Thyrotropin releasing hormone test (TRH)

Patients were studied by dynamic testing (TRH test, T3-suppression test, or a short course of long-acting somatostatin analog, when appropriate), THRB sequencing, and pituitary imaging.

The day before my telephone consultation I sent Prof X an email stating that I was currently taking 75 mcg levothyroxine, I had temporarily stopped my liothyronine (I was asking for a TRH stimulation test to which he responded “we can certainly do that”).

He conducted a TRH test and found a blunted response and diagnosed secondary hypothyrodism and I've been on levo ever since.

Hi, I have had hypothyroidism for a while and am taking L-thyroxine. I had two missed miscarriages before; prior to trying to conceive, I went to my GP to check my thyroid levels and to see if it was safe to conceive. He said yes, but my TSH levels were 4.5. I became pregnant and had my blood drawn at

Hi, All. I was dx with hashimoto 25 years ago. Started on 25 mcg levothyroxin and 20 plus years later my dose was 150. I started SI 2 years ago.

We’ve seen several papers in which it is claimed that it is entirely normal for older people to have higher TSH and lower thyroid hormone levels than younger people. Definition of older (or aged or whatever term they use) varies, but I think we can probably assume most mean at least 65. While this

Hello, I was recently diagnosed Hashimoto's in October, TSH was 144 at the time and antibodies >2000. Currently on a dose of 75mcg with recent TSH at beginning of the month being 3.58.

Hi my name is Tracey and I live in the US. I have been recently dealing with an increase of hypo/autoimmune symptoms and was told to start levothyroxine treatment. I have been on this roller coaster ride for many years starting with a physician telling me I had subclinical hypothyroidism many years ago

I suffered a missed miscarriage in September 24 and no cause was found. On Jan 17th 2025, bloods were done and my TSH was discovered to be 4.8 which I know is linked to miscarriage. On Jan 17th, I was also 4 weeks pregnant. At first, they were reluctant to put me on medication, but then they did and

I had a right hemithyroidectomy in December for a suspicious nodule. I do have a nodule on the left side but apparently this is ok. I was taking 5mg Carbimazole prior and was advised to continue to take it after my surgery as my TSH was <0.008. I have since had my bloods repeated and my TSH is now 8.62

Hi, I was diagnosed with hypothyroid in 2008. My levo meds have gradually gone up to 150 over the years. I also have multiple sclerosis, hiatus hernia and fibromyalgia. My recent tests show normal TSH, high cholesterol, low platelets. The GP that originally diagnosed hypo thyroid did explain to me

Hi All, I was wondering whether supplementing with iron (not mega doses, more 20-30mg daily) increases TSH over time? I feel it’s really slowed me down digestion wise. It started ok but now it’s really noticeable. Anyone have any thoughts? Thanks!
