Every re-cut costs something: tissue you may not get back, time the surgeon spends waiting, and a second (or third) round of freezing, sectioning, and staining before you have a readable margin. Most labs treat re-cuts as a sectioning problem — a technique issue to fix at the blade. Often, though, the real problem happened earlier, when the specimen was mounted.
Where Re-Cuts Actually Start
A frozen section can only show what the mount allows it to show. If the specimen isn’t oriented so the true margin sits flat and in-plane before the first cut, the first few sections may miss it entirely — not because the sectioning was wrong, but because the setup was. By the time that’s visible under the scope, you’re already re-cutting.
This is a mounting and alignment problem, not a blade problem, and it’s the specific gap the True Margin™ Tissue Press is built to close.
What True Margin™ Actually Changes
The True Margin™ Tissue Press standardizes specimen alignment before freezing — flattening and positioning the tissue so the peripheral and deep margins sit in the same plane from the start. That’s the same manual skill experienced histotechnicians develop over years, made repeatable and less dependent on who’s on the bench that day.
In practice, that means:
- The true margin shows up in the first few sections — not the fifth or sixth, after several re-cuts have already used up tissue.
- Consistency across technicians. Alignment quality stops depending entirely on individual technique and experience level.
- Less tissue lost to trimming. Fewer re-cuts means less unnecessary tissue removed to compensate for a poor initial mount.
- Faster turnaround. Every avoided re-cut is freezing, sectioning, and staining time you don’t spend twice.
Why This Matters More in Mohs Than Elsewhere
In routine histology, a slightly imperfect section can often be repeated without much consequence. In Mohs surgery, the surgeon is waiting on the read, and the patient is on the table. A re-cut isn’t just a lab delay — it extends a procedure that’s supposed to be efficient specifically because margins are checked in real time. Reducing re-cuts isn’t a nice-to-have in this setting; it’s close to the whole point.
Pairing Alignment With the Right Mount
True Margin™ solves alignment. It still needs a specimen disc that seats correctly in your cryostat to do its job well — the two problems compound each other if only one is solved. If you haven’t already, it’s worth reading about how specimen disc compatibility affects frozen section quality alongside this.
The Bottom Line
Re-cuts feel like a sectioning problem because that’s where they become visible. Most of the time, though, the fix isn’t a better cut — it’s a better mount. True Margin™ is built specifically to get the alignment right the first time, so the read happens on the first pass instead of the third.
