Hormone levels can vary depending on time of day, menstrual cycle phase, age, and individual factors. Reference ranges on your report take many of these variables into account, but clinical context is important for interpretation.

If your hormone levels are outside the expected range, we recommend discussing your results with your GP or an appropriate specialist, who can advise on any further investigation or treatment.
