Introduction
‘Specimen Type’ is the most important and specialized dropdown. Each specimen type falls under a ‘Specimen class’ e.g., Fluid, Molecular, Tissue, Cell, etc. In the recent versions, OpenSpecimen has started accommodating a few commonly asked customizations. E.g., create custom specimen classes, multiple specimen units per specimen type per CP, etc.

Create custom ‘Specimen Class’ (v10.3 onwards)
Before v10.3, only 4 specimen class (Fluid, Molecular, Tissue and Cell) were supported. From v10.3 onwards you can add different specimen class like plants, microbes, etc. depending on your requirement.

With v11.x upgrade, the system will automatically pick up all the specimen units defined at individual specimen level in specimen units (dropdown as well as the Extras card). Manual intervention not required.
If units are updated after specimens are collected, then the existing specimens won't be automatically recalculated. E.g., if blood is changed from ml to μL, then the system won't change the values proportionately to μL. 1 ml won’t be updated to 1000 μL automatically. Users will have to change it manually via bulk upload.
Display the unit using the following logic:
Use the units specified either at the CP level or system level using the following fallback mechanisms: (cp, class, type) -> (cp, class, *) -> (*, class, type) -> (*, class, *)
where * represents all of that category
E.g., (cp, class, *): All specimen types of a given class for a specific CP.When specimen type is changed, use the units specified either at the CP or system level for the selected type/class using the above mechanism.
There is no support for displaying specimen units in the query results view nor in the query exported CSV
Units are not stored with the specimen or specimen requirements. Their units are auto computed based on what is configured either at the system or CP level
There is no mechanism to allow the lab user to override the units for any particular or selected specimens. Any update to the unit is applicable to all the specimens of that type.
