What Is Transection & Growth Rate?
Transection is the loss of follicles when removed from the donor area. This occurs because the follicular unit becomes damaged when being removed; an acceptable transection rate is approximately 5-7%. The growth rate is the % of follicular units that grow once placed in the recipient area. The yield is compromised if the FU are not placed correctly, stored effectively or damaged when being placed; an acceptable growth rate is approximately 94-98%.
