Count the pipes to find a field, and count the empty ones too: an empty field still holds its place. Leave out the separator before VAR-2 and its value arrives as VAR-1, so the receiver stores Documented Date/Time as Variance Instance ID.

This page carries the VAR field table as published and nothing beyond it. The field notes, vendor behaviour, FHIR mapping and parsing guidance that thePID page has are still to be written for VAR.
