- Why precise timing is the most tested concept for therapeutic drug monitoring on the Phlebotomy exam.
- How to correctly time a trough draw, which is always immediately before the next scheduled dose.

- A simple mnemonic to remember the difference: "Trough is low, just before the go. Peak is high, after it's all inside."
