What does .24 tsh level mean ?

Question

I currently take 200mcg levothyroxine.

Blood test says .24 tsh... point 24 ?

Doctor says that’s fine, is it over or under ? Thanks

Answer 1

A TSH reading above 4.0 mIU/L is considered high (elevated). This indicates hypothyroid state.
Test result post treatment shows 0.24 which is normal.
The doctor has put you on treatment with 200mcg levothyroxine and this has caused your TSH level to revert back to normal because your hypothyroid state has been treated. So ... "You're fine."

Answer 2

First you should talk to your doctor about this.

You medicine is for an underactive thyroid per webMD
https://www.webmd.com/drugs/2/drug-1433/...

thyroid-stimulating hormone = tsh
see this article
https://www.everydayhealth.com/hs/health...

Per the article
==== excerpts
“TSH levels go in the opposite direction of your thyroid hormone,” Dr. Doria-Medina explains. “If you’re making too little thyroid hormone, your TSH will go up. If you’re making too much thyroid hormone, your TSH will go down.”

"Some variation is normal because your pituitary gland sends out TSH in pulses, not a steady stream. Also, the time of day you're tested can make a difference. TSH levels are likely to be higher at night and lower during the day".

"A normal range for TSH in most laboratories is 0.4 milliunits per liter (mU/L) to 4.0 mU/L"
=== end excerpts.
This article indicates that under the normal range indicate you are in the range now of possibly too much thyroid hormone. But I would trust your Doctor, but talk about it in a phone call or next time you have
an appointment asking about any of your concerns.
.

So you are under the normal low range, but your Doctor probably knows things
like what is good level while taking your medicine.
