Optimal use of hormone determinations in the biochemical diagnosis of the polycystic ovary syndrome.
OBJECTIVE
To investigate, using logistic regression analysis and receiver operator characteristic analysis, the biochemical diagnosis of polycystic ovary syndrome (PCOS) and if it could be improved by using an array of hormone measurements chosen to yield optimal and cost-effective discrimination between women with PCOS and healthy women.


METHODS
Retrospective clinical study.


METHODS
Outpatient clinic of reproductive endocrinology at Turku University Central Hospital, Turku, Finland.


METHODS
Fifty-four oligomenorrheic women with PCOS diagnosed by ovarian ultrasonography, and 29 healthy regularly menstruating women with normal ovarian morphology.


METHODS
Concentrations of LH, FSH, androstenedione (A), T, and sex hormone-binding globulin in serum.


RESULTS
Luteinizing hormone, FSH and A, when used in combination, were the hormonal analytes of highest clinical utility. Diagnostic sensitivity, specificity, and overall concordance of 98%, 93%, and 96%, respectively, were attained. Each of the analytes used alone yielded lower degree of discrimination.


CONCLUSIONS
Simultaneous use of the levels of LH, FSH, and A in serum can be used effectively for classification between women with PCOS and healthy women.
