## Laboratory Models Overview

MyHealth@EU logical models ([MyHealth@EU Laboratory Result Report Content](https://webgate.ec.europa.eu/fpfis/wikis/x/uIe6ZQ)) refine the EHDS logical information models provided by the Xt-EHR project. These models use obligations on the logical models to highlight the elements identified by the MyHealth@EU Functional Requirements. Three types of obligations are defined based on the MyHealth@EU requirements:

* **Mandatory**: the data element must be provided
* **Required**: the data element must be provided, although exceptional justifications can be provided
* **Optional**: the data element can be completely omitted

These obligations are implemented using the following rule sets:

* `ObligationMandatory` - SHALL:handle for mandatory elements
* `ObligationRequired` - SHOULD:handle for required elements
* `ObligationOptional` - MAY:able-to-populate for optional elements

### Information Models

#### Laboratory Test Results

Laboratory test results are communicated using [MyHealthEuLabObservation model](StructureDefinition-MyHealthEuLabObservation.md). This model extends the EHDS Laboratory Observation model and is specifically designed for MyHealth@EU laboratory context.

##### Laboratory Result Report

Laboratory result report is structured using the [MyHealthEuLabReport model](StructureDefinition-MyHealthEuLabReport.md) which could be divided into several parts: document header, body and optionally it could also have various attachments.
