Results outside the reference range do not necessarily indicate disease. Similarly, results within the reference range do not preclude abnormality. Please contact the Duty Biochemist for discussion of individual patient results.

Assessment of ovarian function in females, or gynaecomastia in males.


Levels fluctuate from day-to-day and throughout the menstrual cycle, single measurements are rarely of value and FSH is a more reliable test. Serial levels are informative for assisting IVF cycles.

There are a number of non-pathological factors that can influence levels of specific analytes, giving falsely elevated or reduced levels. If you require more information regarding the effects of these factors on the individual test results, please contact the Duty Biochemist.

Serum/plasma samples are routinely screened for the presence of haemolysis, icterus and lipaemia. Results are not reported if one or more of these has been detected at levels deemed to have had a significant impact on the accuracy of the test.
