External Quality Control (QC) procedure
The external Quality Control is one of the procedures that ensures the sys-
tem is operating within the specifications.
Note:
The Quality Control function must always be activated as a daily QC
measurement is mandatory when the instrument is clinically used.
A QC icon in the status bar on the screen indicates that a daily external
QC assessment is needed or that there are not any currently qualified
QC individuals who have completed their initial 4 qualification attempts.
The external Quality Control consists of two parts. One positive control from
a qualified staff member with a stable FeNO value providing a normal biolog-
ical FeNO sample and a negative control consisting of a NO free gas sample
automatically generated from ambient air.
NIOX VERO
®
will allow for one daily QC measurement that will not affect the
number of remaining tests on the NIOX VERO
®
Sensor. (During the first 20
days of instrument start-up, a maximum of seven QC testers can be qualified
without impact to the number of remaining tests on the Sensor.)
Note:
It is also possible to store the QC users in a database, see chapter
“6.7.6 Perform QC measurement” for information.
