Please help me interpret my thyroid test results!

Hi, I am 25 male. I was losing hair from both my head and chest. I am the only one who experienced hair loss in my family and therefore I decided to go see a doctor. The doctor prescribed me Thyroid tests and the results came out today:

Serum T4: 98.49 nmol/L (ref 60-120 nmol/L)

TSH: 1.82 μIU/ml (ref .25- 5.0 μIU/ml)

Now I am really confused regarding the test results. Are they normal for a 25 old guy? The doctor didn't seem to bother much about the thyroid level and prescribed some common medicine for hair loss.

Thanks for your help!

  • Welcome to the forum, Akibakib.

    Your thyroid results look quite normal. Ask your doctor to check your iron, zinc and testosterone levels as low levels of any one, or all, of those can cause hair loss.

  • Hi, Thanks a lot for your reply! I checked my testosterone on a different occasion just 8 months back and this came out completely okay!

  • They seem relatively ok however if you experience more symptoms you will need retesting

  • Thanks a lot for your reply :)

  • Any idea if your ferritn levels are good. Low ferrin can cause hair loss.

    You can get it tested at your docs or details of. Private testing are under testing on

  • No idea about the ferritn level. Will go through the links you shared. Thanks :)

  • Personnally, I would say that those tests don't mean much. You have the Total t4 there, which doesn't give much useful infomation, you should have the Free T4 done. And you are missing the most important test - Free T3. That could be low even though the others don't looke too bad.

    I would suggest you get tested again in a couple of months and ask for TSH; FT4; FT3; Anti-TPO and Anti-Tg (antibodies) and also B12; Ferritin; iron; Folate; and VitD. Then you will have a clearer idea of what is going on.
