Thyroid Blood Test

 Get a Thyroid Blood Test to monitor your metabolic health, energy levels, and hormonal balance. Our three Profiles offer a comprehensive insight.

1. Basic Thyroid Function Profile

Core Screening for Metabolic Balance

The Basic Thyroid Blood Test is the essential first step in understanding how your body is managing its energy. Think of your thyroid as your body’s “thermostat”—it regulates everything from how fast your heart beats to how quickly you burn calories.

Is this Thyroid Blood test right for me?

This profile is designed as an entry-level check or for ongoing management. It is the ideal choice if you:

  • Need a Routine Check: You have a known thyroid condition and need to monitor your levels regularly.
  • Are Noticing Early Changes: You’ve started feeling unexplained fatigue, “brain fog,” or a sudden change in your weight.
  • Feel Sensitive to Temperature: You feel unusually cold or struggle with the heat.
  • Want a Baseline: You want a clear, clinical snapshot of your metabolic health without the deeper autoimmune or nutrient markers.

What we look at (and why it matters):

To give you an accurate “engine check,” our Thyroid Blood Test measures the three most critical markers in your bloodstream:

  • TSH (Thyroid Stimulating Hormone): This is the “messenger” from your brain. It tells us if your body is asking for more energy or trying to slow down.
  • FT4 (Thyroxine): The main storage hormone produced by your thyroid. It acts as the “fuel tank” for your metabolism.
  • FT3 (Free Triiodothyronine): This is the active form of the hormone that your cells use. It is the “spark plug” that drives your energy levels and heart rate.

Our Approach: At Windsor Mews Clinic, we believe that clear answers are the foundation of great health. We provide the clinical accuracy you need to establish your baseline, helping you move from “feeling off” to finding facts.

The Investigative Checklist:

  • Core Thyroid: TSH, FT4, FT3
  • Antibodies: Thyroid Peroxidase (TPO), Thyroglobulin (TGAB)
  • Inflammation: CRP (High Sensitivity)
  • Vitamins: Vitamin D, Vitamin B12, Folate
  • Iron Stores: Ferritin

2. Advanced Thyroid Health Profile

Deep Dive into Autoimmunity & Nutrient Support

If your basic thyroid blood test levels are “normal” but you still don’t feel right, the Advanced Thyroid Health Profile is the next logical step. This profile goes beneath the surface to identify why your thyroid might be struggling, focusing on your immune system and the “fuel” your body needs to produce hormones.

Is this test right for me?

This profile is our most popular choice for those who want a more “investigative” look at their health. It is specifically designed for:

  • The “Invisible” Symptom: You have typical thyroid symptoms (fatigue, weight gain, thinning hair) but have been told your TSH is “fine.”
  • Autoimmune Concerns: You want to screen for conditions such as Hashimoto’s or Graves’ Disease, where the body’s immune system attacks the thyroid.
  • Inflammation Tracking: You feel “puffy” or achy and want to see if systemic inflammation is impacting your energy.
  • Nutrient Optimisation: You want to ensure your body has the right levels of vitamins and minerals to use the hormones it produces.

What we look at in a Thyroid Blood Test - Why it matters:

In addition to the core thyroid markers, we include three critical diagnostic layers:

  • Thyroid Antibody Panel (TPO & TGAB): These markers tell us if your immune system is mistakenly attacking your thyroid gland. This is often the “missing piece” in chronic fatigue cases.
  • Inflammation Marker (CRP): High-sensitivity CRP helps us identify if silent inflammation is “clogging” your metabolic pathways.
  • The Essential Nutrient Panel: We measure Vitamin D, B12, Folate, and Ferritin (Iron). These are the raw materials your thyroid needs. Without enough “fuel” in the tank, even a healthy thyroid cannot function at 100%.

Our Goal: At Windsor Mews Clinic, we recognise that “normal” isn’t always “optimal.” We specialise in uncovering the hidden factors, from nutrient gaps to immune responses, that stand between you and feeling your absolute best.

3. Advanced Thyroid Plus Hormones Profile

The "Full Picture" for Total Hormone Harmony

Thyroid health doesn’t exist in a vacuum; it works in tandem with your reproductive hormones. If one is off-balance, the others often follow. This is our most comprehensive assessment, designed to map exactly how thyroid function affects your overall hormonal health.

Is this test right for me?

This profile is the best choice if you are struggling with “complex” symptoms that are hard to trace to a single root cause. It is specifically designed for those experiencing:

  • Persistent physical changes: Such as unexplained hair loss or constant low energy.
  • Cycle & Fertility concerns: Including irregular periods or difficulty conceiving.
  • Mood & Outlook: Managing “brain fog,” mood swings, or a sudden drop in libido.
  • Life Transitions: Helping to determine if symptoms are thyroid-related or linked to PCOS, Menopause, or Andropause.

What we look at (and why it matters):

We go beyond the basics to look at three key areas of your internal health:

  • Complete Thyroid & Antibody Check: We check not just how much hormone you are making, but if your immune system is mistakenly attacking your thyroid.
  • Sex Hormone Mapping: By measuring Oestradiol, Testosterone, and Prolactin, we can see how your reproductive health is impacting your drive and vitality.
  • The “Brain-to-Body” Connection: We test markers like FSH and LH to see if your brain is sending the right signals to your body, and SHBG to ensure those hormones are reaching the cells that need them.

Our Vision: At Windsor Mews Clinic, we treat the body as a connected system, not a collection of parts. Our goal is to provide the high-resolution data necessary to restore your natural rhythm and achieve total hormonal harmony.
