来自主题: Pharmaceutical版 - trough sample是什么意思?
It means the smaple is collected at the end of the dosing interval, just
before the next dose is due. For example, if it is twice daily dosing, then the
trough sample will be collected at 12hr post-dose. If it is once daily
dosing, the sample will be collected at 24hr post-dose.
It is collected to indicate the drug level at that time point is within
therapeutic window.
That's my 2cents :)

Just technical discussion.
Now matter it is internal or external radiation, the dose equivalent (SI is
Sv and traditional unit is rem.) is the same value for same amount absorbed
dose (SI is Gy, but rad is commonly used.) of one given radiation source.
Therefore, one Gy of absorbed dose of Alpha Particles can be amounted to 20
SV dose equivalent.
But, you know, the same amount SV dose equivalent will make huge differences
between internal and external radiation.
