BUSPIRONE, SERUM/PLASMA

Specimen Required
Draw blood in a plain red-top tube. Centrifuge, separate serum from cells and send 1.0 mL serum (0.4 mL minimum) refrigerated in a screw-capped plastic vial.
Peak serum levels are recommended when monitoring patients because the level in the blood drops so rapidly that many negative results are found at the trough. The peak occurs at 40 to 90 minutes post dose.
