Hi Mutasim,
The glucuronide is much more hydrophilic than the parent. No way to extract both together in sample preparation (not to speak about having them in the same chromatographic run – unless you apply an aggressive gradient elution). Hence, use glucuronidase. This gives you the total.
Total.
❝ Does it mean measuring each one alone? or the total as in FDA guidance?

❝ CI be for each one alone or both unconjugated and total or only total?
Total.
