What is the typical volume of an oral fluid specimen?

Explanation:
The main idea is how much oral fluid is typically collected to be adequate for testing. A common target volume for an oral fluid specimen is about 3 milliliters. This amount provides enough sample for the initial screening assay and still leaves room for potential confirmatory testing if needed, while keeping collection convenient for the person. The other options don’t fit because they refer to mass (mg) or to a different specimen type entirely (urine volume, hair), which aren’t measured in milliliters of saliva.
