Thyroid test result 1.83 is the result of what test
My last thyroid test result came back from the lab reading
TSH 1.83, and I was told that meant a normal thyroid. I have never
received a report like this, and I wonder if this is correct. Can you
tell me if this a correct way to report a TSH finding?

answered Aug 24, 2009 at 04:05PMTSH = Thyroid stimulating hormone
Normal levels of TSH in adults (that are NOT pregnant) are 0.5 - 4.7 milliunits/ml
TSH (or thyrotropin) is the first line diagnostic test to evaluate thyroid gland function and to establish the diagnosis of autoimmune thyroid disorders.
HIGH levels of TSH may indicate you have a underactive thyroid
LOW levels of TSH may indicate and overactive thyroid.
There is a feedback system going on with your thyroid. If your thyroid is producing not enough thyroid, it cranks up TSH (thyroid stimulating hormone) production to stimulate the thyroid. If the thyroid is making to much thyroid hormone the body acts accordingly and makes less TSH thereby reducing the thyroid output of the thyroid gland.
So if we measure the TSH we get an idea of the thyroid output of hormone.
None of this applies to you since your levels are normal, but this why the test was ordered and this is how it is interpreted.
Hope this helps. -
0Votesanswered Aug 24, 2009 at 06:57PMYou didn't answer my question. Having had an underactive thyroid most of my life acquainted
me with those facts. I merely want to know if TSH 1.83 is a legitimate way of recording a normal
thyroid on my lab report. I have never seen this before, and was told that it meant that I had a normal thyroid. Can you please tell me if this is a correct and accepted way to report this on a
lab report. -
3Votesanswered Aug 25, 2009 at 08:33PMI think I did your question.
Again......
Measuring TSH is a legitimate way to determine your thyroid function and if it is producing the right amount of thyroid hormone.
Again normal levels range between 0.5 and 4.7
Your level of 1.83 seems to me anyway to be within that range unless I am missing something.
To sum up - your result shows you have a normal thyroid.
Let me ask you something - Who is doing these tests, your family doc or a endocrinologist. If you tell me your family doc I will tell you to stop there and go to a endocrinologist that specializes in this sort of disorder. -
0Votesanswered Aug 27, 2009 at 02:47PMAgain...You have not answeredmy quesion yet. It's not about the TSH test. It's about how to report a normal thyroid on a lab report sent to the patient. IS 1.83 a correct and customarily used way to report a normal thyroid on a lab report? I have never seen it used and I want to know if it is a legitimate form use, and when it is used. Incidentally, My report with this printed on it was sent to me by an endocrinologist. I don't have a family "doc".

answered Sep 09, 2009 at 11:55PMA TSH reported as 1.83 would generally have to have some sort of unit assignment after it (usually milliunits/ml). This would be standard, acceptable, customary and legitimate way of reporting the TSH value.
In very, very rare cases it is possible to have a TSH value in the "normal range" and still have low or high thyroid hormone levels in the blood (ie. when the TSH gland isn't working correctly). When this is suspected, at TSH and a free T4 is ordered.

Hi, its Gerry. It doesnt mean your thyroid is normal, it means that the TSH (thyroid stimulating hormone) was 18.7 on that day. "NORMAL" for a lab test, means that 95 percent of the "normal" population will test within a certain statistical range. This can be used clinically to test to see if medication is at the right dose, treatment is effective, conditions are imporving or worsening. Its another piece to the overall picture. TSH is produced in the pituitary and does not directly test the thyroid.
