Basal Body Temperature
Advocated and extensively researched by Broda Barnes, M.D., this technique has been shown to be a more sensitive indicator of hypothyroidism than blood testing. The basal body temperature (BBT) has continued to be a controversial technique, as has the form of therapy, dessicated thyroid, advocated by Barnes and others. The tests are done for a five day period with first waking in the morning. In women, this should be done 3-4 days after the menstrual period has begun. At this time thyroid hormone is reaching its highest point and cellular metabolism is optimal. Therefore, under ideal conditions, the basal body temperature gives an indication of
what is occurring during optimal thyroid output rather than from a random blood draw, even if done at the same time. Further, it gives a better indication of what is occurring at the cellular level by measuring the body's metabolic response.

According to Barnes, a temperature of greater than 98.0 degrees F (36,7¤ C) denotes a normally functioning thyroid. Temperature from 97.6 to 98.0 degrees F are marginal while temperatures less than 97.6 degrees F (36,5 C) indicate hypothyroidism. Some practitioners consider any temperature under 98 degrees F to be hypothyroid under these conditions. As previously mentioned, the test must be conducted under optimal conditions in order to be an effective indicator of the thyroid state.

Som vel betyr at blodprøver kan være fine, men hvis ikke morgentempen er normal er ikke stoffskiftet normalt heller.

Såvidt jeg kan forstå nevnes også forskjellige måleunøyaktigheter ved de forskjellige testmetoder som brukes.
