What is an Endocrinology Test?

The Endocrinology Test is an advanced hormone profile assessing the function of the thyroid gland and reproductive hormone system together. It provides a broad overview of how the endocrine system regulates metabolism, fertility, mood, energy, and sexual health.

This panel includes:

• TSH, Free T4, Free T3
• Anti-Thyroglobulin (Anti-Tg) and Anti-TPO antibodies
• Oestradiol, FSH, LH, Progesterone, Prolactin
• Testosterone, SHBG, Globulin, Free Androgen Index (FAI)

By combining thyroid markers with reproductive and sex hormones, this test helps identify complex hormonal imbalances that may not be detected when testing systems separately.

Why do I need an Endocrinology Test?

Hormones from the thyroid, ovaries, testes, and pituitary gland work together. When one area is out of balance, it often affects others. This test is useful when symptoms are broad, unclear, or involve multiple body systems.

Reasons for testing include:

• Persistent fatigue or low energy
• Weight gain or difficulty losing weight
• Irregular menstrual cycles or fertility issues
• Low libido or sexual dysfunction
• Hair thinning or hair loss
• Anxiety, mood swings, or brain fog
• Menopause or perimenopause symptoms
• Suspected PCOS or androgen imbalance
• Family history of thyroid or endocrine disease
• Unexplained hormonal symptoms

This panel helps uncover root hormonal causes rather than testing individual hormones in isolation.

Benefits of the test

1. Full endocrine system overview

Assesses thyroid and reproductive hormones together.

2. Detects autoimmune thyroid disease

Antibody testing identifies Hashimoto’s and Graves’ disease.

3. Supports fertility investigation

Evaluates ovulation and hormone regulation.

4. Identifies menopause and perimenopause changes

Shows hormonal transition patterns.

5. Detects testosterone imbalance

Useful for both men and women.

6. Helps diagnose PCOS and androgen excess

FAI and testosterone patterns support diagnosis.

7. Explains fatigue and metabolic symptoms

Hormone imbalance often underlies these issues.

8. Supports personalised treatment planning

Provides a complete hormonal picture for targeted care.

Expanded benefit explanation
Endocrine disorders often present with overlapping symptoms. Testing multiple hormone systems together provides a clearer picture and allows more accurate diagnosis and management.

Your results explained

Low levels

Low thyroid or sex hormone levels may indicate gland underactivity or hormonal suppression.

Typical UK ranges:
• TSH: 0.4–4.0 mIU/L
• Free T4: 9–24 pmol/L
• Free T3: 3.1–6.8 pmol/L
• Testosterone:

• Men: ~8–30 nmol/L

• Women: ~0.5–2.6 nmol/L

Low levels may contribute to fatigue, weight gain, fertility issues, and low libido.

Normal levels

Hormones fall within expected ranges for age and sex.

Interpretation:
Endocrine function appears balanced.

High levels

Elevated hormone or antibody levels may indicate endocrine or autoimmune dysfunction.

Possible findings:
• Positive Anti-TPO or Anti-Tg indicating thyroid autoimmunity
• High prolactin affecting fertility
• High testosterone suggesting androgen excess or PCOS
• Low TSH with high thyroid hormones indicating hyperthyroidism

Interpretation:
Further endocrine evaluation may be recommended.
