Hi David
There's no misunderstanding of the role/definition of EQA
However there is a supposition that blood gas EQA is not an EFFECTIVE OR TIMELY provider of assurance or tool for quality management.
Ideally we would have an independent QC material with stated values.
We would use this more, use EQA less and reflect on what real value EQA delivers in the context of blood gases.
The point being that EQA scheme manufacturers may be in a position to provide both sorts of material.....and/or support labs in both.
Regards
Kathy
