Hi Ohlbe,

Free = unbound drug concentration
Total drug = unbound + bound (to plasma protein).

FYI, FDA has a BEBA guidance for this drug but it doesn't ask to measure free drug or total drug.

The reason I asked this q is because I emailed the lab and they told me they measured unbound drug but I have a feeling that they answered my question incorrectly.

Thx
J
