OtoGenome Test for Hearing Loss (110 Genes)
- GTR Test IDHelpEach Test is a specific, orderable test from a particular laboratory, and is assigned a unique GTR accession number. The format is GTR00000001.1, with a leading prefix 'GTR' followed by 8 digits, a period, then 1 or more digits representing the version. When a laboratory updates a registered test, a new version number is assigned.: GTR000509148.10

Clinical testHelpIn the U.S., clinical tests must be performed under CLIA certification. When a lab uses the same methods for a test in both clinical and research settings, the test appears as two separate GTR records. for Hereditary hearing loss and deafness

Clinical validity
HelpHow consistently and accurately the test detects or predicts the intermediate or final outcomes of interest. Lab-provided.Not provided
Testing strategy
HelpThe lab's suggested sequence of ordering tests based on clinical scenarios. It may include information on: reflex testing including each test component, and scenarios which prompt additional components of testing; whether lab communicates interim results or automatically proceeds to further analyses; and if any components are performed in another laboratory.The OtoGenome™ Test is best suited for individuals who have a diagnosed hearing loss for which an underlying etiology has not yet been identified. For an individual with apparently non-syndromic hearing loss, this panel covers both non-syndromic causes of hearing loss as well as those which can present as non-syndromic. Onset of features associated with a syndromic type of hearing loss can be delayed or variable. Given the genetic heterogeneity of hearing loss, the OtoGenome™ Test allows for a shortened diagnostic course by analyzing 110 genes in a single test. 000 Physician must complete test requisition and submit a blood sample (see sample requirements)
