Hello,
Per the package insert for Direct Chek Hemochron controls Accriva "recommends that each institution establish its own expected range of response based on the mean +/- 2 SD of at least 20 repeated test results." Is anyone doing this? That's more than one box of QC. If not, what are you doing for CAP POC.07456 - The laboratory establishes or verifies an acceptable control range for each lot of control material? Thank you.

As most Hemochron users know, achieving acceptable QC values with DirectChek is extremely technique dependent and is often difficult for POC users to attain, even using the manufacturer's range. A repetitive analysis range defined and set by the POCC would likely result in a much narrower range for the POC staff to have to achieve and quite possibly an impossible goal, or at the very least, lots of wasted QC. I could not see the value, especially when it has very little bearing on how patient samples are handled.
