Normal nailfold capillaroscopy

- Density
- Preserved in interpretable fields

- No characteristic giant capillaries
- Architecture
- Organised distal row
Morphological description
Describe distal row, loop shape and density; minor variations are not necessarily pathological.
Causes and diagnostic direction
A normal appearance occurs in healthy individuals and may accompany primary Raynaud phenomenon.
Differential diagnoses
Distinguish a normal field, non-specific abnormality and scleroderma pattern using the complete criteria.
Pitfalls and limitations
Density and diameter cannot be quantified without calibration; poor visibility does not constitute a normal result.
Take-home message
Conclude from a good-quality, multi-field examination and integrate clinical probability.
