Know more about this test
The PDL-1 22C3 Dako test is an advanced diagnostic test used to measure the expression of the PD-L1 protein on tumor cells. It helps determine whether a patient may respond well to immunotherapy drugs such as pembrolizumab (Keytruda). This immunohistochemistry (IHC)–based test uses the Dako 22C3 pharmDx assay, an FDA-approved companion diagnostic, to detect and quantify PD-L1 levels in tumor tissue. Results guide doctors in personalizing cancer treatment plans, selecting patients likely to benefit from PD-1/PD-L1 inhibitors, and improving clinical outcomes. This test is widely available with Tata 1mg labs at an affordable price in Ranchi.
Disclaimer: In no event shall the liability of TATA 1MG exceed the amount of the actual cost of test charges incurred by the customer as stated on the invoice issued by Tata 1mg.
