Blood Test for Hormone Levels

Thyroid Testing
This is done easily as a blood test requisition by your family doctor. However, be aware that requesting general blood work often does not include thyroid levels. The thyroid must be requested and tested separately.  It is a separate box to be “ticked” on the form.  Be sure to ask your doctor if the requisition includes a Thyroid test.

The common test is for the thyroid is TSH (Thyroid Stimulating Hormone).  The TSH results will be measured against a scale from 0.5 – 5.0.  Results within this range are considered normal.  The score can be a bit confusing, as a low thyroid is a score of over 5.0 and an overactive, or high, thyroid is below 0.5.  A less common test for thyroid is called a Free T4.  This measures another background aspect of thyroid function and can be very helpful for your doctor in getting a full picture of what your thyroid is doing.  Free T4 testing is expensive and must be made by special request by your doctor.

Cortisol testing

Cortisol is also easily tested through a requisition from your family doctor. Like the thyroid, it must be noted separately on the requisition, otherwise it will not be included.

Usually this test involves going to the lab for your bloodwork twice during the day of the test.  Once, to measure your morning cortisol level (usually before 9 a.m.) and again in the afternoon to measure your p.m. cortisol level (usually around 4:00 p.m.)  Specific times are required for this, so ask your doctor which times you need to attend.

Sex Hormone Testing
(progesterone, estrogen, testosterone)

These blood tests are not commonly requested by a doctor unless there is a suspicion of a woman entering menopause. Having these levels tested, even when not in menopause or long after menopause has occurred, can be important in managing your optimal health. If your doctor is reluctant to request these tests, go to a Naturopath and request saliva testing.
