Slender loops with an irregular peripheral tip

Slender capillaries with occasional angulated limbs and unequal apical widths. An irregular loop is partly visible at the right edge.

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.
