Tsh Test False Positive
Complex: Hi. It's unlikely "stress" can give a false positive TSH elevation, but "stress" comes in multiple flavors. If a person is severely ill (usually ICU-tpye ill or at least hospitalized), an adaptive response (unfortunately) called "euthyroid sick syndrome" can show a TSH elevation in that range during a phase of the condition. Only in a case like that. Stress like a final exam next week? No. ...Read more
I recently had a TSH test where my level was 4.86. I was pretty stressed and run-down at the time. Any chance it was a false positive as a result?
Not too abnormal:
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. Having said that, your TSH value while higher than normal does not mean that you have a disease or need treatment. Do discuss it with your doctor and you may opt to repeat the test.

Age 27. My TSH is. 006, total T-3 is 221, free T-4 is 2.70. Is there anything that could create a false positive? Like stress? Could I retest?
I m 24 and hypothyroid. Anti TPO test positive. I m struggling with fluctuating levels of TSH between hyper and hypo? My latest tsh-0.46 high ft4-1.53
Hashimoto's: Sounds like you have Hashimoto's Thyroiditis, which is an autoimmune disease. The body attacks it's own thyroid resulting in high thryoid levels initially and low thyroid levels once the the thyroid is "burned out." Sounds like you are currently Euthyroid (in the middle range and ok) on medicine. Your situation and other meds are somewhat complex and might be best addressed with a call-in. ...Read more
Is it true that elevated prolactin will produce a false tsh level on test results? Don't they go hand in hand?
No: The immunoassays for the two tests are distinct. ...Read more
My TSH is 6.2 my pregnancy test is positive. So I am one month pregnant but little worried my TSH will affect development of baby. Going to doc soon?
Blood calcium borderline out of range, borderline tsh&hyper&hypothyroid symptoms, could I still have hashimitos even with false ANA & thyroid tests?
My february blood tests showed ANA 1:80, rnp positive, CRP 5.1, TSH 1.83 also sed rate 25, mpv 12.1 what does this mean?
Just a screening: An "ana" is a blood test used to screen a person for the possibility of several autoimmune diseases. It is important to remember that this is a screening test and a positive result only indicates more testing may be warranted. No blood test is perfect, and getting to a diagnosis is usually much more complex than drawing blood. ...Read more
Blood test show thyroglobulin antibodies is high (low positive). but TSH, Free T4, and tpo is normal. Should I be concerned?
It sounds like your thyroid is functioning well right now, but the high antibody level indicates possible future autoimmune thyroiditis in the future.
I'm not sure why you had this full work up. If you are symptomatic of thyroid disease, you might want to see an endocrinologist even with your normal results. If you do not have symptoms, your doctor may want to monitor your TSH periodically. ...Read more
My pregnancy test s weak positive and my hormonal assay s TSH 2.11uiu/ml. ...Am I pregnant or not?
Blood test: If your blood pregnancy test says positive then you are pregnant. You need to look at the bhcg test which indicates pregnancy not TSH which looks at thyroid function. ...Read more
Can you have normal TSH levels & test positive for antibodies? Could thyriod antibodies be why weight & hair loss?
Can infectious mononucleosis (mono test negative- but antibodies positive- I had it in the past) be the reason for increased TSH? Is T4 necessary?
Thyroprotein/tsh level- what number is indicative of hypothyroidism? My results says 3 and normal range is 2-8. Is there another test to determine thyroid issues related to CHF? Also, is H.pylori count of 2 means positive for it? On protonixThanks.
ThryoTROPIN: Is a synonym for thyroid stimulating hormone (TSH). This hormone, produced by the pituitary gland, regulates thyroid function. Normal results for adults, in most labs, are 0.4-4.2 mU/L. This is the well-recognized/accurate test for hypothyroidism; a total thyroxine can sometimes add information. An H. pylori antibody blood test only measures past infection. Biopsy, stool antigen, breath test better ...Read more
Not much: Any lab can have a temporary problems doing any test accurately. That is why an abnormal level should always be repeated to verify it. There are temporary causes for high TSH (resolving subacute thyroiditis), so that a 2nd TSH level done a few weeks after an abnormal one, could be normal. Subclinical hypothyroidism will have a high TSH with other thyroid levels normal, no symptoms. ...Read more
Is FT4 correct?: Your TSH appears normal. Did you have a typp with the ft4, as a value of 15 is an order of magnitude too high. 1.5 would be normal. Another possibility is that the 15 is a T4 not a ft4. Either way, it's hard to tell but probably normal. Check w/your doctor. ...Read more
Normal range: You want to know the normal range for this particular lab. Probably ok but better check. ...Read more
Yes, normal: These values are all in the normal range and I would not be concerned. There is variability in the measurement, and in your biological levels. If you are taking levothyroxine, there is variation in absorption from gut, which can be minimized by taking the pill fasting, or at least being consistent with when/how you take it. ...Read more

I am taking 50 mcg thyroxin. Is it necessary to wait for 1 month to test again to check whether my TSH is in normal range?
3 weeks OK:
It takes a while for TSH to stabilize on a dose of thyroid; usually 3 weeks is adequate. Even though you don't have symptoms you may benefit from adding t3 (liothyronine) to your thyroxin. See http://bit. Ly/18atkro

If the TSH is very low like 0, 1, how long takes with the pill to the normal range? And when I have to test it again? Thank you very much.
Low TSH: What "pill" are you taking? A low TSH usually accompanies a high FT4 and suggests an overactive thyroid, with symptoms such as heat intolerance, tremor, nervous, palpitations. If you have an overactive thyroid, one treatment is methimazole/carbimazole. It usually starts to work in 1-2 weeks if the dose is adequate. ...Read more
My TSH 3rd generation test came back at 2.036. The range is 0.340-5.600uiu/m. The test said high sensitive 3rd generation tsh. What does this mean?
Not a whole lot!:
An elevated TSH is the main criteria most docs use to diagnose hypothyroidism. While most docs feel it is not abnormal unless above 5.6 or so, many endocrinologists feel anything above 3 is abnormal, and some even feel a level above 2 could indicate problems- see http://abt. Cm/1562fwq
actually, many with a totally normal TSH may still have thyroid problems- see http://bit. Ly/18atkro & comment:. ...Read more
Tsh is 6.8 but before starting meds, I want to do a FT3/FT4 test. Can I take in the evening around 430-5pm or should this be taken in the a.m. too?
Synthroid (thyroxine) in AM:
The taking of thyroid med or testing in PM and evaluation its effect is NOT necessary.
My tsh 3rd generation test results are 2.137 uIU/ml, I have a series of symptoms that bothers me a lot for 3 yrs by now, should I need more tests?
Not thyroid: The TSH is the most sensitive test for detecting either overactive or underactive thyroid problems. Your TSH is normal, and so it is very unlikely that you have a thyroid disorder causing your symptoms. ...Read more
