External Quality Assessment
Quality Club
Control charts give information about the precision and the pattern of variation
within a laboratory, but they give little information about trueness and no
information about the performance of a laboratory in relation to other
laboratories. To obtain such information the same samples are assayed by
laboratories using the same type of testing.
If the internal quality control shows low variation of results on a constant level,
this means the analytical procedure is stable. By comparing the concentration
levels obtained in the external quality assessment program, it is possible to judge
the accuracy of the measurements in the laboratory.
Once low variation and good accuracy have been established for the analytical
procedure, it is essential to continuously monitor the performance using internal
and external quality control programs in order to maintain high-quality results.
Quality Club is an international quality assessment program for laboratories
using Phadia 100, Phadia 250 or Phadia 1000 for
in vitro
allergy, asthma and
autoimmunity testing. Today, more than 800 testing laboratories are active club
members. There are four programs in Quality Club which are similar: Specific
IgE and Total IgE, ECP and EliA Autoimmunity. Each program kit contains
reagents and material for four month use. It includes numbered control samples,
result cards, addressed envelopes and Directions for Use. Everything is distrib-
uted to the members.
Quality Club members can register their results directly on the Extranet and also
download reports through the Extranet. All that is needed is a username and a
password. For access to Extranet, please contact Phadia AB.
