Respiratory Health

It doesn’t take a global COVID-19 pandemic to emphasize the importance of fast, reliable diagnostic testing for respiratory infections… although the appearance of one certainly has raised the stakes.

At SEKISUI Diagnostics, we’ve dedicated decades to innovating and improving diagnostic testing for various respiratory illnesses because it isn’t a matter of if another pandemic will appear, when—and only through better therapies, tests, and diagnostics- we will be truly prepared for what’s ahead.

COVID-19 Testing

An easily transmissible virus with new variants continuously emerging

SARS-CoV-2 is highly contagious and that is passed between people through respiratory droplets. Additionally, new variants of SARS-CoV-2 continue to emerge and circulate around the world. These characteristics create waves of high COVID-19 infection rates.

Stopping the next wave with frequent testing

Rapid COVID-19 antigen testing can be used to identify infection early and to minimize incidence rates in communities and particularly among frequently exposed workers and immunocompromised individuals. Rapid point of care tests are essential to mitigate the spread of COVID-19 and resurgence of the pandemic.

OSOM® COVID-19 Antigen Rapid Test

The OSOM® COVID-19 Antigen Rapid Test is a lateral flow chromatographic immunoassay intended for the qualitative detection of the SARS-CoV-2 nucleocapsid protein antigen in direct mid-turbinate (MT) nasal swab specimens collected by a healthcare provider from individuals suspected of COVID-19 within the first 7 days of symptom onset.

Influenza Testing

Detecting Influenza is a Rapidly Evolving Challenge 

Influenza is widely known as the source of the first major pandemic of the modern era—but a lot has changed since the Influenza pandemic of the early 20th century, including the virus itself. Today, detecting Influenza with confidence requires testing that can evolve right alongside the virus. 

Stopping the Spread with Reliable, Robust Testing 

At SEKISUI Diagnostics, we’ve spent decades innovating and improving the world’s Influenza testing capabilities. With advanced point-of-care testing specifically designed for Influenza, we help healthcare providers and patients see the virus with clarity and take real steps to stop it.

Strep A Testing

An Uncomfortable Infection with Serious Symptoms 

Most people are familiar with Group A Streptococcus as an infection distinguished by painful coughs and a sore throat. But while the traditional visible inspection can sometimes aid in diagnosis, diagnostic testing is the key to confidently detecting strep before it develops into something worse. 

Stopping Strep (And Scarlet Fever) With Testing 

Left untreated,  Group A Streptococcus can sometimes develop into scarlet fever—but with early detection, we can help stop both the progression of the disease and the spread to other individuals. Our diagnostic tests are specifically designed to detect strep early and quickly, helping doctors protect more patients.

Respiratory Syncytial Virus (RSV) Testing

A Widely Unknown Virus That is All Too Common 

Chances are that most patients have never heard of respiratory syncytial virus (RSV), mainly because most people infected recover with minimal medical intervention. However, for infants and older adults, the symptoms of RSV can be quite serious—and, often, difficult to distinguish from the flu. 

Protecting the Most Vulnerable with Reliable Testing 

Proper and early diagnosis of RSV is key to minimizing the impact of symptoms and, most importantly, stopping the spread to those most likely to be impacted. With reliable, rapid point-of-care testing, we can better identify and treat RSV to protect those most at risk.
