Thyroid blood test results?

Question

I had blood tests to test my thyroid function. I got the lab results today in the mail. It said that my thyroid function is at a 3.48, but that's all it said. I do have a doctors appointment on Tuesday, however, I would like to know what this means now, so I can be better informed when I see the doctor.

Thanks.

(Please, only answers from people who know what I am talking about, and who know what they are talking about. No points seekers (idk trolls) please)

I had all tests done at the same time, along with a 2 hour blood glucouse test, and a few other tests. I am worried that something is wrong, because the blood glucouse results are missing from the lab results paper I was sent, and there is a note from my doctor at the bottom that I be sure to come in for my appointment on Tuesday to disscuss results and treatment options..... I would call the doctor, but they are closed for the weekend.

Answer 1

There are several different thyroid tests- TSH, total T4. free T4, and T3. The normal results vary for each one.
TSH - 0.3 to 3.0 - less than 0.3 can indicate hyperthyroidism; over 3.0 can indicate hypothyroidism
total T4 - 4.5 to 12.5 - less than 4.5 can indicate hypothyroidism. Greater than 12.5 hyperthyroidism; low T4 with low TSH can indicate pituitary problem.
free T4 - 0.7 to 2.0 - less than 0.7 can indicate hypothyroidism.
T3 - 80 to 220 - less than 80 can indicate hypothyroidism.
Doctor will have more info for you.

Answer 3

The lab range for TSH varies lab to lab. Some labs like Quest have the range at 0.3 to 5.5, other labs are much lower. AACE recommeded the range be 0.3 to 3.0, which would make the 3.48 reading you have make you hypothyroid. If you are having symptoms, then have it treated with thyroid medication. A TSH over 2.0 is doing damage in the body. see links below.

Because TSH is constantly changing throughout the day, its best to always test first thing in the morning each and every time. That way you will catch it at its high point and have the medication adjusted by the high levels. Better thyroid tests are the free t4 and free t3. THese tests are often use when the patient is on a medication that is both T4 and T3.

Answer 4

There are 3 parts of a thryoid test which are:
THS (Tyroid Hormone Stimulator) normal results are .3-3
Anything about this would be an indicator of Hyperthyroidism

T3
T4

Your results did not show the test that was done? Please call your doctor on Monday and find out which test was 3.48

Once you have this information---go to this websit and you can determine what the results mean

I had symptoms of hypothyroidism for years--but my lab results were always WNL (within normal limits). I had a really low temperature, incredible problems with losing wt, thinning hair. This year my tests did conclude that I had an underactive thryoid.

Answer 5

Usually TSH levels are high in hypothyroidism and low in hyperthyroidism.

I have hypothyroidism and I am on Synthroid 0.112 mg a day for the rest of my life. Without my medication, I am tired, sluggish, get constipated and my TSH level decreases. One of my symptoms that I notice constantly even with the medication is intolerance to cold. The lowest it has been is 0.21. The range for a TSH is 0.4 to 4.2. You are still in the normal range, but the doctor will probably keep an eye on it and have you come in for another blood test at 3 months or 6 months. I have my TSH checked every six months and so far so good. Here are some websites.

A few months ago, I was very sick, zero energy, freezing cold, depressed, weight gain, thought I was dying. I read every word of this Hypothyroidism Revolution program and followed all the advice. My life turned around the first week. I started to feel human again. Within weeks my energy came back and I felt like living again.

Answer 8

Just went in Friday for my yearly test,last test was 3.15 and considered good. I am hypo-thyroid and on synthyroid, .05
micrograms once a day. Yours would appear normal,if you have a print out and you should, you should be able to see the range is between 1 and 5. I can recommend webmd for any other questions. BTW I went in for testing after my heart
was racing when I was relaxing at 7pm.
Hope this helps,Good Luck,they normally just ck TSH level.

Answer 10

Thyroid studies are not usually done for an annual physical, so I suspect the doctor found reason to ask for this test. He could be slightly hyperthyroid, and catching it early means you have a good doctor. If the levels are just above normal, they may want to take the position of watchful waiting. If they are markedly above normal, he will need to have that treated, as hyperthyroidism is an unpleasant disease, with some bad side effects mentally and physically. Graves' disease is one of several forms of hyperthyroidism that eventually causes the eyeballs to protrude, and that symptom in itself can cause ocular problems. Interestingly, both George H.W. and Barbara Bush ( Jorge and Babs, I call them) had that while in office. While it is not a dire emergency, it is something that needs to be attended to in a timely fashion. Left unchecked, the most dramatic form is thyrotoxicosis, or thyroid storm, which can be fatal.
