TLE-1 Immunostain, Technical Component Only
Use
Transducin-like enhancer of split proteins (TLE-1) associates with chromatin, specifically with histone H3. TLE1 is upregulated in early stages of cell differentiation and may have value in the diagnosis of synovial sarcoma, where it is positive in the majority of the cases. However, this marker is not entirely specific for synovial sarcoma, and results should be interpreted in the context of other clinicopathologic and immunophenotypic features.
Special Instructions
This test includes only technical performance of the stain; no pathologist interpretation is provided. Technical component only stains should not be ordered with PATHC / Pathology Consultation. If ordered with PATHC, the technical component stains will be canceled. Any immunohistochemistry (IHC)/in situ hybridization (ISH) stain performed as a part of the PATHC will be performed at the reviewing pathologist's discretion at an additional charge.
Limitations
This test does not include pathologist interpretation, only technical performance of the stain. If interpretation is required, order PATHC / Pathology Consultation for a full diagnostic evaluation or second opinion of the case. The positive and negative controls are verified as showing appropriate immunoreactivity. Interpretation of this test should be performed in the context of the patient's clinical history and other diagnostic tests by a qualified pathologist.
