Broda Barnes described a simple and accurate test in 1976 to diagnose an underactive or overactive thyroid. This is because these abnormalities are often missed when performing a blood test, with all the associated consequences.

How is the test going?
1. Measure your body temperature every morning 10 minutes before getting up and write it down
2. Repeat the test for a few days

What does the temperature say?
- Between 36.6 and 36.8 ºC is normal temperature
- Significantly lower than 36.6 ºC may indicate an underactive thyroid
- Significantly higher than 36.8 ºC may indicate an overactive thyroid

Note! Menstruating women should take the test on day 2 or 3 of the menstrual cycle.
