Clue to loss of sweating elsewhere.Determine location of sudomotor lesion and underlying cause by thermoregulatory sweat testing combined with direct and axon reflex sweat evaluation.Patterns of anhidrosis provide objective evidence of small nerve fiber and/or eccrine gland involvement in many neurologic and dermatologic disorders.Analysis of sweat composition continues to be diagnostic in cystic fibrosis.Determination of sweat-derived antimicrobial peptides may provide evidence of impaired innate defense in skin disorders such as atopic dermatitis and neutrophilic eccrine hidradenitis.
