Hi, reposting this because I would appreciate some guidance and input.
I'm looking to change the media that we use for gloved fingertip, surface, and air sampling. We do in-house air (passive) sampling, surface sampling, and gloved fingertips on a weekly basis as part of our QC procedure.
In the past, we've used EnviroTest ET1000 media paddles from QI Med for all three. I don't believe that these paddles are appropriate to use for passive air sampling - the manufacturer's guidelines only indicate how to use them for air sampling via impaction. I know that 797 doesn't recommend use of settling plates, but our PIC would like to continue using them as NJ BOP was impressed that we do in-house air sampling, even if it's only passive.
The questions I have are these:
I was looking at plates from Millipore, but would appreciate any other suggestions/vendors.
Thanks in advance for any thoughts you may have,

At our facility, we use Hardy Diagnostics #p34 plates for our EM. This is for active air sampling using an air sampler, surface, and fingertips. We use to use the finger paddles for gloved finger tip but it is more costly than the p34 plates. I don't believe there is a requirement for separate types of media for settling/surface/finger as long as the media is able to grow colonies.
If you are planning on testing for fungus then you do need two different types, TSA and SAD/MEA.
Hope this helps. Thanks
