Glucose Transporter-1 (GLUT-1) by Immunohistochemistry
Also known as: GLUT1 IHC
Use
The GLUT-1 test by immunohistochemistry is used to evaluate the expression of Glucose Transporter-1 protein in tissue samples. This test can aid in the diagnosis of certain cancers and other diseases where GLUT-1 overexpression is implicated. The interpretation of staining patterns and intensity helps pathologists to determine the potential involvement of GLUT-1 in a specific pathological condition, contributing to the overall clinical assessment.
Special Instructions
The test is submitted as a stain and return (technical) service only, which requires an electronic request or the use of an ARUP Immunohistochemistry Stain Form if electronic ordering is unavailable. The tissue block or slides must be transported using an ARUP tissue transport kit, and precautions should be taken to protect specimens from excessive heat.
Limitations
The GLUT-1 IHC test is performed in a CLIA-certified laboratory as a Laboratory Developed Test, but it has not been cleared or approved by the FDA. Results should be interpreted in the context of other clinical and laboratory findings and may not be definitive on their own. The test is subject to variations based on specimen handling, and degraded or improperly preserved samples may lead to inaccurate results.
