Question 1

what is a "tsh reflex" test?

Accepted Answer

Weird terminology: As best i can tell, it is just a TSH with ft4.  Not sure why someone calls it "tsh reflex".  Maybe the lab does the tsh, and then does the ft4 if the TSH is abnormal.

Question 2

understanding what my tsh reflex level of 5.25 h means?

Accepted Answer

: Usually if the TSH is abnormal the lab automatically performs a free T4 level as a reflex response so that the clinician gets the result sooner&amp; can validate whether the thyroid is overactive or underactive immediately. A TSH between 0.4 to 5.0 is normal. Your reading of 5.25 is borderline high&amp; could indicate a mildly underactive thyroid in which case your free T4 will be abnormally low(under0.7)

Question 3

tsh, 3rd generation with reflex is 0.46 - what does this mean?

Accepted Answer

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.

Question 4

my husbands tsh reflex with frt4 is 0.047.  is this dangerous, and what should we be doing?  are there symptoms with this?

Accepted Answer

: 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, if the value you provided is the TSH level, it indicates thyroid hyperactivity.

Question 5

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.

Accepted Answer

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 (liothyronine) as well as your thyroid antibodies need to be analyzed as well. If your free T4 and/or free T3 (liothyronine) levels are low, then the TSH level might not be reflecting exactly what is going on with your thyroid.

Question 6

is tsh w/reflex to ft4 4.06 normal?

Accepted Answer

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.

Question 7

my tsh w/reflex to ft4 is 1.73
miu/l  what does this mean?

Accepted Answer

Normal: TSH value appears normal per most labs ranges. All labs should be interpreted in the individual context otherwise.

Question 8

my tsh w/reflex to ft4 results are 15.44. what does this mean?

Accepted Answer

HYPOTHRYOID: Your thyroid gland is underactive it is not producing enough thyroxine. The pituitary gland is working overtime to try to get the thyroid gland to produce enough thyroxine which regulates the bodies metabolic rate. You need supplementation of what your gland produces. You also need to be checked for autoimmune thyroiditis, see your doctor.

Question 9

if my tsh w/ reflex to ft4  is  5.05 what needs  to  be  done  to lower it?

Accepted Answer

Thyroid evaluation: You need an overall thyroid gland function evaluation and that will determine the appropriate treatment

Question 10

i had a tsh w/ reflex to ft4 with a result of 1.09 mlu/l what does this mean?

Accepted Answer

Normal: This is a completely normal TSH.  The free T4 was not done because the TSH was normal indicating normal thyroid function and the FT4 is not indicated.

There are some rare circumstances when you would do both, and not just the reflex, but in general a normal screening TSH means normal thyroid function. Anything else would specifically being looked for and thyroid testing can rarely be complicated.
