PD-L1 Biomarker Testing measures the amount of PDL1 on cancer cells. PDL1 is a protein that helps keep immune cells from attacking nonharmful cells in the body. Normally, the immune system fights foreign substances like viruses and bacteria, and not your own healthy cells. Some cancer cells have high amounts of PDL1. This allows the cancer cells to "trick" the immune system, and avoid being attacked as foreign, harmful substances. Current PD-L1 testing is based on immunohistochemistry (IHC) methods. Immunohistochemistry (IHC) is the process whereby antibodies are used to detect proteins (antigens) in cells within a tissue section (for instance liver, pancreas or the heart).

PD-L1 is a ligand that binds to PD-1 (programmed cell death-1), expressed on activated T cells, to evade anti-tumor responses. PD-L1 plays a role in inhibiting T cell activation and proliferation and has emerged as an important target in cancer treatment. PD-L1 protein detection by immunohistochemistry (IHC) testing is widely used as a predictive biomarker assay for anti-PD-1/PD-L1 therapies. PDL1 testing is used to find out if you have a cancer that may benefit from immunotherapy.

This analysis provides a clear view of how leading companies are strengthening their market presence, accelerating innovation, and responding to evolving industry demands.

Market Drivers and Trend -

The PD‐L1 biomarker testing market is being propelled by the rapid expansion of immune checkpoint inhibitor therapies, particularly those targeting the PD‐1/PD‐L1 axis, which have shown remarkable clinical success in treating various advanced cancers-spurring widespread demand for stratifying patients based on PD‐L1 expression to optimize treatment outcomes. Additionally, the shift toward precision medicine has heightened the importance of molecular diagnostics. Clinicians and pharmaceutical developers are increasingly emphasizing personalized approaches, using PD‐L1 testing to guide therapeutic decisions and enable companion diagnostics-especially as diagnostic technologies advance to include automated IHC systems, NGS platforms, and AI-enhanced analysis .

Despite these positive trends, the PD‐L1 testing landscape faces significant obstacles due to a lack of standardization across protocols, assay clones, scoring systems, and cut-off thresholds. This inconsistency manifests in discordant results (with variability rates reported between 19-32% across different assays), undermining diagnostic reliability and complicating clinical decision-making. Moreover, high costs associated with advanced testing techniques (IHC, NGS) and uneven reimbursement frameworks create economic barriers, particularly in developing regions, impeding broad accessibility and exacerbating healthcare disparities.

The classification of PD-L1 Biomarker Testing includes PD-L1 (22C3), PD-L1 (28-8), PD-L1 (SP142), PD-L1 (SP263) and Other, and the revenue proportion of PD-L1 (22C3) in 2024 is about 21.68%.
