    Summary

    A new direct method accurately determines free Testosterone (F.Te), aiding in diagnosing hyperandrogenism. This F.Te measurement achieved 93.1% diagnostic accuracy in patients with Polycystic Ovary Syndrome.

    Area of Science:

    • Endocrinology
    • Clinical Chemistry

    Background:

    • Hyperandrogenism is a common endocrine disorder.
    • Polycystic Ovary Syndrome (PCOS) frequently presents with hyperandrogenic symptoms like acne and hirsutism.
    • Accurate measurement of free Testosterone (F.Te) is crucial for diagnosis.

    Purpose of the Study:

    • To introduce and validate a novel direct method for free Testosterone (F.Te) determination.
    • To assess the diagnostic utility of F.Te measurement in identifying hyperandrogenism.

    Main Methods:

    • A direct assay was developed for F.Te measurement.
    • The method was applied to a control group (12 healthy men, 21 healthy women).
    • The method was also applied to a patient group (29 women with PCOS and clinical hyperandrogenism).

    Main Results:

    • The study involved healthy controls and PCOS patients exhibiting acne and hirsutism (95% of cases).
    • Determination of free Testosterone (F.Te) levels was performed using the new direct method.
    • The F.Te measurement demonstrated a 93.1% correct endocrinological diagnosis rate for hyperandrogenism.

    Conclusions:

    • The proposed direct method offers a reliable approach for F.Te quantification.
    • Accurate F.Te determination is a valuable tool for diagnosing hyperandrogenism.
    • This method shows significant potential for clinical application in endocrinology.
