Thyroid blood test

[France92]

im presently in hospital having lots of tests as ive been poorly for a while they thought cuti but checking everything else out. My main symptoms are sweats low grade fever hair loss lost weight recently uti symptoms. They told me one of my thyroid is bit out but they need to rule out infection first as it can effect your results. Can this happen dont know any results i did have cortisol test this year by gp who said normal but new dr says it needs repeating ? Any advice appreciated

Yes. Acute illness/infection can affect thyroid results, this is why doctors always do two tests a few weeks apart before diagnosing hypothyroidism and wont generally diagnose after just one test.

For full Thyroid evaluation you need TSH, FT4 and FT3 plus both TPO and TG thyroid antibodies tested.

Very important to test vitamin D, folate, ferritin and B12 at least once year minimum

About 90% of primary hypothyroidism is autoimmune thyroid disease, usually diagnosed by high thyroid antibodies 

Autoimmune thyroid disease with goitre is Hashimoto’s

Autoimmune thyroid disease without goitre is Ord’s thyroiditis. 

Both are autoimmune and generally called Hashimoto’s.

Low vitamin levels are extremely common when hypothyroid, especially with autoimmune thyroid disease (Hashimoto’s or Ord’s thyroiditis)

20% of autoimmune thyroid patients never have high thyroid antibodies and ultrasound scan of thyroid can get diagnosis 

In U.K. (and probably French) medics hardly ever refer to autoimmune thyroid disease as Hashimoto’s (or Ord’s thyroiditis)

Recommended on here that all thyroid blood tests early morning, ideally just before 9am

This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)

Please add any results and ranges you have

Cortisol levels often affected by or affect thyroid levels
