Operating Instructions
Readout Procedure
Place unit on a firm level surface. Plug unit into an
appropriate AC grounded outlet.
Follow this procedure for every RRBI to be read:
Allow a 30 minute warm-up period before placing
RRBIs into the incubation wells. The C1 caution
code will disappear when proper incubation
temperature is reached.
It is recommended that the unit be left on to
eliminate warm-up periods. The unit may be
turned off when it is anticipated that it will not be
used for an extended period.
Step 1. While wearing gloves and
safety glasses, CLOSE RRBI cap
by pressing down.
Step 2. CRUSH the glass ampule
(containing growth media) in the
designated crushing well built
into the incubator.
Step 3. Hold the RRBI by the cap
and TAP bottom of the vial on a
tabletop until media wets spore
strip at bottom of vial. Do not tap
vial on unit.
Step 4. Open the cover and
PLACE the RRBI into an
incubation/reader well.

Step 5. CLOSE the cover on the
Attest 290 Auto-reader and wait
for either the red or green
indicator light to signal the result.

Do not remove or change
placement of RRBI once it
is placed into a well. Doing
so may result in loss of
results and the RRBI test
may be invalid.
Attest 290 Auto-reader
Wells are color coded to match the cap of
each type of biological indicator; i.e. the 1291
RRBI with a blue cap goes into a blue well and the
1292 RRBI with a brown cap goes into a brown
A yellow light will come on to indicate the RRBI is
incubating in the reader well and should not be
touched. A yellow light indicates the results are not
available and incubation is in progress.
Do not remove RRBIs until the red (+) or green
(-) light indicates the test is complete.
Note: If RRBIs are inadvertently removed before
the incubation period is complete, an alarm will
sound and all three lights (+, •, and -), for that
incubation well will light. C2 Caution code will also
be displayed. You must return the RRBI to the
reader well within 10 seconds or the results will
be lost.
Do not remove or change placement
of RRBI once it is placed into a well.
Doing so may result in loss of results
and the RRBI test may be invalid.

All red, yellow and green lights will flash for one
second when the cover is opened demonstrating
they are functional.
The cover should only be opened when placing
additional RRBIs into incubation wells or when
removing RRBIs at the completion of the
designated incubation period.
A positive result (+) will automatically be shown as
soon as it is detected. The full incubation period is
required before a negative result (-) is shown. The
Attest 1291 RRBI requires 1 hour of incubation and
the Attest 1292 RRBI requires 3 hours of incubation
before a negative (-) result will be shown. The
negative result will be shown automatically after
completion of the required incubation time.
The processed indicator and the positive control
may also be further incubated for a visual pH color
change. The final negative reading (media remains
purple) for a visual color change is made at 24 hours
(1291) or 48 hours (1292). The positive control
should show a yellow color change of the growth
media. For any incubation beyond 24 hours (1291)
or 48 hours (1292), RRBIs should be moved to a
humidified environment.
Each facility must establish final readout time in its
policy and procedures. The policy should be based
on manufacturer’s instructions for use, scientific
knowledge, current recommendation practices,
applicable compliance requirements, inventory
levels, and the risk to the patient if the medical
device is not sterile.
Attest 290 Auto-reader
Positive Control
Crush, tap and incubate at least one non-processed
Attest 1291 or 1292 RRBI to use as the positive
control each day that a processed RRBI is incubated
and read by the unit. Write a “C” (for “control”) and
the date on the label. The positive control can be
placed in any incubator well of the unit. The
positive control should be the same part number,
from the same manufacturing date and lot number
as the processed RRBI in the unit.
It is good practice to use a positive control each day
a sterilized RRBI is processed. This helps ensure:
- correct incubation temperatures are met.
- viability of spores has not been altered due to
improper storage temperature, humidity, or
proximity to chemicals
- capability of media to promote rapid growth,
- proper functioning of Attest 290 Auto-reader
Interpretation of Results
Each incubation/reader well has three corresponding
indicator lights: a red (+), yellow (•) and green (-)
light. After placing a RRBI into a corresponding
color-coded well, a yellow light will illuminate to
indicate that incubation/reading is in progress.
The final negative processed RRBI reading for a
fluorescence change (green light -) after 1 hour
(1291) or 3 hours (1292) indicates an acceptable
sterilization process. The positive control should
read positive (red light +).
A red light (+), will illuminate and an alarm will
sound (if the sound feature is turned on), as soon as
a positive RRBI result is detected.
If the processed RRBI is further incubated for a
visual pH color change, when special studies are
desired, the media color change from purple to
yellow will also indicate a sterilization failure. The
positive control should show a yellow color change
at 24 hours (1291) or 48 hours (1292). A final
negative color change result (no color change),
media remains purple , is made at 24 hours (1291)
or 48 hours (1292).
At the end of the specified incubation time, if a
negative RRBI result is detected, the green light (-)
will illuminate indicating an acceptable sterilization
After either the green or red light comes on, the
RRBI can be removed from the well. The RRBI
should not be removed or touched when the yellow
light is on.
The positive (unprocessed) control RRBI must
provide a positive fluorescent result (red light +).
Processed RRBI results are not valid until the
positive control reads fluorescent positive (red light
+). With the processed RRBI, a positive (red light
+) result means a sterilization process failure may
have occurred.
Act on any positive result immediately. The positive
result indicates a sterilization process failure may
have occurred. Determine the cause of the positive
RRBI following current facility policies and
procedures. Always retest the sterilizer and do not
use the sterilizer for processing loads until 3
consecutive RRBI results are negative.
Dispose of the used Attest RRBI according to your
healthcare facility policy.

You may wish to sterilize any positive RRBI prior
to disposal.

Attest 290 Auto-reader
Audible Alarm
An audible alarm will sound and the positive
red (+) light will illuminate for the designated
incubation/reader well when a positive result is
detected. This provides results in the least amount
of time without the need to manually take frequent
readings. An alarm will also sound if a RRBI is
removed from the Attest 290 Auto-reader well
before a final result has been detected. Data will be
lost if the RRBI is not replaced in the
reader/incubation well within 10 seconds.
Alarm On/Off
The audible alarm for positive results can be turned
off or on for a particular RRBI. This is
accomplished by pressing the "alarm off" button
after the alarm has sounded. This will turn off the
alarm for that RRBI only. Any positive RRBI
results detected in other wells will result in the
alarm sounding. Removing the RRBI will reactivate
the alarm for that well. Pressing the “alarm off”
button will not silence the alarm for error or caution
code alarm warnings.
To turn the alarm function back on, press the "alarm
off" and "time remaining" buttons at the same time.
The yellow period on the display panel will turn off,
indicating that the alarm is again active.
Time Remaining
When the “time remaining” button is pressed, the
incubation time remaining for each individual
incubation/reader well that contains a RRBI will be
displayed. All three lights for each individual
incubation/reader well will illuminate as the time
remaining is displayed. The process begins with the
incubation/reader well containing a RRBI on the left
and proceeds to the right. The time remaining
appears in hours until there is less than an hour
remaining when it displays minutes remaining.
Temperature Monitoring
The Attest 290 Auto-reader contains an internal
temperature self-diagnostic program. Should the
temperature fall outside the specified range (60ºC
+/-2ºC) an error code will be displayed.
Power Cord Retaining Clip
To turn alarm function off (disable), press both the
"alarm off" and "time remaining" buttons at the
same time. A yellow period will appear on the lower
right corner of the display panel to indicate the
alarm is disabled. The alarm will be disabled for all
positive RRBIs, error codes, and caution code alarm
Place the power cord through the power cordretaining clip on the rear of the Attest 290 Autoreader near the plug in. This will help to ensure that
the power connection does not become
inadvertently disconnected.
Care and Cleaning
Always unplug the Attest 290 Autoreader and allow to cool before
cleaning. Do not immerse the unit in
