Pictor's Test Poised to Transform Hepatitis B Immunity Testing Amid CDC Guidance Shifts

CARLSBAD, Calif., Dec. 19, 2025 /PRNewswire/ -- With the CDC's Advisory Committee on Immunization Practices (ACIP) recommending post-vaccination antibody testing for hepatitis B, laboratories are facing new demands to assess immunity more effectively. Pictor, a leader in targeted proteomics, today highlighted its ViraScreen-Core™ multiplex antibody assay, an established test already in use by CLIA-certified laboratories, as a ready solution to support this evolving public health guidance. Built for both serum and saliva, the assay offers unmatched flexibility for labs adapting to these changes while addressing broader infectious disease screening needs.

Hepatitis B remains a major global health challenge, yet immunity testing has historically been constrained by cost, operational complexity, and single-analyte approaches. Pictor's ViraScreen-Core™ assay enables simultaneous detection of antibodies to hepatitis B, HIV-1, HIV-2, and hepatitis C from a single sample, reducing turnaround time, conserving patient samples, and supporting evidence-based clinical decision-making.

"Antibody testing gives laboratories flexibility as public health guidance evolves," said Dr Jamie Platt, CEO of Pictor. "By offering a multiplex assay that works with both serum and saliva, we aim to help labs move toward evidence-based immunity assessment without adding operational complexity."

Pictor has completed paired serum and saliva studies demonstrating high concordance, supporting saliva as a reliable testing matrix. This capability may help reduce barriers to testing, particularly in pediatric, community health, and decentralized care settings where blood draws can be challenging.

"Pictor's ViraScreen-Core™ assay represents a valuable addition to our clinical laboratory," said Dr Andrew Brown, Chief Commercial Officer at Sirona Dx. "Compatibility with saliva samples expands the environments in which testing can be conducted while the multiplex format supports streamlined, efficient workflows for infectious disease screening."

Pictor is actively raising capital to support continued commercialization, assay menu expansion, and U.S. deployment of its targeted proteomics platform, building on early laboratory adoption of its technology.
