Programmed death-1 (PD-1) IVD, antibody

Programmed death-1 (PD-1) in vitro diagnostic (IVD) antibody tests detect the presence or levels of the PD-1 protein (CD279) in biological samples, such as blood or tissue. These tests support cancer diagnostics, particularly in assessing immune checkpoint expression for personalized treatment planning, like immunotherapy eligibility.

These devices are typically classified as in vitro diagnostics and regulated under relevant medical device laws, with requirements varying by jurisdiction. They are generally supplied as kits or reagents for laboratory use, requiring proper handling and validation in clinical settings to ensure accurate PD-1 detection.
