Thyroid stimulating hormone or TSH as it is more popularly known as; this is a blood test that assesses this hormone. The thyroid is a tiny gland shaped like a butterfly located near the throat. Our bodies need the energy to function and the thyroid gland makes hormones that regulate the way your body uses the energy. It plays a vital role in maintaining an ideal weight, temperature, mood, and muscle strength. The hormone is produced in a gland situated in a part of the brain called the pituitary. When the levels of this hormone are low, the pituitary gland makes more TSH, and when the levels are high, less TSH is produced by the pituitary gland. The level of this hormone is an indication of how healthy the thyroid is.

The electrocardiogram or ECG test.

In this test, a moving piece of paper or a screen is used to record the activity and rhythm of the heart, the dips and peaks on the screen or paper can be interpreted by your physician to check for any unusual or abnormal activity.
