“Is a TSH value of 3.17 normal in 9 months of pregnancy?”
I am a 36-year-old and I am 9 months pregnant. In my last blood test report, my TSH value showed 3.17. Is this considered as a normal TSH or is anything worrisome?

The blood test should be discussed with your physician. For thyroid disease most likely they will order more tests.
In pregnancy, production of thyroid hormones T3 and T4 increases by about 50%. As a result, the normal thyroid-stimulating hormone (TSH) level during pregnancy is lower than the normal nonpregnancy level.
The new recommendations for TSH levels during pregnancy are the following:
First trimester: less than 2.5 with a range of 0.1-2.5
Second trimester: 0.2-3.0
Third trimester: 0.3-3.0.

During Pregnancy the TSH level may be higher than in a non pregnant state. However in the 3rd trimester a TSH greater than 3.0 would be considered abnormal. During pregnancy as a whole usually an evaluation of thyroid t4 levels are measured if the TSH level is above 2.5 at any time. I would definitely follow up with your ob/gyn
Some labs will have a specific normal range depending on which trimester of pregnancy you are in. If so, refer to that range to see if your result falls into that range. If not, then aTSH below 4 is usually considered normal.
This is a technical question which your obstetrician will answer. The number is meaningless without the unit associated with it. Only your care provider is in a position to advise you on whether you should be concerned in relation to a test he/she has ordered.

That is a normal value for most labs. Nothing to worry about.
That is a normal level and you should have no worries.
Yes this is a normal value
Yes
Yes that is a normal TSH. Your thyroid is working great! Good luck with your new little one!
That depends on whether you are taking thyroid replacement or not. I tend to look at levels of free T3 and free T4 as being more important than TSH since TSH is made by the pituitary and it is not a thyroid hormone - I like my hypothyroid patients to have a TSH between 0.5 and 1.5 in general so yes the TSH might be too high indicating need for more thyroid hormone.
I hope this helps - talk to your doc about checking thyroid levels.

It is recommended that TSH 2.5 and above be treated in pregnancy. There are some studies that have showed an improvement in the IQ points for the baby. But if you are already 36 weeks I do not see a great benefit in starting treatment now.

This is a tough question to answer because I do not have the unit by which they measured this test. In general, there are pregnancy specific values for thyroid function.
A TSH level of 3.17 in the third trimester of pregnancy is on the upper end of the normal range. Depending on whether or not you have any clinical manifestations, I would recommend that you have your free T4 levels checked to see if overt hypothyroidism or subclinical hypothyroidism correlates with your laboratory values as well as your clinical symptoms. Remember that these normal ranges are dependent upon your age as well. If you have any major concerns, I would recommend that you speak with a endocrinologist physician.
I hope this helps.

No, it is not normal, make sure to do free T3 and free T4.
Congratulations on your pregnancy! Yes, your TSH level is normal, the range is 0.5 to 5.

Thank you for your question. Ideally at 9, your TSH levels should be below 3. However, you are just on the borderline above and given that you were within normal limits during your second and third trimester, I would simply follow up with your OBGYN. While I am not an OBGYN, I have seen many times where patients are prescribed T4 in order to raise a possible very, very mild hypothyroidism.
The literature suggests that this may be more detrimental as T4 (Thyroxine) has to be followed up with serially lab testing to ensure the dose is correct.
If you have a healthy baby up to this point, my expert advice would be to have your TSH and Free T4 levels monitored before instituting any treatment.
