This thyroid test looks at T3 and T4 and the ratios of these markers. This can help pick up subclinical hypothyroidism.

The thyroid is the body’s thermostat, controlling body temperature, growth rate and energy use. It regulates the rate at which the body uses food and affects the operation of almost all bodily processes and organs. An under-functioning thyroid gland can result in a condition known as hypothyroidism.
Hypothyroidism is thought to be one of the most under-diagnosed conditions in the world today, affecting children, adolescents and adults.
This disorder can produce many diverse symptoms including fatigue, weight gain, depression and constipation. The thyroid gland can also over-secrete thyroid hormones, resulting in hyperthyroidism with symptoms ranging from weight loss and palpitations to anxiety and diarrhoea.
At Smart Nutrition we pride ourselves in offering the best cost possible for the thyroid T3/T4 test.
