Comments:

No medication should have been taken since the previously scheduled doses (12 to 24 hours prior).

For many drugs, a 2-hour peak sample will be collected. You can consider a second blood draw 6 hours post dose to rule out late absorption, or to determine the serum half-life for certain drugs that have short half-lives, such isoniazid and rifampin.

For most HIV drugs, the preferred time of draw is a pre-dose trough.
