Roche announced US Food and Drug Administration (FDA) 510(k) clearance for the cobas® TV/MG test for use on the cobas 6800/8800 Systems for the detection of Trichomonas vaginalis (TV) and/or Mycoplasma genitalium (MG) DNA in both symptomatic and asymptomatic patients. Laboratories can now simultaneously process from a single patient sample a combination of Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Trichomonas vaginalis (TV), and Mycoplasma genitalium (MG), which provides clinicians the information they need to screen and diagnose sexually transmitted infections (STIs) and improve patient care.
The addition of the cobas TV/MG test continues the expansion of the testing menu on the cobas 6800/8800 Systems, supporting true consolidation and testing efficiencies. The cobas TV/MG test has been validated for use with broad specimen types, including sample types comparable to those available for use with the cobas CT/NG test: male/female urine; endocervical swabs and vaginal swabs (both clinician collected and patient collected in a clinical setting).
“The launch of cobas TV/MG continues our expansion of our STI menu, giving healthcare providers and their patients greater access to more information from a single sample,” said Mario Torres, Head of Roche Molecular Diagnostics. “By coupling cobas TV/MG with the recently launched cobas CT/NG for the detection of Chlamydiatrachomatis (CT), Neisseria gonorrhoeae (NG), laboratories have a highly flexible, moderate complexity, high throughput automated solution to support their testing needs.”
“The addition of Mycoplasma genitalium (MG) and Trichomonas vaginalis (TV) detection to the cobas 6800/8800 Systems is an important step forward in the ability to diagnose sexually transmitted infections.” said Barbara Van Der Pol, Associate Professor of Medicine, School of Medicine, University of Alabama at Birmingham. “These new analytes, in conjunction with the approved Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) molecular diagnostic assays, will support a more thorough assessment of the potential pathogens responsible for discharge-causing STI. As a result, clinicians can more easily identify co-infections and utilize appropriate treatment strategies earlier in the patient management process.”
The fully automated cobas 6800/8800 Systems offer the fastest time to results with the highest throughput and the longest walk-away time available among automated molecular platforms, providing laboratories with improved operating efficiency and the flexibility to adapt to changing testing demands.
About Trichomonas vaginalis
Trichomonas vaginalis (TV) is the most common non-viral sexually transmitted infection (STI) in the world. About 70% of people infected with TV do not have any symptoms. Those with symptoms may experience itching, burning or irritation of the genital area, discharge of the penis for males and a change to vaginal discharge with an unusual fishy smell for females. Left untreated, TV can increase the risk of spreading or contracting other STIs such as HIV. Pregnant women with TV may experience complications such as preterm delivery and low infant birth weight.
About Mycoplasma genitalium
Mycoplasma genitalium is a fastidious bacterium first isolated in 1980 from the urethral swabs of two symptomatic men with non-gonococcal urethritis (NGU).4 Mycoplasma genitalium infections are often asymptomatic. However, infections caused by this bacterium have been associated with male and female urethritis, balanoposthitis, prostatitis, cervicitis, pelvic inflammatory disease and male and female infertility.5Additional complications, such as preterm delivery and extra-genital infections, have been reported. Prevalence has shown to be as high as ~40% when testing using various molecular assays in select patient populations.6,7
About the cobas 6800/8800 Systems
Since 2014, the cobas 6800 and cobas 8800 Systems have established the new standard for routine molecular testing by delivering fully integrated, automated solutions that serve the areas of viral load monitoring, donor screening, sexual health and microbiology. Based on Nobel prize-winning PCR technology, the systems deliver proven performance with full automation, increased throughput, fast turnaround time and complete track connectivity validated for molecular testing, providing users with greater flexibility to consolidate their IVD and LDT testing to a single system while increasing overall workflow efficiencies.
The systems provide up to 96 results in about 3 hours and a total of 864 results for the cobas 6800 System and 1,824 results for the cobas 8800 System from an eight-hour shift. Both make it possible for labs to perform up to three tests in the same run with no pre-sorting required. The systems also enable up to eight hours (cobas 6800 System) and four hours (cobas 8800 System) of walk-away time with minimal user interaction.
