc passed that doesn't mean that if you run your test by MTS gel or Tube, all equipments are OK it will give same result.

SOmetime our ProVue QC is OK but when we run MTS gel QC we do get false positive reaction for our DAT because the MTS 2 reagent we use on the bench has contamination in it.

I do nto know this may be even CLIA requirement...
