Classify the pattern and choose follow-up

Interpretation of a mixing study is only as sound as three checks performed in order: is a mixing study indicated and is the specimen and drug history clean, what does the immediate result show against the local rule, and what does the incubated result add. Skipping any one of those checks risks calling a drug-interference pattern an inhibitor, or calling a time-dependent inhibitor corrected because only the immediate result was read.

For this case, work through the same three checks a bench scientist would use before releasing an interpretive comment: confirm the specimen and drug review support interpreting the mix at all, use the calculated indices to classify the immediate and incubated behavior against the stated local limit, and then choose the follow-up testing that is actually indicated by a time-dependent inhibitory pattern, no more and no less.

A corrected mix that stays corrected on incubation supports a deficiency pattern; a mix that never corrects supports an inhibitory pattern with drug interference already excluded; a mix that corrects immediately but not after incubation is the time-dependent pattern worked in the guided example. Each of these leads to a different, bounded next test, not a diagnosis pronounced from the mixing result alone.

Classify the pattern from both timepoints and the specimen review together, then route to the specific confirmatory test the pattern calls for; the mixing study's job ends at classification, not at diagnosis.
