Concierge thyroid testing · London
Private thyroid function panel in London, interpreted by an endocrinologist.
The standard blood panel for suspected thyroid dysfunction — with proper context, correct timing, and an endocrinologist for the interpretation when it matters.
Why patients choose us
- 01
Endocrinologist interpretation
A consultant endocrinologist reads the pattern — not just whether a number sits inside a range.

Right markers, right timing
Morning sample, biotin held, dose timing checked. Small details that change the answer.
- 03
Accredited labs only
UKAS-accredited pathology with age- and trimester-adjusted reference ranges.

The problem
A thyroid result out of context isn’t an answer.
Reference ranges shift with age and pregnancy. Biotin skews the assay. Levothyroxine timing changes the number. Getting the pattern right is the part that matters — that’s what we do.
-
A borderline TSH?
We help decide whether to repeat, add antibodies, or watch — before anyone starts treatment.
-
Planning a pregnancy?
TSH targets are tighter pre-conception. We interpret against the right range.
-
On levothyroxine?
We time the sample properly, review the dose, and coordinate with your GP.

- 01
Before
You tell us what’s going on
A short, confidential form. Symptoms, medication, prior thyroid results if you have them.
- 02
Before
We recommend the right panel
Within one working day: TSH alone, TSH + free T4, full panel, or panel + antibodies — whichever answers the question.
- 03
Before
We book the appointment
A morning slot in clinic, or a home phlebotomy visit. We confirm biotin and levothyroxine timing.
- 04
On the day
The blood draw
A few minutes with an experienced phlebotomist. Take your levothyroxine dose AFTER the sample.
- 05
On the day
Off to the lab
Your sample goes to a UKAS-accredited pathology laboratory the same day.
- 06
After
Endocrinologist review
A consultant endocrinologist interprets the pattern, not just the numbers.
- 07
After
We explain them
We talk you through what the result means and arrange any next step — repeat, antibodies, ultrasound, or dose change.
Typical end-to-end: 2–5 days. Urgent cases: same day.
What it shows
When a thyroid panel is the right test.
The situations we see most — plus the one red flag that means A&E, not a private test.
-
Suspected hypothyroidism
Fatigue, weight gain, cold intolerance, low mood — the classic underactive picture.
-
Suspected hyperthyroidism
Palpitations, weight loss, tremor, heat intolerance, anxiety — the overactive picture.
-
Postpartum thyroid changes
Silent or symptomatic swings in the year after delivery — a common and treatable pattern.
-
Subclinical (raised TSH) picture
A mildly raised TSH with normal T4 — when to repeat, when to treat, when to add antibodies.
-
Pre-pregnancy planning
TSH targets are tighter before and during pregnancy. Worth checking before conception.
-
Thyroid nodule follow-up
Function alongside a known nodule, coordinated with ultrasound or scintigraphy.
-
Medication monitoring
Levothyroxine dose titration, amiodarone or lithium monitoring — done at the right interval.
-
Red flag: thyroid storm
Fever, severe palpitations, agitation — call 999. This page is for stable, planned testing.
Popular panels
The thyroid panels we arrange most.
What each option is actually for.
-
TSH only
The single most informative marker — the right first test for most people.
-
TSH + free T4
Adds free T4 for a fuller picture where TSH is borderline or symptoms are marked.
-
Full panel (TSH, fT4, fT3)
The standard workup for suspected hyperthyroidism or unclear patterns.
-
Thyroid antibodies (TPO, TG)
To pattern-diagnose autoimmune thyroid disease (Hashimoto’s, Graves’).
-
Full panel + endocrinology review
Panel plus a 60-minute consultation with a consultant endocrinologist.
-
Pre-conception thyroid check
Timed and interpreted against pre-pregnancy TSH targets.
-
Postpartum thyroid check
For symptomatic swings in the year after delivery.
-
Amiodarone-induced thyroid check
Structured monitoring for patients on amiodarone or lithium.
Our vetted London network
A small panel of labs and endocrinologists, we picked them.
Partners across central, north, west and south London, plus home phlebotomy. Not listed publicly — introductions are made privately, once we understand your case.
Selection criteria
How we choose every laboratory and endocrinologist in our network.
-
UKAS-accredited pathology laboratories
-
Consultant endocrinologists for interpretation and review
-
Age-adjusted and trimester-specific reference ranges
-
Onward pathway to thyroid ultrasound or scintigraphy where indicated
Preparation and practicalities
Small details that change the answer.
A thyroid panel is simple to run — but timing, biotin and dose can change the number. We tell you exactly what to do.
-
Fasting
Best done fasting where practical, but not essential for a thyroid panel alone.
-
Time of day
A morning sample is preferred — TSH follows a diurnal rhythm and is highest overnight.
-
Biotin supplements
Avoid biotin (vitamin B7) for at least 48 hours before the test — it can distort assay results.
-
Levothyroxine timing
Take your levothyroxine dose AFTER the blood test on the day of the sample.
-
Pregnancy
Pregnancy has trimester-specific reference ranges — we interpret against the correct one.
-
Postpartum shifts
Postpartum thyroid shifts are common in the year after delivery and often self-resolve.
-
One-off abnormal result
A single mildly abnormal result usually deserves a repeat before any decision.
-
Antibodies help
TPO and TG antibodies help pattern-diagnose autoimmune thyroid disease.
-
Share prior results
Always share previous thyroid results — trend matters more than a single reading.
Reading your report
A thyroid report looks intimidating. It isn’t.
However many markers are run, the report follows the same four parts.
A quiet reminder
A reference range is a guide, not a verdict — pattern and trend matter.
If you would like us to talk you through it before your follow-up, just ask.
- 01 Header
Indication and medications
Why the panel was requested, and the medications and supplements that might influence it.
- 02 Technique
Which markers were measured
The exact assays run — TSH, free T4, free T3, antibodies — and the laboratory that ran them.
- 03 Findings
Each marker against its range
Each result alongside the age- or trimester-appropriate reference range, with anything outside flagged.
- 04 Impression
Read this first
Normal, subclinical, overt — and what to do next: repeat, add antibodies, adjust dose, or refer for ultrasound.
Recognised by major UK insurers
Routine screening is often self-funded; where testing is medically indicated we confirm cover with your insurer.
Frequently asked
Everything we get asked about thyroid panels.
Quick answers on markers, fasting, biotin, pregnancy, cost and results.
-
What does a thyroid function panel measure?
The core panel measures TSH (the pituitary signal), free T4 and free T3 (the circulating thyroid hormones). Antibody tests (TPO, TG) can be added to pattern-diagnose autoimmune thyroid disease.
-
Do I need to fast before a thyroid blood test?
Fasting is best where practical but not essential for a thyroid panel alone. A morning sample matters more than fasting.
-
Can biotin supplements affect thyroid results?
Yes. Biotin (vitamin B7) can distort thyroid assay results. Stop biotin at least 48 hours before the test.
-
Are thyroid reference ranges different in pregnancy?
Yes. Pregnancy has trimester-specific ranges, particularly for TSH. We interpret your result against the correct range for your stage.
-
What is postpartum thyroiditis?
A common shift in thyroid function in the year after delivery, sometimes hyperthyroid then hypothyroid then back to normal. It is often self-limiting but always worth checking.
-
How much does a private thyroid test cost in London?
TSH alone is typically £45–£90, TSH + free T4 £65–£130, a full panel £120–£240, and a full panel with a consultant endocrinologist review £250–£500.
-
Do I need a referral?
No — most private thyroid panels accept self-referral. For interpretation and any onward step (ultrasound, scintigraphy, medication), an endocrinologist review is worthwhile.
-
How quickly do I get results?
TSH and free T4 usually come back within 24 hours, a full panel in 24–48 hours, and antibodies in 3–5 days.
-
When do thyroid antibodies matter?
When TSH is borderline, when hypothyroidism is suspected in a young woman, in pregnancy or pre-pregnancy planning, and when a firm autoimmune diagnosis will change treatment or monitoring.
-
When should I see a GP urgently?
Fever, severe palpitations and agitation with a known overactive thyroid can suggest thyroid storm — call 999. New chest pain, breathlessness or severe symptoms warrant urgent assessment.
