Changed comment for OBX[1]-1 to ""1" NOTE: For multiplex tests, there shall be an OBX and an NTE segment for each result in the panel.

For SARS-CoV-2 reporting, the SARS-CoV-2 result must be the first OBX segment, followed by any other result OBX segments, and then the Age, Symptomatic, and Date of Onset OBX segments. Do not change the Set ID for the added NTE segments.".
