Question 1

tsh thyroid stimulating hormone is 2.380 is that normal?i know it is suppost to be between 0.30 4.70 acceptable range but don't understand it still

Accepted Answer

Thyroid test: Tsh is a hormone released by the pitutary gland and is negatively cycled in response to thyroid hormone levels, high levels of thyroid cause a drop in TSH and vica versa.
The range of TSH is affected by physiological factors such as sleep , circadian variation, food intake and sleep but within the narrow range you quote
there is also variations due to measurement called interassay variation.

Question 2

can you have a thyroid problem if you have a normal thyroid-stimulating hormone (tsh)?

Accepted Answer

Yes: The 'normal' TSH level is determined statistically, not clinically. Some people in the upper part of the 'normal' range will have symptoms and will benefit from treatment. This is similar to people on thyroid hormone treatment who have an increase in tsh, due to further failure of the thyroid, report recurence of symptoms and improvement with adjustment of their treatment.

Question 3

triiodothyronine : 0.76 ng/ml; thyroxine : 5.27 ; thyroid stimulating hormone : 1.15. is this normal?

Accepted Answer

Probably: In interpreting thyroid hormone levels, you have to consider several things:  What is the clinical situation at the time of the lab draw- as stress, medications, even pregnancy can all effect the levels and what they should be.  Every lab also has a slightly different 'normal' range depending on how they measure the hormone. Seeing the trend also helps - Are they stable, going up or down?

Question 4

what is the normal level of thyroid-stimulating hormone (tsh) in the blood of a 40 year old male?

Accepted Answer

Some controversy: Most labs use the reference range of 0.5 - 4.70 or 5.0 miu/l for "normal". However, the american association of clinical endocrinologists (hormone specialists) recommend a narrower range: 0.3 - 3.0 your doc can advise you which reference range s/he follows.

Question 5

these are my thyroid stimulating hormone (tsh) results can you please explain thank you

my value 2.31 mciu/ml	standard range 0.35 - 4.00 mciu/ml?

Accepted Answer

Normal: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Talk to the doctor who ordered the tests. Having said that, your result is in the normal range.
Have a healthy diet, exercise, drink plenty of water, have safe sex, if you do, and get HPV vaccine.

Question 6

my dad is worried because his thyroid stimulating hormone (serum) is high (5.370) but free t4 (serum) is within range (14.80). please explain and help?

Accepted Answer

Ranges?: The TSH is slightly high but and free T4 of 14.80 (if that is not an error) is high.  You say his free T4 is normal, however if this the case, he may have what we call subclinical hypothyroidism.  Further testing may be needed (thyroglobulin antibody, thyroid peroxidase antibody) before any decision to treat can be made.

Question 7

38 year old female fatigue brittle hair and hair drop. weak nails, peeling apart in layers. did a thyroid stimulating hormone test and the number is on the very low side of normal (1.10 for last test) should i be worried about how low the number is?

Accepted Answer

: Lab tests are a snapshot in time, an instant win an ongoing video. Discuss all of your lb tests wqithyour ordering Physician and their meaning as part of the totality of your health.

Question 8

what is thyroid stimulating hormone?

Accepted Answer

Thyroid regulator : It's the hormone from the pituitary gland that makes the thyroid work harder.

Question 9

where is the thyroid-stimulating hormone produced?

Accepted Answer

Pituitary Gland: Tsh (thyroid stimulating hormone) is made in the pituitary gland, which lies just below the brain.  The brain and pituitary monitor circulating levels of thyroid hormone.  If thyroid levels are low, the pituitary releases higher levels of TSH to get the thyroid gland to make more thyroid hormone.  If thyroid levels are high, lower levels of TSH provide less stimulation to the thyroid.

Question 10

what happens when thyroid stimulating hormone goes up?

Accepted Answer

TSH increase: Thyroid stimulation hormone (TSH) is released by the pituitary gland in response to the amount of thyroid hormone sensed in the blood.  If the blood level of thyroid hormone is low then the pituitary increases the amount of TSH into the blood in order to get the thyroid to release more thyroid hormone.  Therefore a rising or increasing TSH may indicated a failing or under functioning thyroid.
