T3, Free (fT3) details

Description

Free T3 (fT3) measures the small, unbound, biologically active portion of triiodothyronine (T3) — the more potent of your two main thyroid hormones — available for your body's tissues to actually use. It's used alongside TSH and free T4 to evaluate thyroid function, and can be particularly useful in situations where T4-to-T3 conversion issues are suspected, or when TSH and free T4 results don't fully explain a person's symptoms, since free T3 is the hormone form most directly responsible for many of thyroid hormone's effects on metabolism.

Recurrent UTIs and Bladder Infections: The Hormonal Connection Every Woman Should Know

Recurrent bladder infections affect millions of women and are one of the most common reasons for repeated antibiotic use. While bacteria are responsible for causing urinary tract infections, the question often remains: why do some women continue to develop infection after infection while others rarely experience one? The answer may lie in the body’s own…
