Cancer-Associated Retinopathy Panel (CARP) by Immunoblot and IHC
Use
The Cancer-Associated Retinopathy Panel (CARP) is used to investigate the presence of antibodies associated with cancer-associated retinopathy. This test involves using immunoblot and immunohistochemistry (IHC) techniques to detect these antibodies, which can be indicative of a paraneoplastic syndrome affecting vision. CARP can be part of a broader diagnostic evaluation for patients presenting with visual symptoms potentially associated with an underlying cancer.
Special Instructions
Not provided.
Limitations
This assay may not detect all possible antibodies associated with cancer-associated retinopathy. Test results should be interpreted in the context of clinical findings and other diagnostic tests. The procedure is limited by the specificity and sensitivity of the immunoblot and IHC methods used.
