have just found a website on lab tests which has made it all a bit clearer. The only abnormality I have is my FSH/LH ratio which is about 2:1 and should normally be 1:1. see below for the all the info I found:
Laboratory Tests
FSH (Follicle Stimulating Hormone), will be normal or low with PCOS
LH (Lutenizing Hormone), will be elevated
LH/FSH ratio. This ratio is normally about 1:1 in premenopausal women, but with PCOS a ratio of greater than 2:1 or 3:1 may be considered diagnostic
Prolactin will be normal or low
Testosterone, total and/or free, usually elevated
DHEAS (may be done to rule out a virilizing adrenal tumor in women with rapidly advancing hirsutism), frequently mildly elevated with PCOS
17-ketosteroids (urine metabolites of androgens, used to evaluate adrenal function) elevated or decreased?
Estrogens, may be normal or elevated
Sex hormone binding globulin, may be reduced
Androstenedione, may be elevated
