Thyroid function baseline profile
Thyroid function baseline profile
Why would I take this test?
The thyroid is a small butterfly-shaped gland in the neck, just in front of the windpipe (trachea). One of its main functions is to produce hormones that help regulate the body's metabolism (the process that turns food into energy).
If your thyroid is underactive or overactive, it affects your energy levels, weight, mood, temperature sensitivity, heart rate, sleep, and skin and hair condition.
This profile checks the function of your thyroid gland so you and your GP can confidently work on a thyroid-related diagnosis and treatment plan.
How a test is done?
Our phlebotomist will tie a rubber band to your upper arm to make the veins more visible. They will swab to clean the arm, then a sterile needle attached to a tube is gently inserted into the vein and the blood is drawn into a vial (or vials if more than one test has been requested). Only one needle is used regardless of the number of tests or vials requested. The needle is removed, a plaster applied, and it’s done. You might get a small bruise around the needle mark.
Please wear loose clothing (for easy access to your arm) and let us know a preferred arm.
You can continue to take regular medication but check with your doctor whether any of your medications may affect test results.
It's easier to draw blood when:
you are hydrated – please drink some water, especially in hot weather and for morning blood draws
you are warm – please keep warm before the test
Fasting is not required
A non-fasting test means:
you can eat and drink as normal before the test
it’s advised not to drink alcohol before the test
you can continue to take regular medication but check with your doctor whether any of your medications may affect test results
