A TSH blood test measures thyroid-stimulating hormone, a signal from your pituitary gland that tells your thyroid how much hormone to make. It is ordered to check for an underactive or overactive thyroid and to monitor thyroid treatment.
What it measures
- TSH (thyroid-stimulating hormone) — The main marker; high or low levels can suggest thyroid problems.
- Free T4 (thyroxine) — Sometimes added to see how much active thyroid hormone is available.
- Free T3 (triiodothyronine) — Less often checked; helps assess thyroid function in some cases.
- Thyroid antibodies — May be tested if autoimmune thyroid disease is suspected.
Who it is for
A healthcare provider typically orders a TSH test if you have symptoms like fatigue, weight changes, or a fast or slow heartbeat, or to monitor thyroid medication.
Preparation
No fasting is usually required. Tell your provider about any thyroid medicines or supplements you take, as timing may matter.
Results and what they mean
