FAQ: Are TD-5 and TD-8 Effective Against COVID-19?

FAQ: Are TD-5 and TD-8 Effective Against COVID-19?

At the forefront of every healthcare worker’s mind these days are all the new risks posed by COVID-19. It is easy to feel like COVID-19 is an insurmountable disease which requires a major shift in how we think about high-level disinfection. In light of this new challenge, can facilities continue to rely on the same high-level disinfectants they used before COVID-19, like TD-5® and TD-8®?

For starters, TD-5 is a single-use, 2.65% glutaraldehyde based disinfectant while TD-8 is a single-use, 0.59% Ortho-phthalaldehyde (OPA) based disinfectant. Both these products have been cleared for use as high-level disinfectants by the FDA. In order to have been cleared by the FDA, both TD-5 and TD-8's effectiveness were tested against various kinds of bacteria, fungi, spores, and viruses. When used in CS Medical’s TEEClean® Automated TEE Probe Cleaner Disinfector or TD 100® Automated TEE Probe Disinfector, both TD-5 and TD-8 were proven to kill these microorganisms. So while TD-5 and TD-8 have not been specifically tested against SARS-CoV-2 (the virus that causes COVID-19), they have been tested against other, harder to inactivate viruses and proven effective.

Given the obstacles posed by COVID-19, your facility should certainly continue to implement best practices, like CS Medical’s 10-Step TEE Complete Care Process, in order to supplement the efficacy of TD-5 and TD-8 before and after high-level disinfection. After all, if a perfectly high-level disinfected TEE probe is mishandled after disinfection, it could become contaminated and contribute to the spread of COVID-19 or other HAIs. Ensure that your facility is following the guidelines set out by your infection preventionists at all times during the high-level disinfection process.

Fortunately, while COVID-19 is presenting the world with all sorts of new and difficult hurdles, high-level disinfection is one constant that can remain the same. TD-5 and TD-8 are just as effective against SARS-CoV-2 as they are against any other microorganism. Additionally, since they both come in single-use bottles, they ensure maximum potency and effectiveness whenever high-level disinfecting your facility’s TEE ultrasound probes. This will help your facility maintain its goal of stopping the spread of COVID-19 and contribute to the worldwide effort to stop this pandemic in its tracks.


About CS Medical

CS Medical LLC has pioneered the automated disinfection process for Transesophageal ultrasound probes with the development and release of the TD 100® Automated TEE Probe Disinfector. In 2005, the TD 100 was the first FDA cleared automated disinfection process with printed verification for Transesophageal ultrasound probes. During the disinfection process, the TEE probe receives high-level disinfection in (5) five minutes from TD-5® or TD-8® followed by (5) five complete rinse cycles before disinfection confirmation is acknowledged and a report is printed. The verification report indicates probe contact time with the high-level disinfectant as well as the average temperature of the single-use disinfectant during each cycle.

For more than 15 years and over 4 million high-level disinfections, the TD 100 Automated TEE Probe Disinfector has eliminated manual reprocessing of delicate and expensive TEE ultrasound probes while also providing a repeatable and FDA cleared disinfection process. The TEEClean® Automated TEE Probe Cleaner Disinfector will continue the TD 100's work by automating the required cleaning process for the TEE probe before high-level disinfection. TEEClean, with electronic record data logging, printed verification reporting, FDA cleared cleaning, and high-level disinfection will be the standard of care for TEE ultrasound probes.

CS Medical's TEE Complete Care® products provide quality device care and storage by minimizing healthcare operational costs, improving service readiness and increasing regulatory compliance.
