Roche, a global pioneer in pharmaceuticals and diagnostics company, announced that the US Food and Drug Administration (FDA) has provided 510(k) clearance for cobas CT/NG for use on the cobas 6800/8800 Systems for the direct detection of Chlamydia trachomatis (CT) and/or Neisseria gonorrhoeae (NG) DNA in both symptomatic and asymptomatic individuals.
“cobas CT/NG on the cobas 6800/8800 Systems provides clinicians with results in which they can have high confidence given the excellent sensitivity and specificity of the assay for all relevant sample types,” said Barbara Van der Pol, international expert on STIs and Associate Professor of Medicine, School of Medicine, University of Alabama at Birmingham. “For the laboratory, the platform provides a tech friendly solution that minimizes hands-on time while maximizing the flexibility of incorporating sexually transmitted infection screening with other assays that are currently available on the system.”
cobas CT/NG is the first assay available in the US for the testing of sexually transmitted infections on the cobas 6800/8800 Systems. It is cleared for use with male and female urine specimens, clinician-instructed self-collected vaginal swab specimens (collected in a clinical setting), clinician-collected vaginal swab specimens, endocervical swab specimens (all collected in cobas PCR media) and cervical specimens collected in PreservCyt Solution.
“Sexually transmitted infection rates are rising worldwide and the cobas CT/NG helps labs meet increasing testing volumes with highest throughput solution on the market today,” said Uwe Oberlaender, Head of Roche Molecular Diagnostics. “With exceptional performance, exemplary workflow and a flexible testing solution, the CT/NG helps labs free up staff to perform other tasks while still ensuring clinicians receive accurate and rapid results to aid in patient management.”
Other STI assays are in development and will further allow laboratories to consolidate high volume STI testing on a single platform. In addition to cobas CT/NG, cobas 6800/8800 Systems menu in the US includes viral load monitoring tests for HIV, HBV, HCV and CMV, as well as MPX, WNV, DPX and Zika for use in screening blood donations. Since its introduction in 2015, the fully automated cobas 6800/8800 Systems have offered labs the fastest time to results with the highest throughput and the longest walk-away time available among automated molecular platforms.
Chlamydia trachomatis is the most common bacterial Sexually Transmitted Disease (STD), with the highest prevalence among youth. Routine screening for chlamydial infection in young women has been demonstrated to reduce infection rates and the long-term consequences of untreated disease, as well as lowering the financial burden on the healthcare system. The Centers for Disease Control and Prevention (CDC) recommends annual Chlamydia trachomatis screening for all sexually active females under 25 years old and additional testing for pregnant women and those with risk factors.1
Neisseria gonorrhoeae is the second most commonly reported bacterial STD in the United States. Infections in males are generally symptomatic, motivating infected patients to seek evaluation by a clinician for identification and treatment before the onset of serious complications. Gonococcal infections in women are often asymptomatic and may not be immediately recognized, which can progress to pelvic inflammatory disease, tubal scarring, infertility and ectopic pregnancy. Screening of sexually active women under the age of 25 and those at high risk for infection is the focus of successful detection programs in the United States.
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, providing users with greater flexibility to consolidate their 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.
