Impact of point-of-care testing on healthcare delivery.

rent insights on functional sensitivity is not so much whether the 15%, 20%, or 30% interassay CV should have been chosen, but rather concerns the necessity for manufacturers and laboratories to use the same clinically relevant protocol for establishing interassay precision when comparing assays [3]. Further, because functional sensitivity varies across laboratories that are using the same manufacturer’s platform, perhaps as a reflection of instrument differences, it is essential that laboratories establish their functional sensitivity limit independent of the manufacturer’s claims and monitor it on an on-going basis [3/.
