This blood test measures Iron and Total Iron-Binding Capacity (TIBC) levels. The total amount of iron bound to transferrin is known as Total Iron-Binding Capacity (TIBC). The body makes transferrin in relationship to the need for iron.
This blood test is used to measure total circulating estrogens. The three major naturally occurring estrogens are present in significant quantities in blood. They are estradiol (E2), estrone (E1) and estriol (E3). Because estradiol and estrone fluctuate during a womanâ€™s cycle and menopause, some providers prefer this test when evaluating estrogen levels. Estrogenâ€™s role in supporting health and well-being is as significant as it is diverse. To name a few, estrogen affects emotions moods, attention and language skills.
