    T3 uptake and FTI (Free thyroxine index)

    Hi folks!

    Many of us have dealt with clueless doctors that run outdated and useless tests.

    In fact, quite recently, I was trying to explain just what the T3 uptake and FTI tests really meant. However, due to the fact that they are calculations based upon other outdated tests and calculations, I couldn't remember just what those tests were.

    I had saved some information about these tests that were shared with me by a person who has worked in hospital laboratories for over thirty years and recently found it.

    For those of you who might be interested, here's what she had to say:

    " The FTI is an obsolete test that's actually a calculation. It uses the T3 uptake, another obsolete test which measures how well binding proteins latch on to thyroid hormone) along with the total T4 to guess-timate about how much FT4 one has.

    This test is no longer recommended since the direct measurement of free T4 (FT4 test) is more accurate. The old tests were used before methods to measure FT4 directly were developed."

    So, when we tell someone on here that a test is outdated and useless, we're not kidding.
