Also known as: BOB1 IHC

Clinical Use

Order Test

Use

This test is used for staining tissue samples to identify the presence of B Cell Specific Octamer Binding Protein-1 (BOB-1). It assists in the diagnosis and classification of certain B cell lymphomas by highlighting B cells within tissue sections using the immunohistochemistry method. The presence of BOB-1 can be an important factor in determining the nature of lymphoproliferative disorders.

Limitations

This test has not been cleared or approved by the FDA and is considered a laboratory-developed test (LDT). The assay is intended for use in a clinical laboratory setting and the interpretation of results should be made within the context of the larger clinical picture. The staining and interpretation require professional expertise and the test is performed as a stain and return (technical) service only, meaning no clinical interpretation is provided as part of the service.
