Notes
The recorded date on which participants submitted their test results, either via web form or an automated interactive voice response (IVR) call.
Postal returns have no recorded date of submission as it was not possible to tell how long they had been in transfit and processing delays (e.g. weekends) meant that the data was not always transcribed electronically on the same day it arrived physically - such entries are flagged using Data-Coding 1642.
Coding 1642 defines 1 special value:
- 1999-01-01 represents "Data returned via post"
