Why would I need a blood test?

Blood tests are one of the most powerful tools for understanding your health. They help detect early signs of illness, monitor ongoing conditions, and provide a clear picture of how your body is functioning. You might need a blood test to:

  • Identify underlying issues like anaemia, thyroid problems, or hormonal imbalances that could be affecting your energy, mood, or weight.
  • Assess risk factors for serious conditions such as heart disease, diabetes, or liver and kidney disorders—even if you’re not showing symptoms.
  • Track vital nutrients like iron, vitamin D, B12, and folate, which are essential for immunity, bone strength, and overall wellbeing.
  • Understand changes in your body due to age, lifestyle, stress, or menstruation.
  • Take control of your health, with clear, science-backed insights you can act on—whether for prevention or peace of mind.

What blood test is used to check thyroid function?

A blood test for thyroid function is used to assess how well the thyroid gland is working by measuring specific hormones in the blood. Rather than relying on a single marker, thyroid blood tests typically look at a combination of hormones to provide a clearer picture of thyroid activity.

These blood tests for thyroid health help identify whether the thyroid may be underactive or overactive and are commonly used when symptoms are present or when monitoring thyroid function over time.

Blood tests for an underactive thyroid

A blood test for underactive thyroid function is commonly used to assess whether the thyroid is producing enough hormones to support normal body processes. In cases of reduced thyroid activity, blood tests often show changes in thyroid-stimulating hormone (TSH) and thyroxine (T4) levels.

Blood tests for an underactive thyroid can help indicate whether further clinical review may be appropriate. Results should always be considered alongside symptoms and medical history, and shared with a healthcare professional if needed.

Blood tests for an overactive thyroid

A blood test for overactive thyroid function is used to assess whether the thyroid is producing higher-than-expected hormone levels. Changes in TSH, along with levels of triiodothyronine (T3) and thyroxine (T4), are commonly reviewed when overactive thyroid activity is suspected.

Blood tests for an overactive thyroid provide valuable information but do not replace clinical assessment. Results are best interpreted in context and can be shared with your GP or specialist for further guidance.
