Solutions to Monitor the presence of SARS-CoV-2* (COVID-19) in your facility
BioScreen/ALS provides routine analysis of critical environmental surfaces
to determine the extent and persistence of COVID-19. The
results will help you monitor and strengthen the effectiveness
of sanitation measures put in place.
Avoid work stoppage over coronavirus fears—partner with ALS to identify SARS-CoV-2 contaminated surfaces in your facility.
Where to swab
Help protect your employees by identifying which surfaces in
your facility may play a role in the onwards transmission of
COVID-19. Identify and list common areas where employees,
vendors or clients gather or touch as they pass through your
place of business.
Common surfaces include ▼
» time clocks
» restrooms
» carts
» doors and handles
Sample Analysis
-
» Molecular test for the qualitative
detection of SARS-CoV-2 in swab
samples of environmental surfaces by
real-time reverse transcription PCR.
» The nucleic acid is extracted, purified,
and reverse transcribed into cDNA
followed by nucleic acid amplification
and detection.
» A positive result indicates the presence
of SARS-CoV-2 genetic material.
🕒 24–72 hour turnaround time
Sampling Kit
Min. submission 10
Each sampling kit contains all of
the necessary items to samples the number of surfaces requested.

BioScreen Preservative Effectiveness Testing
Antimicrobial Preservative Effectiveness Testing Global Pharmacopoeia Standards for Topical Products
The following table is a summary of the different tests and specifications required by specific regions for Antimicrobial (Preservative) Effectiveness Testing (AET). The regions encompass Japan, Europe (including Great Britain), and the United States. In addition to the designated organisms, additional organisms can be used to challenge the product.
Important note: The Validation Test demonstrates the efficiency of the neutralizers used in the plate count method in inactivating the antimicrobial preservatives contained in the test sample. This is required by all compendial methods. Failure to properly neutralize the preservative system during testing can result in false negative results where lack of organism recovery may be due to inhibition of the organism.

[1] The PCPC test allows the microorganisms to be pooled into groups of bacteria, fungi and mold. Additional organisms are listed in the procedure. In addition, at least one rechallenge is recommended for an additional 28 days.
[2] The acceptance criteria listed above is only for topical products. The criteria will differ for other categories.
[3] The EP/BP A criteria express the recommended efficacy to be achieved. In justified cases where the A criteria cannot be attained, for example, for reasons of an increased risk of adverse reactions, the B criteria must be satisfied.
