This was tested in people. That is the most reliable kind of research we share.
This was a look back at patient records at one hospital, not a treatment.
The short version
A hormone test may help doctors spot a thyroid problem linked to a pituitary tumor.
What was studied. Doctors looked back at the records of 105 people who had a hormone test called the TRH test. The groups were 25 people with no tumor, 13 people with a tumor and low thyroid hormone, and 67 people with a tumor and normal thyroid hormone.
What they found. The 13 people with low thyroid hormone had a weaker response to the test. Their responses were also more often slow or drawn out. When doctors used two or more cut-off values together, false alarms dropped to 4%. Some of the 67 people with normal thyroid hormone also had a positive result.
What this means, and what it doesn't
What it could mean: If you have a pituitary tumor or one nearby, this test may help your doctor check how your thyroid is being controlled. It may point to a problem that regular blood levels do not show.
What it doesn't mean: This is not a new treatment, and it is not a cure. Doctors only looked back at old records at one hospital. They did not set up a new study in advance to test this. More work is needed before this changes everyday care.
