Longitudinal Specimen Collection
Watch Video
Overview
In longitudinal collections, specific time points for collection, specimen requirements, and processing details are defined at the start of the study. The planned collection workflow of OpenSpecimen allows you to define study calendars and SOP for the study.
While these specimens are ‘expected’ to be collected for each participant in some cases, there might be ‘deviations’ that can be handled during specimen collection.
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
Prerequisites
Refer to https://openspecimen.atlassian.net/wiki/x/EgB9 page for details on configuring the 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.
Collecting pending specimens
Example scenarios:
The visit may be created on the previous day of the surgery and the specimens are collected post-surgery. The user will add a visit first and collect the pending specimens later.
The collection site sent 2 tubes on day 1 and the other 2 tubes on day 2. In this case, the user will collect the first 2 tubes first and collect the pending specimens later
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 the 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.
