There is considerable evidence that the current tests for
the diagnosis of hypothyroidism (low thyroid function) are insensitive and
somewhat lacking in accuracy.
Broda Barnes, M.D., an Endocrinologist and thyroid specialist,
in his book, "Hypothyroidism, an Unsuspected Illness," explains
his thoughts and theories about this matter. He proposes that the
most sensitive and accurate test for determining low thyroid function
is to check the most basic function of the thyroid, i.e., its ability
to regulate the metabolic furnace -- creating heat and controlling
temperature. Dr. Barnes states that recording the basal body temperature
daily for ten days is the most simple and accurate means of doing
this. For accuracy he insists that the client/patient be totally relaxed
with no movement during the axillary temperature testing.
INSTRUCTIONS: Do the following for 10 consecutive days.
If you skip a day, you must begin again.
1. Use an oral thermometer which has been shaken down the
night before and put on your bedside stand.
2. Put the thermometer in your armpit (for ten minutes)
and record below a temperature each morning for ten days. Do this
before you get out of bed. This means do it while lying prone and
before you have urinated, had any beverage or food or done anything
either mentally or physically. Dr. Barnes suggests using the axillary
(armpit) temperature rather than the mouth because many people have
low grade unsuspected sinus infections which generate heat only in
that area, thereby, falsely raising the oral temperature.
3. For women, additional consideration is needed during ovulation
which elevates temperature somewhat. Because of this, women who menstruate
should start the recording on the second or third day of their cycle. For
men and women who are menopausal, it makes no difference which day you begin.
This temperature recording data will be correlated by
your Clinical Nutritionist along with your thyroid hormone level through
serum blood analysis, and your thyroid history questionnaires. This
is a common and easily reversed dysfunction. Dr. Barnes estimates
that approximately 40% of the adult population have this problem and
it can be associated with hypoglycemia, allergies, psoriasis, acne,
undiagnosed skin problems, hypertension, obesity, depression and many
other ailments. If you have any unusual response or if there is anything

KEY: 97.8F OR 36.5C or below is considered abnormal.
