Executive Summary & Core Metrics
The ROS1 Immunohistochemistry (IHC) Test is a specialized laboratory assay that detects ROS1 protein overexpression in formalin-fixed paraffin-embedded (FFPE) tumor tissue, primarily to identify patients with non-small cell lung cancer (NSCLC) who may benefit from targeted therapy with crizotinib or entrectinib. This test uses monoclonal antibody D4D6 immunostaining and follows DHA guidelines for precision oncology.
Test Overview & Methodology
This assay employs validated immunohistochemical staining techniques on FFPE tissue sections. The monoclonal antibody D4D6 targets the ROS1 protein, with results interpreted by board-certified pathologists. Sensitivity and specificity are optimized for NSCLC screening.

Physician Insight & Safety Protocols
"ROS1 IHC serves as an effective screening tool for identifying potential candidates for targeted therapy. However, confirmatory testing via FISH or NGS is essential before initiating treatment. Our diagnostic pathway ensures accurate classification and guides oncologists in making informed therapeutic decisions."

Patient FAQ & Clinical Guidance
1. What is the ROS1 IHC test used for?
Answer: The ROS1 IHC test detects ROS1 protein in tumor tissue, aiding precision lung cancer treatment decisions. It is primarily used in non-small cell lung cancer to screen for ROS1 rearrangements. A positive result suggests eligibility for targeted therapies such as crizotinib, but confirmation by FISH or NGS is strongly advised. The test requires a formalin-fixed paraffin-embedded (FFPE) tumor sample and your clinical history.
2. How do I prepare for the ROS1 IHC test?
Answer: No dietary restrictions, medication changes, or fasting are required. Simply bring your doctorโs referral, the original histopathology report, and details of the biopsy location. Our specimen logistics team will handle the secure courier transport for the FFPE block or tissue sample.
3. When will I receive my ROS1 IHC results?
Answer: Turnaround time varies by sample type: 5 working days for standard FFPE blocks, 7 working days for large or complex tissue specimens. Reports are securely delivered electronically and include a telephonic consultation for result explanation.
