Sexually Transmitted Infections
The economic and emotional burden of STIs underscores the need for effective screening
Sexually transmitted infections (STIs) constitute a major burden on global health, as this group of infections ranks among the top five disease categories for which adults seek healthcare. More than 1 million people acquire an STI every day.1
The astounding incidence of these infections places the healthcare system under severe economic strain. In the US, the lifetime cost of treating eight of the most common STIs contracted in just one year is $15.6 billion. Furthermore, the total direct medical cost in the US associated with chlamydia, gonorrhea, and herpes simplex virus-2 (HSV-2) infections alone is estimated to be a staggering $1.2 billion annually.
However, the substantial monetary costs on healthcare overall cannot be overshadowed by the severe health consequences.

cobas® 4800 CT/NG Test
The Simple Path to Accuracy
CT and NG multiplex assay with flexible order capability
A qualitative multiplex assay that simultaneously detects two CT independent DNA targets – one in the cryptic plasmid and the other on the CT genome. This design can detect infections caused by the wild type CT, the Swedish variant (nvCT), and other Chlamydia strains that may harbor deletions in the cryptic plasmid, or those that do not carry the cryptic plasmid.
DR-9, a direct repeat region and target of the NG assay, makes it highly specific to the NG species. No cross reactivity with commensal Neisseria or other bacterial species has been observed with the NG assay.
Features and Benefits
Easy to learn, easy to use
- Reduces labour costs and training time
- Intuitive software walks the user through the entire set-up process
- Bidirectional LIS connection protects results integrity and reduces repetitive tasks
- Automated result algorithm provides clear positive, negative or invalid results
Quality control at every step
- An internal control utilizing an identical randomized internal target sequence is added to each sample and is used throughout the entire process, from sample preparation to amplification and detection
- The internal control minimizes the risk of false negative results due to inhibition
- The AmpErase enzyme degrades previously amplified targets, allowing sample prep and detection in the same lab
