The test is intended for use in conjunction with endoscopy and other clinical information to assess the likelihood that EBV-associated nasopharyngeal carcinoma (NPC) is present. The test is indicated for use in adults of Chinese descent with signs and symptoms of nasopharyngeal carcinoma.
The NP Screen assay is a single-site assay performed at Primex Clinical Laboratories, Inc.
