QC Applications - Westgard QC - Blog - Page 3

We've asked the world about their QC, their IQCP, and their Six Sigma. Now we want to know about the quality control practices at the POC, near-patient, and/or rapid diagnostic testing.

(As is our tradition, several participants will randomly be selected to win a raffle prize: in this case, an early advance copy of the 2019 Poor Lab's Guide to the Regulations, to be published in early 2019.) Please, share your practices - and frustrations - with us about your point of care quality!

(Note: this survey is only open to operational laboratories, not for vendors or manufacturers)
