What is T4 free blood test?
Thyroxine free index. "elevated TsH and low fT4 or fTi indicates primary hypothyroidism due to disease in the thyroid gland. a low TsH and low fT4 or fTi indicates hypothyroidism due to a problem involving the pituitary gland. a low TsH with anelevated fT4 or fTi is found in individuals who have hyperthyroidism."
What to do when TSH is high and T3 and T4 are normal?
Endocrinologists who specialize in thryoid patients know not to treat patients based only on lab values. A high TSH and normal TT3 and TT4 may indicate that there are not enough free hormones available. A FreeT3 and FreeT4 will better tell the story because inactive hormone will not be included in the results. High TSH and normal FT3 and FT4 may indicate either that your 'normal' falls outside the normal range, or that your pituitary is trying to turn your thyroid on and it is not consistently or reliably responding. It may be rollercoastering. TSH is a test that gives the average of thyroid production over several weeks. FT3 and FT4 or TT3 and TT4 tells you how much hormone is there today. If FT3 and FT4 are low one week, and high the next, the TSH results will reflect the middle/average of the two. These patients usually (tho not always) have autoimmune Hashimoto's Thyroiditis or are not eating properly. Treatment: Some doctors choose Block and Replace therapy for these conditions. Others try to raise FT3 and FT4 levels until the patient is comfortable and TSH values seem more normal.
FT3 FT4 TSH how they effect each other?

What is the reason for hematology diagnostic test TSH with reflex to FT4?
This is ordered by your health care provider to rule in or out any type of thyroid disorder.
What is a normal TSH test result?
Normal TSH levels for adults are 0.5-5.0 mU/L.
Is 0.84 tsh level in normal range?
As far as the ranges are concerned a 0.8 TSH is considered normal, however, your Dr. is the best person to advise. If you are exhibiting thyroid malfunction symptoms, it is best to do an antibody test, those are the best indicators in cases where patients FT3, FT4 and TSH fall within the normal range, but nonetheless thyroid malfunction is suspected.
What does a high result per a TSH blood test determine?
high TSH than the normal range means hypothyrodism.
What happens when FT3 is 2.72 and FT4 is 1.05 and TSH is 7.18?
T4 is storage hormone and is inactive. It is converted to T3, which is the active form of the hormone that your cells use. The tests FT3 and FT4 tell how much of the hormone is in your blood, unbound to other proteins and hormones so they can be converted or utilized by the body. TSH is the hormone from your pituitary gland near your brain that tells your thyroid to produce more hormone. A low FT4 and FT3 will result in an elevated TSH, indicating hypothyroidism - your thyroid isn't producing enough thyroid hormone. A high FT4 and FT3 will result in a decreased TSH, indicating hyperthyroidism - your thyroid is producing too much thyroid hormone. Normal levels of FT3 and FT4 may indicate several issues, including a problem with the pituitary gland itself; or a change in thyroid supplementation and testing that has occurred before TSH levels have had an opportunity to reflect those changes. There are other causes of hormonal abnormalities, but an endocrinologist will know the correct tests to use to determine a diagnosis and potential treatment for abnormalities that are found.
What does high TSH thyroid stimulating hormone levels indicate?
What does the test result mean?NOTE: A standard reference range is not available for this test. Because reference values are dependent on many factors, including patient age, gender, sample population, and test method, numeric test results have different meanings in different labs. Your lab report should include the specific reference range for your test. Lab Tests Online strongly recommends that you discuss your test results with your doctor. For more information on reference ranges, please read Reference Ranges and What They Mean.A high TSH result often means an underactive thyroid gland that is not responding adequately to the stimulation of TSH due to some type of acute or chronic thyroid dysfunction. Rarely, a high TSH result can indicate a problem with the pituitary gland, such as a tumor producing unregulated levels of TSH. A high TSH value can also occur when patients with a known thyroid disorder (or those who have had their thyroid gland removed) are receiving too little thyroid hormone medication. A low TSH result can indicate an overactive thyroid gland (hyperthyroidism) or excessive amounts of thyroid hormone medication in those who are being treated for an underactive (or removed) thyroid gland. Rarely, a low TSH result may indicate damage to the pituitary gland that prevents it from producing adequate amounts of TSH. Whether high or low, an abnormal TSH indicates an excess or deficiency in the amount of thyroid hormone available to the body, but it does not indicate the reason why. An abnormal TSH test result is usually followed by additional testing to investigate the cause of the increase or decrease. The following table summarizes test results and their potential meaning.

When your doctor adjusts your dose of thyroid hormone, it is important to wait at least one to two months before checking your TSH again so that your new dose can have its full effect. Extreme stress and acute illness may also affect TSH test results, and results may be low during the first trimester of pregnancy.

What is difference between t3 and t4 thyroid hormones?
TSH is commonly accepted today as the first-line diagnostic test for overall thyroid function. In general, a normal TSH level (0.3-4.5) indicates normal thyroid function. If the TSH is high or low, then T4 and T3 (and their "free" forms, FT4 and FT3) are evaluated to narrow the diagnosis.
What is the meaning of laboratory test?
A thyroid stimulating hormone (TSH) test is an initial test used to determine how your thyroid is functioning. A high TSH level indicates that the thyroid gland isn't making enough hormones, causing hypothyroidism. Conversely, if the TSH level is low it indicates an overactive thyroid, known as hyperthyroidism. The TSH normal level range that most physicians refer to is .3 to 4.5.
What is normal TSH level?
TSH levels show ranges. For newborns TSH normal levels should be: 3.0-20 mIU/L. For adults up to age 60 TSH normal levels should be: <10 mIU/L For adults older than 60 TSH normal levels should be: Males: 2.0-7.3 mIU/L Females: 2.0-16.8 mIU/L
