additional
reagents.
Each
device
contains
a
full
complement
of
reagents
that
are
required
to
perform
the
immunoassay.
The
Quidel
Triage
tests
have
been
designed
to
include
assay
controls
in
each
test
device
that
monitor
the
assay
procedure
and
the
reagent
integrity.
The
assay
controls
present
a
unique
and
valuable
extension
to
the
traditional
approach
to
quality
control
using
liquid
reagents.
If
the
product
is
stored
under
specified
conditions,
proper
functioning
of
the
assay
controls
indicates
that
the
test
device
is
valid
and
proper
adherence
to
assay
protocol
has
been
followed.
The
assay
controls
in
the
Quidel
Triage
tests
require
the
need
to
re
Ͳ
think
the
frequency
with
which
external
quality
control
specimens
should
be
tested.
The
Quidel
Triage
tests
have
been
designed
to
yield
long
Ͳ
term
reagent
stability.
In
addition,
the
system
provides
quality
control
parameters
in
three
separate
and
distinct
categories:
Internal
device
controls
Meter
electronic
controls
Software
controls.
The
combination
of
these
quality
control
features
provides
more
information
about
the
validity
of
each
assay
than
can
be
provided
by
the
more
traditional
methods
of
reagent
and
assay
procedure
validation.

The
Internal
Control
Zones
are
built
Ͳ
in
functional
immunoassays.
This
control
verifies
that
the
device
functioned
properly
and
that
the
assay
was
correctly
performed.
The
Internal
Positive
Control
Zone
ensures
that
the

the

the

and
the

are
functioning
properly.
The
manufacturer
sets
acceptable
ranges
for
the
control

for
each
lot
of
reagents.
The
Baseline
Control
Zone
monitors
the
presence
of

in
the

that
may
alter
the
