TIL Reference Ranges and Clinical Significance

TIL Level Infiltration Level (TIL Score) Clinical Significance
High (≥50%) High infiltration Strong immune response, better prognosis, more likely to benefit from immunotherapy
Moderate (10–50%) Moderate infiltration Intermediate immune response, may benefit from immunotherapy
Low (<10%) Low infiltration Weak immune response, consider alternative treatments

* Reference ranges may vary depending on laboratory methods and clinical settings. Please interpret results in combination with clinical conditions.

FAQ

Q.Does the TIL Test require surgery?

Yes. The TIL Test requires a tumor tissue sample obtained from surgery or a biopsy. No additional specimen collection is usually required.

Q.Can the TIL Test influence treatment decisions?

Yes. The quantity, activity, and distribution of tumor-infiltrating lymphocytes help physicians evaluate the likelihood of response to immunotherapy and support personalized treatment planning.

Q.Can my TIL score change over time?

Yes. TIL scores may change in response to treatment, disease progression, or changes in the immune microenvironment, making them valuable for ongoing treatment monitoring.

Q.How accurate is the TIL Test?

The test combines multiplex immunofluorescence staining, AI-powered image analysis, and pathological interpretation to provide a highly accurate assessment of the tumor immune microenvironment.

Q.How long does it take to receive the results?

Results are typically available within 7–10 business days after multiplex immunofluorescence analysis, AI processing, and comprehensive pathological review.

Q.Which cancers are suitable for TIL testing?

The TIL Test is applicable to many solid tumors, including breast cancer, lung cancer, colorectal cancer, melanoma, and other cancers where evaluation of the tumor immune microenvironment can help guide treatment decisions.
