Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Use
The Dako PD-L1 22C3 pharmDx™ kit is a qualitative assay intended for use in the detection of PD-L1 in formalin-fixed, paraffin-embedded (FFPE) in non-small cell lung carcinoma (NSCLC) using the Dako Automated Link 48 platform.
Special Instructions
PD-L1 testing will be delayed if the pathology report is not received.
Note: This test number is used for tracking oncology IHC specimens to the laboratory. Bill codes will be added when testing is complete based on the processes performed in the laboratory.
