Overview
In longitudinal protocols, the SOP for specimen collection is predefined. E.g., time point, type of specimens, quantity, and processing steps can be defined in the collection protocol.
While these specimens are "expected" to be collected for each participant in some cases, there might be "deviations" like:
The participant missed the whole event
Repeat visit for the same visit
Some specimens are not collected
Some specimens are partially collected
Additional specimens are collected
such deviations can be handled during specimen collection.
Prerequisites
Refer to this page on how to define a longitudinal collection protocol.
Collecting planned specimens
You can collect specimens of a visit based on the specimen requirements defined in the collection protocol.
The specimen collection button is available in many places to minimize the number of clicks.

Deviations
You can change the number of aliquots, specimen status, specimen quantity, etc. at the time of specimen collection.
Missed Visits or Specimens
If a specimen is not collected, you can create specimens with status "missed" for audit/reporting purposes. E.g., give a list of all missed specimens.
Collecting Additional specimens
You can create additional specimens that are not defined in the protocol. Refer to Unplanned Specimens for more details.
