What this trial studies

This clinical trial aims to collect and test clinical samples to evaluate the performance of Access HBV serological marker assays using the DxI 9000 Access Immunoassay Analyzer. It involves both prospective and retrospective sample collection from various groups, including blood donors and hospitalized patients. The study will assess the sensitivity and specificity of the assays, as well as the false initial reactive rate for the HBsAg assay. All samples will be anonymized or pseudo-anonymized, with patient consent required for pseudo-anonymized samples.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older who belong to specific enrollment groups related to hepatitis B status.

Not a fit: Patients without any history or indication of hepatitis B virus infection may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the accuracy of hepatitis B virus diagnostics, leading to better patient management.

How similar studies have performed: Other studies have shown success with similar serological assays, indicating a promising approach for hepatitis B diagnostics.
