Type (Chemical Indicators and Biological Indicators)
By type, the biological indicators segment is likely to account for around 68.6% sterility indicators market share by 2037. The market growth is driven by biological indicators’ unmatched accuracy, regulatory backing, and technological innovations. Biological indicators are widely regarded as the gold standard for sterilization validation. They use highly resistant bacterial spores to verify the efficacy of sterilization processes such as steam, ethylene oxide, and radiation sterilization. Their accuracy and reliability in detecting sterilization failures make them essential in the healthcare and pharmaceutical industries.
The increasing focus on infection prevention in hospitals and healthcare facilities has boosted the use of biological indicators as part of quality assurance programs for sterilization processes. The development of rapid-readout biological indicators has significantly reduced the time needed to confirm sterilization efficacy, making them more practical for routine use. This has enhanced their adoption in hospitals and industrial settings.
Moreover, several leading companies are driving the sterility indicators market by providing advanced biological indicators for sterilization. For instance, STERIS Life Sciences provides high-quality biological indicators in various forms to the pharmaceutical, medical device, and biotechnology industries. STERIS biological indicators come in two types of spores: Bacillus atrophaeus for ethylene oxide (EO) and dry heat applications, and Geobacillus stearothermophilus for steam sterilization applications. STERIS also provides custom sterilization indicators customized to specifications.
Technique (Heat sterilization, Low-temperature sterilization, Filtration sterilization, Radiation sterilization, and Liquid sterilization)
By technique, the heat sterilization segment in sterility indicators market is poised to register a profitable revenue share during the forecast period. Steam sterilization, a common form of heat sterilization, is one of the most reliable and cost-effective methods for ensuring sterility in medical instruments and pharmaceutical products. It is widely used in hospitals, surgical centers, and laboratories due to its effectiveness against a broad range of microorganisms, including spores.
Regulatory authorities, such as the FD and ISO, mandate the use of heat sterilization in many sterilization processes, particularly in the pharmaceutical and medical device industries. Innovations in heat sterilization equipment, such as automated autoclaves with integrated monitoring systems, are driving demand for sterility indicators that support these advanced devices.
