Testosterone & Oestradiol
Total testosterone is a quantitative marker of your current circulating testosterone level. Testosterone is broken down in part to oestradiol. You need a healthy oestradiol level for libido, bone and cardiovascular health. An excess or deficit of oestradiol can cause symptoms such as breast enlargement and tenderness, altered libido, water retention and joint pains. This test is most useful for people already on testosterone replacement therapy.
