INSTRUCTIONS FOR USE – Readout Procedure
Instructions for Biological Indicator (BI) Activation and Incubation
CAUTION: Allow the 3M™ Attest™ Super Rapid Readout Biological Indicator
to cool for the recommended time period before activating. Activating or excessive
handling of the biological indicator before cooling may cause the glass ampoule
to burst.
CAUTION: To avoid the possibility of the 3M™ Attest™ Biological Indicator
vial absorbing fluorescent residue from a chemical indicator or tape, place the
3M™ Attest™ Biological Indicator vial so it does not come in direct contact with
chemical indicators or tape.
CAUTION: Wear safety glasses when activating the 3M™ Attest™ Super Rapid
Readout Biological Indicator.
CAUTION: Wear safety glasses and gloves when activating the 3M™ Attest™
Rapid Readout Biological Indicator 1295.
WARNING: To reduce the risk associated with incorrect results
Do not incubate a 3M™ Attest™ Biological Indicator if, after processing and before BI
activation, it is observed to have a broken media ampoule. Retest the sterilizer with a
new biological indicator.
Activate and incubate 3M™ Attest™ Rapid Readout Biological Indicators 1295 within
1 hour of the completion of the sterilization cycle.
Allow 3M™ Attest™ Super Rapid Readout Biological Indicators 1491 and 1492V to
cool for the recommended time period before activating.
Incubate the 3M™ Attest™ Rapid Readout Biological Indicator 1295 only in 3M™
Attest™ Auto-readers 490 having software versions 4.0.0 or greater.

INSTRUCTIONS FOR USE – Additional Information
BI Placement
All incubation wells in 3M™ Attest™ Auto‑readers 490 having software version 4.0.0
or greater are programmed to provide a final fluorescent result within 24 minutes of
incubation and may be used to incubate both 3M™ Attest™ Super Rapid Readout
Biological Indicators 1491 and 1492V and the 3M™ Attest™ Rapid Readout Biological
Indicator 1295.
Remaining incubation time, in minutes, will be displayed on the LCD display to indicate
the 3M™ Attest™ Biological Indicator is incubating in the reader well and should not be
touched. The time remaining display indicates the results are not available and incubation
is in progress.
While wearing safety glasses (and gloves for the 1295
BI), PLACE BI in Attest™ Biological Indicator Activator.
CLOSE and SQUEEZE Attest™ Biological Indicator
Activator to close BI cap and crush media ampoule.
Immediately remove BI, visually VERIFY the glass
ampoule (containing growth media) has been crushed,
and FLICK BI to ensure purple growth media flows to the
growth chamber at the bottom of the vial.
PLACE the activated BI into any 3M™ Attest™
Auto‑reader 490 well and observe 3M™ Attest™
Auto‑reader 490 LCD panel to confirm correct placement
of the BI. If the BI is correctly seated, the 3M™ Attest™
Auto‑reader 490 LCD panel will display ***, **, * and
then remaining minutes of incubation directly below the
incubating BI.
RECORD BI result.
