Measurement Units for Medical Tests
Concentration Units:
* Most of the world: Molar concentration (mol/L)
* United States: Mass concentration (g/dL or g/L)
* Some countries: Deciliters (dL) as the denominator (e.g., Sweden)
Enzyme Activity Units:
* Internationally (IU): Based on biological activity or effect
* Sweden: Katal (kat)
Reference Ranges for Blood Tests:
* Developed in the field of clinical chemistry, which analyzes bodily fluids.
* May vary between laboratories due to equipment and methodological differences.
* Interpreted in relation to laboratory-specific reference ranges, regardless of units used.
Updating Measurement Units and Reference Ranges:
* In Medical Tests Analyzer interface:
* Select a parameter to update (e.g., Rheumatoid factor).
* Adjust measurement unit naming and reference interval.
* Click the button to open the 'Reference Ranges' interface.
* Update the parameter's reference range and measurement unit name as needed.
Note: Reference intervals may also vary regionally.
DDxHub is a concentrator that holds a lot of disease descriptions. It relies on the System knowledgebase to diagnose a health condition.
Differential diagnosis Hub is the System distinguishing of a particular disease or health condition from others.
