FUE Graft Quality Control and Microscopy
Microscopic assessment of partial injury and perifollicular tissue, and the distinction between visible integrity and biological viability.
Short answer
Graft quality cannot be measured by numerical graft production alone.[1][2]
Anatomy and biomechanical mechanism
Hair follicle count, complete or partial transection, perifollicular tissue and signs of mechanical crushing can be assessed.[1][2]
Risks and limits of the evidence
Microscopic appearance is not a definitive viability test; metabolic function and twelve-month growth are separate outcomes.[1][2][3]
Clinical assessment and quality control
Standardised injury classification and outcome follow-up can support quality improvement.[1][2]
KSD planning note
Visible injury classification, counting methods and follow-up findings are recorded separately. A microscopic image alone does not yield a definitive growth percentage.
Topic-specific questions
Is a graft that looks intact definitely viable?
Visible integrity is favourable, but does not alone prove metabolic function or long-term growth.
Does quality control only count grafts?
No. Follicle count, injury type and tissue condition may also be assessed.
