Abbott Obtains FDA Clearance for First Test that Simultaneously Detects Four Common Sexually Transmitted Infections (STIs) as Cases are on the Rise
  • Abbott's multiplex test runs on its most advanced molecular PCR platform, the Alinity™ m system, which provides fast results in high volumes – detecting four infections simultaneously
  • Test provides a critically important tool as people return to regular STI testing; a pause in testing during the pandemic contributed to an increase of STI cases 1,2
  • Pandemic has shown value of at-home testing and sample collection, and Abbott plans to bring that convenience and discretion to additional areas in the future, including for STIs

ABBOTT PARK, Ill., May 4, 2022 /PRNewswire/ -- Abbott (NYSE: ABT) announced today it has received FDA clearance for its Alinity™ m STI Assay. The test simultaneously detects and differentiates four common sexually transmitted infections (STIs). STIs, when left untreated, can lead to severe health complications, including increased risk of getting certain cancers and infertility.3

The first-of-its-kind multiplex test will help address increasing STI rates, after disruptions in delivery of care during the pandemic contributed to a decline in routine STI screening and an increase in cases.1

The Alinity m STI test for Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Trichomonas vaginalis (TV), and Mycoplasma genitalium (MG) requires one swab sample or a urine sample collected in a healthcare setting by either a clinician or by the patient. The test runs on Abbott's Alinity m system — the company's most advanced high-volume laboratory molecular instrument. Alinity m uses polymerase chain reaction (PCR) technology, with high sensitivity in detecting infectious diseases. This test can help healthcare providers save time, increase efficiency and better serve patients.

"Over the past several years, STI cases have been on the rise, and we expect to see increasing rates as people resume testing after delaying during the pandemic," said Kathryn Becker, Ph.D., global director of scientific affairs innovation in Abbott's diagnostics business. "With that comes an increased need for effective and efficient testing. This four-plex STI test gives healthcare providers a more holistic picture of someone's health in a single test, helping to support the best treatment plan to address these common STIs individually or as co-infections."

The need for efficient STI testing

According to the Centers for Disease Control and Prevention (CDC), 20% of the U.S. population has an STI4. Every year for the past six years of available data, the CDC reported that cases of chlamydia, gonorrhea, and syphilis reached an all-time high. 1

Advanced molecular testing allows those living with these infectious diseases to be diagnosed correctly and can help healthcare providers determine how individuals are responding to treatment. While the COVID-19 pandemic may have contributed to less sexual activity for some and limited availability of clinical services for STIs, there's a potential risk of even higher increases of STI cases if sexual activity resumes, but regular STI testing and treatment does not.5

The pandemic accelerated the demand for additional channels for healthcare delivery, a trend reflected in Abbott's commitment to improving the quality and accessibility of diagnostic testing. "The pandemic showed us the value of having aspects of testing available to people in their homes," said Becker. "As we look to the future of testing, we will be focused on bringing that kind of convenience and discretion for STIs and other conditions."

About Alinity m

Assays available for use on the Alinity m system in the U.S. include: SARS-CoV-2 (Emergency Use Authorization), Resp-4-Plex (Emergency Use Authorization), HCV (Hepatitis C), HBV (Hepatitis B), HIV-1 (Human Immunodeficiency Virus type 1), and STI (CT/NG/TV/MG). Alinity m systems are designed to be more efficient – running more tests in less time and minimizing human errors – while continuing to provide quality results. The system helps to improve laboratory workflow and efficiency with its large capacity and fast turnaround time, running up to 1,080 tests in a 24-hour period based on laboratory practice and workflow. The availability of the Alinity m system and tests varies by geography. More information is available at
