CHOOSING THE RIGHT TEST FOR DETECTING SURFACE CONTAMINATION
In hygiene monitoring, time-to-result is of essence because in case of a failed test, it allows for another cleaning and sanitation to take place before normal activities resume
" The COVID-19 pandemic has created a public health crisis. Because SARS-CoV-2 can spreadfrom individuals with pre-symptomatic, symptomatic, and asymptomatic infections, there-opening of societies and the control of virus spread will be facilitated by robust surveillance,for which virus testing will often be central. After infection, individuals undergo a period of incubationduring which viral titers are usually too low to detect, followed by an exponential growthof virus, leading to a peak viral load and infectiousness, and ending with declining viral levelsand clearance. Given the pattern of viral load kinetics, we model surveillance effectivenessconsidering test sensitivities, frequency, and sample-to-answer reporting time. These resultsdemonstrate that effective surveillance, including time to first detection and outbreak control, dependslargely on frequency of testing and the speed of reporting, and is only marginally improvedby high test sensitivity. We therefore conclude that surveillance should prioritize accessibility, frequency, and sample-to-answer time; analytical limits of detection should be secondary." *
The effectiveness of sanitization procedures is routinely monitored by assessing the quantity of microorganisms present, either using culture methods, which are quantitative and very informative but slow, or by measuring ATP, which is qualitative and less informative but rapid.
The main advantages of Immuno-Detection over PCR are true portability and simplicity: no equipment, electricity, or expertise is required.
Although both PCR and Immuno-Detection are rapid techniques that can be performed within minutes, PCR requires sophisticated equipment and expertise, and is often only available in a laboratory setting. Immuno-Detection tests in a laminar flow format, such as pregnancy test strips, can be carried out by virtually anyone, anywhere, under any conditions, and constitute a reliable indicator of the status of the person or location tested.

COV-Hygien Xpress CHARACTERISTICS
This kit is designed to detect traces of SARS-CoV-2 on surfaces.
It is based on the detection of specific antigens.
All necessary reagents are provided.
NOT for diagnostic use. For surface testing only.
PERFORMANCE CHARACTERISTICS of the Immuno-Detection Strip
Viral detection limit: 5x10E3 pfu/mL
During the development phase, the analytical performance of the assay was performed using a 2-fold serial dilution of the virus (in viral culture medium) in parallel with titrating the same virus preparation on Vero E6 cells (by plaque assay).
Results may vary with cell line, cell line preparation, culture media composition and in particular the presence of serum, as well as lysis conditions
Recombinant nucleocapsid (recN) protein detection limit: 0.3 ng/mL*
During the development phase, the analytical performance was performed on 2-fold serial dilutions of recNP-2.
The limit of detection (LOD) was defined as the last dilution that tested positive (15 tests, 2 independent readers).
Results may vary with recombinant protein, expression system, sequence, purification and storage
No cross-reaction with the following viruses:
- Influenza A
- Influenza B
- Respiratory Syncytial Virus (RSV)
- Respiratory Adenovirus
- Coronavirus HKU1
- Coronavirus OC43
- Coronavirus 229E
- Coronavirus NL63
Kit components manufactured in Europe and the USA

WHAT DOES A POSITIVE OR NEGATIVE RESULT MEAN?
A positive test result indicates that the SARS-CoV protein N is present in the sample at a concentration greater than the detection limit.
A positive result does not indicate whether the virus is inactivated or infectious.
In the case of a hygiene test, a positive result indicates that the cleaning and disinfection procedure has failed to fulfill its purpose.
In the case of investigating surfaces suspected of contamination, a positive result confirms the recent presence of the virus.
In both cases, a positive result suggests that the sampled surface should be cleaned, sanitized, and retested.
SURFACE TESTING REASSURES YOURSELF AND OTHERS
Proper cleaning and sanitization are key to eliminating the threat of invisible COVID-19 contamination, particularly in highly frequented locations with "high-touch" surfaces. If you want to reassure members of the public who use your facility, your collaborators, and other stakeholders that your facility is safe, strengthen the impact of your sanitization procedures by demonstrating that they are effective.
The COV-Hygien Xpress test is a DIY kit that can be used by almost anyone, anytime, anywhere.
With results obtained in minutes, surface contamination can be addressed quickly, so everyone can relax.
