With a processed 3M™ Attest™ Rapid Readout Biological Indicator, a positive (+) result
indicates a sterilization process failure. Act on any positive test results immediately.
Determine the cause of the positive 3M™ Attest™ Rapid Readout Biological Indicator and
retest the sterilizer following current facility policies and procedures.
Optional Visual pH Color Change Result
3M™ Attest™ Rapid Readout Biological Indicators 1295 for Vaporized Hydrogen Peroxide
Sterilization may be further incubated for a visual pH color change. Due to the high
sensitivity of the fluorescent result, there is no advantage to continuing to incubate 3M™
Attest™ Rapid Readout Biological Indicators 1295 after the fluorescent result has been
determined and documented. This optional further incubation is not intended for routine
use but may be used for special studies.
In the case of a positive control BI, a yellow color change of the growth media will appear
within 24 hours. Any observation of a yellow color within the vial indicates a positive
result. The pH color change result can be recorded and the BI discarded as soon as the
yellow color is observed and the result recorded.
For processed 3M™ Attest™ Rapid Readout Biological Indicators 1295, the use of a
humidified incubator is recommended to avoid media dry out. If a visual pH color change
result is desired, transfer the processed 1295 BI to a humidified incubator after the
fluorescent result has been determined in the 3M™ Attest™ Auto
‑
reader 490H. A media
color change from purple to yellow indicates a sterilization process failure. A negative pH
color change result, i.e., media remains purple, can be assessed at 7 days.

AUTO

READER 490H
Audible Alarm
An audible alarm will sound, the LCD display backlight will flash, and a (+) symbol will
be displayed on the LCD panel directly under the incubating BI when a positive result is
detected. An alarm will also sound if a 3M™ Attest™ Rapid Readout Biological Indicator
is removed from the 3M™ Attest™ Auto
‑
reader 490H well before a final result has been
detected. Data will be lost if the 3M™ Attest™ Rapid Readout Biological Indicator is not
replaced in the incubation well within 10 seconds.
Alarm On/Off
The audible alarm for positive results can be turned off for a particular 3M™ Attest™
Rapid Readout Biological Indicator. This is accomplished by pressing the
“
Buzzer Alarm
OFF
”
button after the alarm has sounded. This will turn off the alarm for that BI only. Any
positive 3M™ Attest™ Rapid Readout Biological Indicator results subsequently detected
in other wells will result in the alarm sounding. Removing the 3M™ Attest™ Rapid
Readout Biological Indicator will reactivate the alarm for that well. Pressing the
“
Buzzer
Alarm OFF
”
button will not silence the alarm for error or caution code alarm warnings. To
disable the alarm, see configuration section.

reader 490H LCD
display will present the unique Media Access Control (MAC) Address for the device.
Temperature Monitoring
The 3M™ Attest™ Auto

2ºC) an error
code will be displayed. The heater block temperature may be checked by depressing the
Temperature button once.
