Low T4, or low thyroxine levels, indicate a deficiency in the thyroid hormone produced by the thyroid gland. This condition can lead to symptoms such as fatigue, weight gain, depression, and sensitivity to cold, as T4 plays a crucial role in regulating metabolism and energy levels. Low T4 levels may suggest hypothyroidism, which can result from various factors, including autoimmune diseases, iodine deficiency, or certain medications. Diagnosis and treatment typically involve thyroid function tests and hormone replacement therapy if necessary.
Insufficient levels (low levels) of circulating thyroid hormones is the biochemical hallmark of an under-active thyroid, a condition referred to as hypothyroidism.
Free T4 is free (unbound) thyroxine.
If my thyroid T4 free blood results are dropping what does this mean?
Hyperthyroidism would be a condition in which T3 and T4 are at increased levels.
Your doctor will determine if you need to be on Armour Thyroid which is used to raise the level of T4 hormone. Speak to your physician.
I have a lowTSH,0.06 and within the normal range readings of T3,T4 I am being treated for Hypothyroidism, have weight gain problems, dry skin etc. Should my current dose of 150 be increased to 200?
i think it is turbonetics t3 was the older one t4 is newer
Do you mean T4, as in thyroid screening
Nothing. Thyroid levels are reported in terms of TSH, free T4 and total T4 level values.

T4 is the main thyroid hormone. If your levels are dropping, then your thyroid gland is not producing enough hormone or something is interfering with the hormone's action somehow. In either case, your doctor will need to determine if you need to supplement your T4 with oral medication.
it will raise t4 levels
