PD-L1 Testing

PD-L1 testing is a laboratory process used to examine a cancer sample to see if it produces a protein called PD-L1. This protein can help cancer cells hide from the immune system. If the test shows high levels of PD-L1, patients might benefit from specific immunotherapy drugs that target this protein, helping the immune system recognize and attack the cancer. The test helps doctors decide the most effective treatment options for individual patients based on their tumor's characteristics.
