Abnormal assays such as this one should have specific phenotypic subclasses. When we have better representation of the assays, we can create the appropriate class restrictions, but for now would be good to try to include more abnormal phenotypic assay outcomes.
Similarly, classes such as 'Gastrostomy tube feeding in infancy', where a device is used to address a specific phenotype, have similar issues.
Diff:
I have added Reduced ejection fraction (with 3 children) and Regional left ventricular wall motion abnormality, again stating in the main definition that morphological abnormalities should be coded using terms fromthe morphology hierarchy. These abnormalities can be visualized with other modalities as well, but are usually investigated by echo. At some point, we might want to develop a better way of encoding test results, but I think this is a reasonable solution for now. This area can be expanded, feedback please.
