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. Choose a quick 15-minute clinic test in Neath or 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.

In-Clinic 15-Minute Thyroid Test vs Home Kits

• In-clinic TSH test (Neath): a quick blood sample taken by our clinical team. Your sample is analysed using our diagnostics system or partner lab, with results and explanation provided by our pharmacist.
• Home thyroid test kit (UK): take a finger-prick sample at home and post it to a UK-accredited laboratory for a comprehensive thyroid report.

Browse home thyroid and hormone test kits or book your in-clinic TSH test.

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.
