Teaching point
If a loop cannot be classified safely, it is better to declare it doubtful or non-evaluable.
Measurements and calibration
For nonbranching apices with stable automated measurements, estimated widths span approximately 10–31 µm. These are automated estimates, not manually validated measurements.
Clinical caveat
This image illustrates a visual finding and should be interpreted with acquisition quality, distribution across fingers, clinical context, and serology when relevant.
