Thyroid test at home in Dubai
Many routine checks report TSH alone. The screen runs a full thyroid panel, TSH, FT3 and FT4, so you can see the signal and the response together.
What the test measures
TSH. Thyroid stimulating hormone, the signal from the pituitary gland asking the thyroid to work. It rises when the thyroid is underactive and falls when it is overactive.
Free T4 (FT4). The main hormone the thyroid produces, measured in the free form the body can use.
Free T3 (FT3). The more active thyroid hormone, mostly made from T4 in the body's tissues.
Who should test
TSH is a useful screening number, but it is a signal, not the hormone itself. Free T4 and free T3 show what the gland is actually producing. Reading all three together makes it easier to tell a clear pattern from a borderline one, such as a TSH near the top of the range with free hormones that are low or normal.
The thyroid sets the pace of your metabolism. An underactive thyroid is linked with tiredness, feeling cold, weight gain, dry skin, constipation and low mood. An overactive one is linked with a racing heart, anxiety, weight loss, heat intolerance and poor sleep. Thyroid problems are more common in women and often run in families.
- Tiredness or sluggishness that does not lift
- Unexplained weight gain or loss
- Feeling cold, or unusually hot and shaky
- Hair thinning or dry skin
- Changes to your periods
- A family history of thyroid problems
How to prepare
- Stop biotin supplements, including hair and nail formulas, for at least two days before the draw. Biotin can distort thyroid results.
- If you take thyroid medication, ask your own doctor whether to take it before or after the draw, and tell your consultant the dose.
- Follow the fasting instructions for the full screen. A morning draw keeps results comparable over time.
Reading your results
If TSH is high
A high TSH with low free T4 is the common pattern of an underactive thyroid. A high TSH with normal free hormones is often called subclinical and is usually rechecked. Your consultant will explain what your pattern means and when to see your own doctor.
If TSH is low
A low TSH with high free T4 or free T3 can suggest an overactive thyroid. Illness, some medicines and biotin can also shift results, so they are read in context.
Reference ranges
Thyroid ranges differ between labs and change in pregnancy. A result is read against the lab's own range and your symptoms, not a single number from the internet.
Reference ranges differ between labs, and a single result is a snapshot. Your consultant reads every value against your history and the rest of the screen, not in isolation.
How the home test works
This test is part of Baseline’s full blood screen: 122 parameters across ten systems from one draw, for AED 850, with results in 48 hours. It is not sold as a single test, because the result means more next to everything else.
- Nurse comes to you. A licensed phlebotomist visits your home or office, 7 days a week, anywhere in the UAE.
- Accredited lab. Samples are processed by a CAP-accredited laboratory (College of American Pathologists), also accredited to ISO 15189, against clinical reference ranges.
- Reviewed with you. Results land in your account in Baseline format, and your consultant walks you through them on video, never a PDF dumped in your inbox.
Ranges are the lab’s own. Your consultant goes through what they mean with you.
Your results arrive in the Baseline app, every marker against the lab’s own range, checked by your consultant before you see them. The values above are an example.
Questions
- Why test FT3 and FT4 as well as TSH?
- TSH shows how hard the body is asking the thyroid to work. Free T4 and free T3 show what the thyroid is actually producing. Together they give a clearer picture than TSH alone.
- Does biotin affect thyroid tests?
- Yes. Biotin, common in hair and nail supplements, can interfere with the lab method and make results look falsely high or low. Stop it for at least two days before the draw.
- My TSH is near the top of the range. Is that a problem?
- Not necessarily. It is worth reading alongside free T4, free T3 and your symptoms, and often rechecking after a few months.
- Can I book a thyroid test on its own?
- No. The thyroid panel is part of the Hormone Profile in the full home screen, measured from the same single draw.
