Indoor Environmental Hygiene (IEH) Assessment

Creating Safer, Healthier Indoor Spaces with Science-Backed Hygiene Solutions

Why Indoor Environmental Hygiene Matters

Most people spend more than 90% of their time indoors, making indoor hygiene essential to health and well-being. Poor indoor hygiene can contribute to the spread of infectious diseases, absenteeism, and even reputational damage for business.

At Avalon Steritech, we specialize in scientific, data-driven IEH assessments to help organizations identify hidden health risks and create safe environments for employees, customers, and the community.

Don't wait until problems escalate – take proactive steps today to ensure a safer, healthier future for your facility and those who depend on it.

The Hidden Dangers of Pathogens in Indoor Spaces

Unlike pollutants like dust or CO₂, pathogens are living organisms that spread and multiply, posing a direct risk to human health.

Why Pathogen Detection Matters More Than Ever:

✅ Prevents Disease Outbreaks:

  • Bacteria, viruses, and fungi can linger on surfaces and in the air, leading to infections

  • Early detection allows for targeted disinfection before an outbreak occurs.

✅ Addresses Health Risks Conventional Assessments Miss:

  • Visual cleanliness does not always mean pathogen-free; ATP testing and multiplex diagnostics reveal microbial contamination.

✅ Reduces Absenteeism & Healthcare Costs:

  • Workplace and school infections lead to increased sick leave and lost productivity.

  • Proactive hygiene measures help organizations cut down on healthcare expenses and disruptions.

✅ Protects High-Risk Populations:

  • Hospitals, elderly homes, and childcare centers house individuals who are more vulnerable to infections. Regular assessments reduce cross-contamination risks in these settings.

When people think about indoor environmental assessments, they often focus on air quality, lighting, humidity, and ventilation. While these factors are important, they do not address one of the most critical threats to health — pathogens.

At Avalon Steritech, we go beyond conventional assessments by specializing in pathogen detection, identifying invisible biological threats that can cause illness and outbreaks.

ATP Testing for Cleanliness Validation

  • ATP (Adenosine Triphosphate) is a complex organic compound found in all living cells, including bacteria, fungi, and other microorganisms. It serves as the primary energy currency for cellular processes, driving the metabolism and growth of these organisms.

    The presence of ATP on surfaces can indicate the existence of biological contamination, making it an essential marker for assessing the hygiene status of a facility. The ubiquitous nature of ATP across various organisms makes it a versatile indicator of cleanliness, detecting the presence of microbes in diverse environments.

  • The principles behind ATP testing lie in the bioluminescence assay. When ATP comes into contact with the reagent in the testing device, it triggers a reaction that produces light. The intensity of the light generated is directly proportional to the amount of ATP present in the sample and measured in Relative Light Units (RLU).

    The RLU value obtained provides instant and quantitative feedback on the cleanliness of the surface. Higher RLU values indicate a higher level of biological contamination and probably insufficient cleaning. Lower RLU values suggest a cleaner surface with minimal microbial activity, validating the effectiveness of existing hygiene practices.

  • ATP testing involves collecting samples from surfaces with a specialized swab, inserting the swab into the reagent in the luminometer, measuring the ATP levels, and interpreting the results to determine the level of biological contamination.

    Our trained technicians follow standardized sampling protocols and interpret the results based on industry best practices and client-specific requirements.

  • Interpreting ATP test results requires establishing a baseline or benchmark for acceptable cleanliness levels. These benchmarks may vary depending on the industry, regulatory requirements, and specific facility needs. By comparing the RLU values obtained from regular ATP testing to the established benchmarks, facilities can quickly identify areas that require additional cleaning or disinfection.

  • The actions taken based on ATP test results depend on the RLU values obtained and the established cleanliness benchmarks for your facility. If the ATP levels exceed the acceptable threshold, immediate cleaning and disinfection of the affected surfaces should be carried out. Retesting after cleaning is essential to verify the effectiveness of the remedial actions. Consistently high ATP levels may indicate the need for a review and optimization of your cleaning protocols or staff training.

Emerging Virus Diagnostics Device

Multiplex Pathogen Detection System

  • Current test panel offerings include:

    1. Respiratory Viral Panel: Covering a broad spectrum of respiratory viruses, including influenza, RSV, and SARS-CoV-2, this panel aids in the rapid identification of respiratory infections.

    2. Gastrointestinal Viral Panel: Designed to detect common viral causes of gastroenteritis, such as rotavirus, norovirus, and adenovirus, this panel assists in the diagnosis and management of gastrointestinal illnesses.

    3. Central Nervous System Viral Panel: Targeting viruses associated with neurological infections, such as herpes simplex virus, enterovirus, and West Nile virus, this panel supports the diagnosis of viral meningitis and encephalitis.

  • To cater to a wide range of clinical and research needs, the testing panels are designed to cover the most relevant and prevalent viral pathogens, ensuring that you have the tools you need for accurate and timely diagnosis.

  • Already being used in a number of private clinics and hospitals for screening and diagnosis. The device can be used for medical and non-medical fields for pathogen detection

  • Sensitivity is vital in early detection of a potentially infected individual during the onset of infection when the viral load is usually low. Specificity is critical in determining whether particular pathogen targets are present in the sample. Our technology achieves 100% PPV and 97.5% NPV

Industries We Serve

Our solutions are tailor for various sectors to ensure optimal indoor hygiene.

🏥 Healthcare & Elderly Homes – Protecting vulnerable patients from MRSA, RSV, norovirus, and other infections
🏢 Corporate & Offices – Minimizing workplace illness and absenteeism
🏫 Schools & Universities – Reducing the spread of flu, COVID-19, and other contagious diseases
