Thyroid (TSH) Blood Test – Private Thyroid Testing in Neath

Our thyroid blood test measures TSH (Thyroid Stimulating Hormone), the key marker used to screen for underactive and overactive thyroid conditions.
We offer a quick 15-minute clinic test in Neath with results typically available in around 3–15 minutes using our onsite analyser, as well as a home thyroid test kit with UK laboratory analysis.

What Does the TSH Thyroid Test Measure?

TSH (Thyroid Stimulating Hormone) is produced by the pituitary gland and controls how much thyroid hormone (T4 and T3) your thyroid makes. When thyroid levels are low, TSH usually rises; when thyroid levels are high, TSH usually falls.

A TSH test is the standard first step for checking whether your thyroid is functioning normally.

Why Have a Private Thyroid Blood Test?

A thyroid problem can cause a wide range of symptoms that are easily mistaken for stress, ageing or low mood. Testing may be helpful if you experience:

• Unexplained tiredness or low energy.
• Weight gain or weight loss without trying.
• Feeling unusually cold or hot compared to others.
• Low mood, anxiety or “brain fog”.
• Dry skin, hair loss or brittle nails.
• Palpitations, fast heartbeat or tremor.

Our private thyroid test offers a convenient option alongside NHS care, giving you results and guidance quickly.

Your 15-Minute Thyroid Test – How It Works

Our in-clinic thyroid test is a fast and accurate venous blood test performed by our trained phlebotomist using our own diagnostic equipment onsite. Here’s what to expect:

1. Quick pre-test check: We confirm your symptoms, medical history and any thyroid medication.
2. Venous blood draw: A small sample of blood is taken from your arm by our trained phlebotomist. This is usually very quick and well tolerated.
3. Immediate analysis onsite: Your sample is placed straight into our analyser, giving fast and reliable TSH results in around 3–15 minutes.
4. Results explained: Your pharmacist talks you through what your TSH level means, whether it suggests hypo- or hyperthyroidism, and if any further tests (such as Free T4 or antibodies) are recommended.
5. Clear next steps: You leave with a written or verbal plan, plus advice on when to repeat the test or when to contact your GP.

If you prefer to test at home, we also offer a convenient Thyroid (TSH) Home Test Kit with UK-accredited lab analysis.

Understanding Your Thyroid Results

TSH results are interpreted in context, but in general:

• High TSH can indicate an underactive thyroid (hypothyroidism).
• Low TSH can suggest an overactive thyroid (hyperthyroidism).
• Normal TSH usually means thyroid function is within the expected range.

If your result is outside the normal range, we’ll advise you to speak to your GP for confirmatory tests (such as FT4, FT3 or antibodies) and long-term management.
