The second type is a more general test for variants. This type of test returns the identity of variants found in a certain region of the genome.\n\nThe identity of non-genomic laboratory tests is typically represented by a LOINC code. However, many genetic tests and panels do not have LOINC codes, although some might have an identifier in NCBI Genetic Testing Registry (GTR), a central location for voluntary submission of genetic test information by providers. To identify the diagnostic report, the name of the report must be in the text sub-field of the code structure. If there is a coded identifier from GTR, LOINC, or other source, then it should be included into the the code sub-field of the code structure. If there is no suitable code, the code can be omitted.\n\nConformance note: To be conformant to US Core, the code attribute must be a LOINC code, if available. If there is no suitable code in LOINC, then a code from an alternative code system (such as GTR) can be used.\n\nImplementation note: The performer of the test (organization or practitioner) should be included in the FHIR profile as the performer.actor.\n\nConformance note: The category for this profile is set to GE (Genetics), a code from http://hl7.org/fhir/ValueSet/diagnostic-service-sections.
