The science behind IDEXX-QC microbiology tests

Fully traceable back to known cultures.

A proprietary gel-like matrix makes IDEXX-QC tests easy to use and ensures the stability of organisms. This saves time in testing and preserves the shelf life of the tests.

Can be used in a presence/absence (P/A) vessel, Quanti-Tray, Quanti-Tray/2000, or Quanti-Tray/Legiolert (Legiolert only).

How to use


Perform the following steps at room temperature:

Step 1

Remove vial(s) from freezer. Equilibrate at room temperature for 15 minutes.

Step 2

Open a vial and aseptically transfer the coloured disc, located on top of the cotton plug, to an appropriately labeled vessel of 100 mL of sterile, nonbuffered, oxidant-free water in a sterile vessel. 
Note: The disc may occasionally stick to the vial. If this occurs, use sterile tweezers to gently remove the disc.

Step 3

Swirl the sample and allow to stand for 10–15 minutes. The disc should completely dissolve. After it is dissolved, mix by inverting the vessel 10 times.

Step 4:

Use within 30 minutes of hydration.

Step 5:

Review lot activity information on the certificate of analysis to determine if a dilution of hydrated sample is required. Please refer to the IDEXX-QC outer kit label for the correct lot number.
