Date of Service Policy For Lab Tests

General Rule: The Date of Service (DOS) of the test shall be the date the specimen was collected.

Variation: If a specimen is collected over a period that spans two calendar days, then the DOS shall be the date the collection ended.

Exception: If a specimen was stored for more than 30 calendar days before testing (otherwise known as “an archived specimen”), the DOS of the test shall be the date the specimen was obtained from storage.
