Private Thyroid Profile 1 (FT4/TSH) London

A thyroid function blood test evaluates how well your thyroid gland produces and regulates hormones that control metabolism, energy levels, heart rate, body temperature, and overall wellbeing. When thyroid hormones are out of balance, even slightly, they can affect multiple systems in the body.

A thyroid blood test may be recommended if you are experiencing symptoms that suggest hormonal imbalance or if you require routine monitoring. Common reasons include:

• Persistent fatigue or low energy

• Unexplained weight gain or weight loss

• Sensitivity to cold or heat

• Hair thinning or hair loss

• Changes in heart rate or palpitations

• Low mood, anxiety, or brain fog

• Irregular menstrual cycles

• Ongoing laboratory monitoring of thyroid-related health

This blood test to test thyroid function is also frequently used after medication changes or as part of a broader health assessment.
