TESTS AVAILABLE

  •  Standard Tests

 Hormone levels are measured in order to properly diagnose hyperthyroidism, menopause, andropause, adrenal fatigue and other hormone-related complaints. They exhibit symptoms that are similar and overlapping across several conditions that if a diagnosis is made based on symptoms alone, it is often inaccurate. Hormone testing is a powerful tool to eliminate doubts and provides the medical community with exactly the kind of information they need when deciding on a course of treatment for hormone imbalance.

Hormone imbalances are quite common occurrences and if the symptoms are mild enough, they are often dismissed and not given due notice. Over time however, if they are not identified accurately, it may lead to inappropriate treatments that can be seriously detrimental to one’s health in the long run. The importance of monitoring one’s hormone levels cannot be overstated enough.
