    • MRSA (Methicillin Resistant Staphylococcus Aureus)
    • MDR (Multiple drug resistant)
    • Other
  • Moulds
  • Yeasts
  • Other contamination

 

How large is the sampling area / room in cubic metres?

 

 

Do you want to test for all sources of infection / contamination or just those caused by non-human sources (e.g. Vents, etc.)?

Air Guardian Protocol Procedure 

  1. Select type of Agar plate for the sample.
  2. Select areas of concern in your workplace/hospital (see checklist).
  3. Select sample height for each area: 0, 1 or 2 m (see checklist).
  4. Put on surgical gloves.
  5. Label the Agar plates: Sample 1, 2, 3, etc…
  6. Place a plate into each Air Guardian so the plate faces the opening, remove the Agar plate lid and close the Air Guardian making sure you don’t touch the Agar.
  7. Place each Air Guardian at each sample area at the required height (see checklist).
  8. If you want to test for all sources of infection / contamination, set the Air Guardians to have no delay time and then activate the Air Guardians.
  9. If you want to test for sources of infection / contamination caused by non-human sources (e.g. Vents, etc.), set the Air Guardians to have a 15 min delay and then activate the Air Guardians.  Then isolate the room until the sampling has completed.
  10. After the sample time has finished, put on surgical gloves.
  11. Open the Air Guardians and replace the Agar plate lids onto the Agar plates.
  12. Take out the Plates and tape the Agar plate lids to the Agar plate bases with surgical tape.
Package the plates and sent them to the following address for incubation and analysis:  MEDIPURE Ltd. Unit 8, Waverton Business Park, Waverton, Chester, Cheshire, CH3 7PD.
