Introduction

‘Specimen Type’ is a dropdown that defines the specimens you collect in OpenSpecimenavailable list of specimens types. Each specimen type belongs to a 'Specimen class,' such as Fluid, Molecular, Tissue, Cell, and others. In the recent versions, OpenSpecimen has added the ability to create custom specimen classes and support for multiple specimen units per specimen type per Collection Protocol.

  1. From v11.0 onwards, the system will automatically pick all the specimen units defined for specimen types in the dropdown manager to the specimen units. Manual intervention is not required.

  2. If units are updated after specimens are collected, then the existing specimens won't be automatically recalculated. For example, 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.

  3. Display the unit using the following logic:

    1. Use the units specified either at the CP level or system level using the following 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.

    2. 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.

  4. There is no support for displaying specimen units in the query results view nor in the query exported CSV.

  5. 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

  6. There is no mechanism to allow the lab user to override the units for any particular or selected specimens. Any update to the unit applies to all the specimens of that type.
