Primordial Dwarfism Panel
- 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.: GTR000500225.9

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 Microcephalic osteodysplastic primordial dwarfism type II
