Rapid microarray (CGH and SNP)
- 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.: GTR000525320.9

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.After identification of a copy number gain or loss, FISH confirmation/visualization is attempted for majority of findings if specimen is adequate. 000 For specimen requirements and handling instructions please visit: https://www.allelediagnostics.com/ordering/sample-requirements/.
