Understanding your thyroid results
Reference ranges used at Bangkok international hospitals (may vary slightly by lab):
- ▸TSH normal range: 0.4–4.0 mIU/L — below 0.4 suggests hyperthyroidism; above 4.0 suggests hypothyroidism
- ▸Free T4 normal: 0.8–1.8 ng/dL — low T4 with high TSH = primary hypothyroidism
- ▸Free T3 normal: 2.3–4.2 pg/mL — elevated T3 with low TSH = hyperthyroidism
- ▸Anti-TPO antibodies: <35 IU/mL is normal — elevated = Hashimoto's thyroiditis (autoimmune hypothyroidism)
- ▸Anti-TG antibodies: <40 IU/mL is normal — elevated with nodules = further monitoring needed
- ▸Thyroid nodule found on ultrasound: most are benign (95%+); size >1cm or suspicious features trigger FNA biopsy recommendation
- ▸Bangkok doctors will provide a clear English-language explanation of results; ask for the reference ranges on your result sheet
Who should get a thyroid test in Bangkok?
Groups for whom thyroid screening is particularly relevant:
- ▸Women aged 30–60: thyroid disorders are 5–8× more common in women; hypothyroidism is very common in perimenopausal women
- ▸Expats in Bangkok: iodized salt use varies; some expats from countries with less iodine fortification have higher risk
- ▸Anyone with symptoms: unexplained fatigue, weight changes, hair loss, feeling cold/hot all the time, heart palpitations
- ▸After COVID-19: post-COVID thyroid dysfunction (subacute thyroiditis) has been documented; worth checking 3–6 months after infection
- ▸Family history of thyroid disease: Hashimoto's and Graves' disease run in families — screen from age 25–30 if first-degree relatives affected
- ▸Anyone on lithium, amiodarone, or interferon: these medications can cause thyroid dysfunction
