Hormone and Thyroid Panel Plus blood test in Chiswick

What the test measures

Hormones work as a network, so symptoms such as tiredness, irregular periods, weight change, low mood or reduced libido can have more than one cause. This panel looks at several hormone systems together. The thyroid section includes TSH, free T4 and free T3, plus thyroid peroxidase and thyroglobulin antibodies, which can show autoimmune thyroid disease.

Reproductive hormones include FSH, LH, oestradiol, progesterone, prolactin, testosterone, sex hormone binding globulin and the free androgen index. Anti-Müllerian hormone (AMH) estimates the number of eggs remaining in the ovaries. Cortisol and DHEA-S reflect adrenal activity, and insulin and HbA1c show how the body manages blood sugar, which is closely linked with conditions such as polycystic ovary syndrome.

The price includes your sample taken at our Chiswick clinic, analysis at the Randox accredited laboratory, a review of your result with an Omnia practitioner, and a GP feedback report on request.

Who it is for

• You have irregular or absent periods and want to understand why.
• You are thinking about fertility and would like an AMH result alongside other hormones.
• You have symptoms that could be thyroid related, such as tiredness, weight change or feeling cold.
• You have acne, excess hair growth or other signs that may relate to polycystic ovary syndrome.

Understanding your result

Your report shows the laboratory reference range for each marker, many of which vary with age and cycle stage. For example, a raised TSH with low free T4 suggests an underactive thyroid, while raised testosterone and LH with higher insulin can fit a polycystic ovary syndrome pattern. A lower AMH suggests fewer remaining eggs, but it does not predict whether you can conceive naturally.

High prolactin can be caused by stress, some medicines or a pituitary issue. A result outside the range is a prompt for discussion, not a diagnosis, and your practitioner will help you decide on next steps with your GP if needed.

Preparing for your test

Book a morning appointment, ideally before 10am, as cortisol and testosterone are highest early in the day. If you have periods, the best time for FSH, LH and oestradiol is day 2 to 5 of your cycle, while progesterone is most informative about seven days before your next period, and we will help you choose the timing. Fasting is not essential, though a light breakfast helps the insulin result. Stop high-dose biotin for 48 hours, and tell us about hormonal contraception or HRT, which affect several results.

Questions

How much is the Hormone and Thyroid Panel Plus in Chiswick?

The Hormone and Thyroid Panel Plus costs £249 at our Chiswick clinic. This includes your blood sample, analysis of all 18 markers at the Randox accredited laboratory, a practitioner review and a GP feedback report on request.

When in my cycle should I take this test?

Day 2 to 5 is usually best for FSH, LH and oestradiol, and AMH can be tested at any time. We will help you choose based on what you most want to learn.

Can I take it while on the pill?

You can, but hormonal contraception changes several results, especially FSH, LH and oestradiol. Let us know so your practitioner can interpret them correctly.

Does AMH tell me whether I can get pregnant?

No. AMH estimates the number of eggs, not their quality or your chance of natural conception. It is most useful when planning fertility treatment or timing.
