Should I have any hormone tests done?
Blood tests include female and male sex hormone levels as well as thyroid function, as part of the diagnostic workup.
The majority of women affected by FPHL do not have underlying hormonal abnormalities. However a few women with FPHL are found to have excessive levels of androgens. These women tend also to suffer from acne, irregular menses and excessive facial and body hair.
These symptoms are characteristic of polycystic ovarian syndrome (PCOS) although the majority of women with PCOS do not experience hair loss. Less often, congenital adrenal hyperplasia may be responsible.
