EZTest Biological Indicator for Non-Liquid Loads
EZTest® is a self-contained Biological Indicator (BI) for monitoring steam sterilization of Non-Liquid loads, such as instruments and glassware. You can choose between two spore populations (Log 5 or Log 6) based on your local regulatory requirements.
EZTest contains bacterial spores on a filter-paper carrier packaged within a small, thermoplastic culture tube. Inside the thermoplastic culture tube is a sealed-glass ampoule containing G. stearothermophilus spores and a specially-formulated culture medium that turns a dramatic yellow if spores grow. EZTest is easy-to-use and produces visual results within 24 hours.

INSTRUCTIONS
(Included in package)
A. Exposure:
1. Remove an appropriate number of EZTest units from the box
2. Identify the indicators by labeling pertinent process information.
3. It is recommended that at least two BI's be used per cycle.
4. Place the EZTest biological indicators in a horizontal position with Representative materials to be sterilized. These materials should be located in the "worst case" (least lethal location) in the load.
5. Select the appropriate cycle and process the load.
NOTE: If a Flash cycle is selected the goods should be unwrapped. If the come up time is less than one minute, a three minute exposure cycle may have to be extended to four minutes to ensure that the BI is killed.
6. Remove from the sterilizer and allow to cool for at least 10 minutes.
7. Retrieve the EZTest biological indicators from the test load.
8. The chemical indicator on the label changes from blue to black when exposed to steam. This distinguishes exposed from unexposed units. NOTE: a black color does not indicate acceptable sterilization.
B. Incubation:
To activate the media, place the indicator in an upright position in a plastic crusher. Gently squeeze the crusher to break the glass ampoule inside the indicator. Place the activated indicator in the optional Model 1410 Ampoule Incubator or any general purpose microbiological incubator that is adjusted for 55 - 60°C will satisfy the incubation requirements.
C. Interpretation
1. Examine the indicator at regular intervals for any color change (i.e. 8, 12,18 and 24 hrs). The appearance of a YELLOW color indicates bacterial growth. No color change indicates adequate sterilization.
2. Act on a positive test (a color change of yellow) as soon as the color change is noted. Notify appropriate hospital personnel (i.e. Infection Control). Always retest the sterilizer with several EZTest biological indicators throughout the test load. EZTest biological indicators can be subcultured if identification of positive growth is desired. Recommended subculturing procedure techniques are available upon request.
3. The incubation time is 24 hours (meets the US FDA/RIT protocol).
4. Record results
5. Dispose of all used EZTest biological indicators in accordance with your institution's policy. Incinerate or autoclave any positive cultures at 250°F (121°C) for not less than 30 minutes.
Use of Controls:
A. As a positive growth control, place an activated, un-sterilized EZTest indicator in each incubator on a daily basis.
B. Examine the positive indicator at regular intervals (i.e. 4, 8, 12, 18 and 24 hrs). The YELLOW color is evidence of bacterial growth. Record the results. Remove all positive indicators as the yellow color is noticed and dispose of as mentioned above.
C. If the positive control does not grow, do not use the units from this box. Contact us.
Storage:
A. Store EZTest biological indicators at room temperature. Do not desiccate.
B. Do not store these indicators near sterilants or other chemicals.
C. EZTest biological indicators have a shelf life which is clearly designated on each box. Rotate your stock accordingly.
NOTE: Do not use after expiration date printed on package. Dispose of expired indicators by autoclaving at 121°C for not less than 30 minutes.
