Tsh Cascading Reflex
Tsh w/ reflex test read 1.20 and the range was 0.27- 4.20. Is this low norm or healthy norm? I was already diagnosed with hypo earlier this yr.
Need more info: The TSH level needs to be looked at in the context of your other thyroid levels. If you are not on any medication this might be interpreted as normal but your level of free T4 and free T3 as well as your thyroid antibodies need to be analyzed as well. If your free T4 and/or free T3 levels are low, then the TSH level might not be reflecting exactly what is going on with your thyroid. ...Read more
Not a problem: Although a TSH of 0.46 is slightly below the normal range, I have never seen a patient with a similar TSH who needed any treatment. Most likely your T4 level is fine and i would view the TSH as a normal variation which has no significance for your health. ...Read more
Hypothyroidism: Normal TSH is typically 0.45-4.5. Best to discuss results w/ordering physician as some labs have different reference ranges. Regardless, if you have signs & symptoms of hypothyroidism (underactive thyroid = http://www.mayoclinic.org/diseases-conditions/hypothyroidism/basics/definition/con-20021179), prescription levothyroxine will help relieve symptoms but requires close & regular monitoring. ...Read moreSee 1 more doctor answer

Normal: That's a normal value. That's why they didn't have to run the free t4. Reflex means they will run ft4 only if tsh is abnormal. ...Read more
My tsh, w/reflex to FT4 results was 4.53 and a month later was 4.49. Do I neef to be on medication?
It is better: if you stay on it for a while. Endocrinologist like tsh between .3-3 not .5-5. Discuss with your doctor and see what your doctor will say. ...Read more
High normal: A TSH of 4.06 is in the upper range of normal. The lab probably did not do the ft4 level, since the TSH was normal. Most people with these results feel perfectly normal. However, it could be a sign that your thyroid is starting to fail. It would be reasonable to repeat the TSH and do a free T4 level in a few months. ...Read more
