What this trial studies

This project uses dried blood spot sampling to screen for hepatitis B, hepatitis C, and HIV among people with current or past injection or nasal drug use and people on opioid substitution therapy. Capillary blood is collected onto filter paper and sent for laboratory testing for viral markers, enabling testing outside standard phlebotomy settings. Individuals with known active viral infections are excluded so the focus is on finding undiagnosed infections. The approach aims to improve reach of screening within addiction services and community sites in Normandy.

Who should consider this trial

Good fit: Ideal candidates are current or former intravenous or nasal drug users, including people on opiate substitution therapy, who do not have a known active viral infection.

Not a fit: People who already have a confirmed active hepatitis B, hepatitis C, or HIV infection or those who are not drug users are unlikely to benefit from this screening approach.

Why it matters

Potential benefit: If successful, this could detect infections earlier in people who use drugs and help link them to care using a minimally invasive, easy-to-use test.

How similar studies have performed: Dried blood spot testing for HIV, hepatitis B and C has been validated in multiple studies and is increasingly used to expand screening, so the approach is supported by prior evidence.
