Testing a finger-prick blood test for three serious viruses

This research study is testing a new, easier way to screen for three serious viruses—hepatitis B, hepatitis C, and HIV—using a small dried blood spot collected from a finger prick instead of a traditional blood draw. Researchers want to see if this simple method works well for screening people who have used intravenous or nasal drugs, including those currently on medication-assisted treatment for opioid addiction. This approach could make testing faster, less intimidating, and more accessible.

Many people who use drugs face barriers to getting tested for serious infections, including fear of needles or lack of access to healthcare. A simpler, less invasive testing method could help more people get screened early, when treatment is most effective.
