Brief Answer:
autoimmune hypothyroidism is likely.

Detailed Answer:
Welcome to health care magic.

Your daughters report is showing raised TSH (49.69) and raised serum anti TPO ANTIBODY (54.7) test. We consider up to 40 as a normal TPO antibody depending upon the laboratory variations,so it would be helpful to confirm it ,if you will provide me reference ranges of your LAB's thyroid fucntion tests.

This is likely indicative of hypothyroidism means deficiency of thyroid hormones in blood which could be autoimmune here.

Since antibodies are raised, cause is autoimmune hypothyroidism.

Treatment should be continued to her in the form of thyronorm (Eltroxin 75 mcg) which is correct here.

I would recommend to repeat thyroid function test every 3 months and adjust dose of thyronorm (Eltroxin) accordingly.

In addition,I would like to tell that thyroid tablet (Eltroxin) should be taken on empty stomach to get maximum absorption from the stomach as food might interfere with its absorption.

Ideally it is taken after 2 hours of having meal or before 45 minutes of meal.
Means it is best not to eat anything for at least 1 hour after taking Eltroxin.

Hope this detailed answer will be helpful.

Brief Answer:

Detailed Answer:
Welcome again,

Yes,we consider up to 40 as clinically normal and beyond this value would be suggestive of some autoimmune problem which is hypothyroidism in your daughter's case.

With regular thyroid tablets (eltroxin) and follow-up at your treating doctor with adjusting the dose of eltroxin as per TSH values,there will not be any problem to your daughter in future.

Rest of all precautions as I explained earlier while taking this tablet.

Hope this helps.
