## Extension: Genomic Study Analysis Metrics 

| | | |
| :--- | :--- | :--- |
| *Official URL*:http://hl7.org/fhir/uv/genomics-reporting/StructureDefinition/genomic-study-analysis-metrics | *Version*:4.0.0-cibuild | |
| *Standards status:*[Trial-use](http://hl7.org/fhir/R4/versions.html#std-process) | [Maturity Level](http://hl7.org/fhir/versions.html#maturity): 2 | *Computable Name*:GenomicStudyAnalysisMetrics |

Metrics about the sequencing analysis that was performed

**Context of Use**

This extension is used for overall, analysis level metrics. These metrics are not specific to a region that is studied in the analysis. The metrics here are specific to sequencing analysis, but others could be added if they make sense to the use case.

**Usage info**

**Usages:**

* Use this Extension: [Genomic Study Analysis](StructureDefinition-genomic-study-analysis.md)
* Examples for this Extension: [Procedure/PGXGenomicStudyAnalysis](Procedure-PGXGenomicStudyAnalysis.md)
