Clinical
Indications |
|
DHEA-S
is useful in the diagnosis of a virilizing adrenal tumour and
to monitor recurrence after surgical removal. It is of little
value in the investigation of acne, idiopathic hirsuitism or
infertility.
DHEA-S is the first adrenal androgen to show a significant
increase at the onset of adrenarche and serum levels give an
indication of the stage of development in children and may be
useful in the investigation of delayed or precocious
adrenarche / puberty.
