I have Hashlmotos and Thyroid Eye Disease. Recent tests for my eyes included thyroid antibody tests. A letter I received from the hospital gave these results and I should like to know what they mean.
TSH receptor antibodies 0.3
Thyroid peroxidase antibodies >600
Anti - thyroglobulin antibodies 929
TSH 0.27 and FT4 21.1
I take 200 micrograms of levothyroxine daily.
Do you have the reference intervals (ranges) for those tests?
They do vary between labs so without them we are guessing - which doesn't do anyone any favours.
Thank you for your reply.No ranges were given although the tests were done in a city teaching hospital.
If you are able, I suggest you contact the lab which did the tests - or find their website - and look them up. (Some labs have really good websites but some are terrible.)
Hello Parsnip and welcome to the forum :
We need the ranges to say conclusively what these results mean but from experience I guessing you are negative for Graves Disease with TSH Receptor reading -
but positive with both over range TPO - thyroid peroxidase - and TgAB anti - thyroglobulin - and dealing with Hashimoto's thyroid auto immune disease.
Your T4 looks as though it could be close to being over range - if not already over range - but we need a Free T3 reading alongside this Free T4 reading to advise as to how well this dose of T4 is working for you.
What symptoms, if any, are you dealing with ?
You might like to talk with the Thyroid Eye Disease Charitable Trust tedct.org.uk as they can signpost you to specialist eye units throughout the country, generally attached to the large teaching hospitals, where an endo and ophthalmologist work together to find the best treatment option for both your thyroid and eyes.
If taking any eye drops or ointments please ensure all are Preservative Free - even those prescribed by the NHS.

Thank you for your reply.I have been taking levothyroxine for 11 years and only ever seeing my gp in this time.
These blood tests were done in a well known teaching hospital. The consultant I saw is a specialist in thyroid eye disease.
I was referred there as during a routine eyetest Specsavers detected a problem. They passed me to New Medica who then referred me to an eye clinic in a large teaching hospital.
The eye clinic then asked their endocrine department to examine me as I had only been diagnosed and treated by my gp.
A scan showed my thyroid was no longer working due to hashimotos.
I shall contact the hospital and request the ranges as you suggest.
Just testing TSH and Ft4 is inadequate
What vitamin supplements are you taking
When were vitamin levels last tested
Do you always get same brand levothyroxine at each prescription
For full Thyroid evaluation you need TSH, FT4 and FT3 tested
Very important to test vitamin D, folate, ferritin and B12 at least once year minimum
Low vitamin levels are extremely common when hypothyroid, especially with autoimmune thyroid disease
Lower vitamin levels more common as we get older
For good conversion of Ft4 (levothyroxine) to Ft3 (active hormone) we must maintain GOOD vitamin levels
Recommended that all thyroid blood tests early morning, ideally just before 9am, only drink water between waking and test and last dose levothyroxine 24 hours before test
This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)
Private tests are available as NHS currently rarely tests Ft3 or all relevant vitamins
