days from now is used to calculate the date some number of days after the date of the current episode. This is mostly used to give very specific comments, for example to recommend a further test.
For example, given the following case fragment,
01 Jun 03 20 Jun 03 03 Sep 03 15 Oct 03 02 Nov 03 ABC 2.5 2.3 2.2 2.1 2.0 DEF 6.3 4.0 1.9
The following conclusion could be added:
Next assay due in 14 days on {14 days from now}.
This would be evaluated in a report as:
Next assay due in 14 days on 16/Nov/03.
