Labcorp is looking to plug the gap in hepatitis D (HDV) monitoring with a new reflex testing solution to help find more patients with this form of the virus earlier.
Hepatitis D only occurs in people with hepatitis B and is considered the most severe form of viral hepatitis.
The disease can increase the risk of liver cirrhosis, liver cancer and other serious complications. Labcorp says, however, that “many eligible patients are never evaluated for coinfection.”
Testing has often been limited to manual methods or lab-developed tests that can vary in consistency.
Labcorp is looking to change that with its new HDV reflex testing option, which falls within its Comprehensive Hepatitis Testing portfolio.
As part of this new test, clinicians can now select a reflex testing option that automatically performs hepatitis D testing on the original blood sample when hepatitis B is found.
This means extra blood draws or orders for new testing can be eliminated.
Labcorp estimates that between 70,000 and 150,000 people in the U.S. are living with an active HDV infection but found that fewer than 20% of hepatitis B-positive patients are tested for the disease.
“This gap in testing contributes to substantial underdiagnosis and delays in care,” the company said in a statement.
Labcorp said that as part of this launch, it is also offering “enhanced hepatitis B reporting with simplified result interpretations designed to support clinical decision-making.”
It’s been a good year for innovation in the HDV space. Just last month, Roche introduced its new cobas Hepatitis D Virus test. This became the first high-throughput, fully automated HDV assay on the market.
Back in May, Gilead’s Hepcludex also became the first treatment for chronic HDV infection in the United States.
