Thyroid Gland: Located at the base of the neck and makes thyroxin (thyroid hormone or T4) which signals the cells to make energy. Adrenal Glands: Located on top of the kidneys, they make many hormones (Cortisol, DHEA etc.).It is an approximation. Nonetheless, as a clinical tool, it seems to be more informative than the alternative which is to call a lab value low, normal, or high. After using it several times, you will probably wonder how anyone can use a term like normal to describe a relationship as complex as the one.
The reason for this is that for about 4 hours after ingesting a tablet of thyroxine, the blood level of thyroxine peaks and will give a spuriously high reading". Other doctors I have asked tell me that it makes no difference.Pituitary Gland: Situated at the base of the brain (above the roof of the mouth it sends out instructions to many other glands telling them how much hormone to produce. One such hormone is TSH (Thyroid Stimulating Hormone) which signals to the thyroid gland to make thyroid hormone.
Thyroid Blood Tests (TFT - Thyroid Function Test) The blood test for thyroid problems is called a Thyroid Function Test. The most usual tests are: TSH, TT4 AND FT4 There is a range, which is used for the tests.Total T3: Reflects the total amount of T3 present in the blood, i.e., the protein bound (unavailable) T3 as well as the Free T3. Again, estrogen dominance creates the same effect as mentioned in relationship to T4 above.
NB: Dr. Toft, Consultant Physician, states in the British Thyroid Foundation newsletter Issue No. 23 that normal ranges are: T4 (10 25) and TSH (0.15 3.5). He also states that "the correct dose is that which restores good health; in most patients this will be associated with a level of T4 in the blood towards.NB: Dr Bayliss tells us in his book Thyroid Disease: the facts "Do not take any thyroxine on the day when you go for your check-up and have a blood sample taken.
In many patients with "normal" or "high" thyroid blood levels, but many clinical symptoms, the patient's blood levels actually drop lower once the patient is given thyroid hormones simply because their blood volume increases.Free T4: Reflects the biologically active (free) form of T4. This T4 can be conver.
You decide! Taken from Medicine International 1993 "The aim of thyroxine replacement therapy is to normalise plasma TSH and to achieve a clinically euthyroid state. To obtain this, FT4 and TT4 have to be maintained at, or just above, the upper reference interval".Whens the last time you went to the doctor and gave a blood sample that was then sent to a lab? Chances are that lab result came back normal. Too often, when interpreting lab values, the doctor looks for normal rather than optimal.
T4: Has four iodine atoms and it is a pro-hormone, i.e., it lives to become either T3 or RT3. T3: When the body needs energy, it removes an iodine atom from the T4 and turns it into T3 which in turn signals living cells to make energy (ATP).Example 3: Betty had mononucleosis (EBV) 10 years ago after which she developed anxiety, insomnia, coldness and PMS due to adrenal fatigue. She recently had marital stress. Thyroid lab values show are: TSH 0.9 (below optimal FT4 0.9 (below optimal FT3 260 (below optimal and lower than T4 on the relative scale) What does this.
The Thyroid Scale helps us compare thyroid lab values to each other and thus see their implications more clearly. It can be a line diagram or a table of lab values to visually depict how TSH, T4, and T3 relate to each other.Joint pains and muscular pains. Did you know that the thyroid becomes more effective in the summer? So if your symptoms come back a bit in the winter, you may need a slightly higher dosage of your hormone replacement.
Free T3 Index FT3I 80-180 Radioactive iodine uptake RAIU 10-30. Serum thyrotropin TSH uU/ml Thyroxine-binding globulin TBG 12-20 ug/dl T4 1.8 ugm. TRH stimulation test Peak TSH 9-30 uIU/ml at 20-30 min Serum thyroglobulin l.Example 1: John is healthy and coming in for an annual physical. Thyroid lab values are in the optimal range (see the thyroid scale below) with TSH 1.5 (optimal FT4 1.26 (optimal FT3 322 (optimal).
Tg 0-30 ng/m Thyroid microsomal antibody titer TMAb. Varies with method Thyroglobulin antibody titer TgAb. Varies with method Updated on.It represents the pituitary's need or desire for more thyroid hormone (T4 or T3). Thus a high TSH level is like the pituitary saying it has a high need for thyroid hormone or the body can tolerate more thyroid energy than it is getting and it is meant to generate more thyroid hormone production.
