ATS 2015

  Artificial Test Soil  (ΰ )

    Cleaning Efficacy Indicators for Validation and  routine  monitoring. 

    Individually and as part of complete kits provide  and objective test of cleaning methods that

         are clearly visible and easy to interpret.

    Standardized and verified methods.

    Artificial Test Soil is a test soil comprised of proteins, carbohydrates and hemoglobin.

    It simulates the worst case soiling of medical devices that have been used on patients.

    ATS is used for both testing and validating cleaning procedures of medical devices

         and cleaning equipment.

 REAL             Healthmarks Artificial Test Soil is comprised of the organic contaminants remaining on surgical instruments after clinical use,

                        including protein (~23mg/ml), hemoglobin (~8mg/ml) and carbohydrates (~6mg/ml).

                        These quantities are reflective of the worst case levels found to remain on instruments after patient use, but before reprocessing.

                        The FDA and other international regulatory agencies specify that simulated-use testing should approximate as closely as

                        possible the actual soiling the instrument is exposed to during clinical use.  

                        ATS meets this requirement with extensive research (available upon request) to support it.

 SIMPLE        Our standardized soil is ready-to-mix. You simply add sterile water.

                        Medical device manufacturers must employ an organic challenge.

                        ATS is easy to use to determine and document the effectiveness of your cleaning protocol to remove organic materials from

                        instruments or equipment.

 VERSATILE    Healthmark ATS can be applied to several applications, such as:

                         - Testing the cleaning instructions of medical devices

                         - Ensuring reprocessing adequacy and assurance

                         - Testing microbial load (bioburden) reduction

                         - Training personnel

                         ATS can be inoculated with endotoxin, microorganisms, or other biologics to represent the residuals present on devices after

                         patient use.

 STABLE         Unlike the current organic challenge manufacturers use, ATS offers less variability between batches.

                         ATS is described in various AAMI and ISO standards and FDA Guidance Documents and is well documented in peer-reviewed


                         Our ATS provides long shelf life and is easily stored at room temperature until rehydrated for use.

 COMPLETE   To provide a complete testing solution, ATS can be used with other Healthmark Proformance products to validate the

                         removal of organic soils based on the manufacturers cleaning protocol.

                         Further, ProformanceTM products provide a solution for manufacturers to provide their users with a recommended method

                         to verify the cleaning process, as indicated by AAMI standards:

     Cleaning Validation

 - Apply to medical device (If bioburden is to be included, suspend the test organism is ATS2015 to desired concentration).

 - Allow to dry at room temperature for 30-60 minutes.

 - Post-cleaning, collect a suitable sample from the medical device.

 - Use sterile RO or DI water for sample collection.

 - Assess residual soil parameters (e.g. Protein, hemoglobin, LPS, carbohydrates) or perform viable cell count using accepted protocols.



 - Resuspend test organism in ATS2015 to desired concentration.

 - Apply to medical device or test carrier. Allow to dry at room temperature for 30-60 minutes.

 - Perform cleaning and/or disinfection/sterilization. (Suitable time exposure)

 - Post-cleaning, collect a suitable sample from the medical device.

 - Use sterile reverse osmosis water for sample collection.

 - Assess residual soil parameters (e.g. protein, hemoglobin, LPS, carbohydrate) or perform viable cell count using accepted protocols.




    Healthmark offers BactiQuikTM, a new prepackaged 1 ML vial of microbial suspensions that can be quickly and easily mixed with ATS

    to perform validation testing for disinfection and sterilization.

    The vials contain a pure population of approximately 1x108 CFU/ML of viable Geobacillus stearothermophilus or Bacillus atrophaeus.

    G. stearothermophilus has a known resistance for steam sterilization, and B. atrophaeus for ethylene oxide and dry heat sterilizations.

    Quick, easy and affordable Blood Test Soil (BTS) is a simple, simulated blood soil that visually mimics blood on the exterior of patient-used


    The soil is composed of blood proteins: hemoglobin and albumin, and can easily be used to coat surrogate instruments for cleaning

    verification with Healthmarks Proformance line of products. It has a long, stable shelf life in its lyophilized form. Just rehydrate with sterile

    water and it is ready to use.
