TSH Blood Test

Thyroid Stimulating Hormone (TSH)

A Thyroid stimulating hormone (TSH) blood test is commonly ordered when an individual is suspected of having thyroid troubles. Thyroid stimulating hormone is made in the pituitary gland and stimulates the production of other hormones that help the body with metabolism. As one might suspect the metabolism is very important in the controlling of weight, mood and even growth of the individual.  The TSH blood test is often ordered with or following the a Thyroid Profile.

Why The Test Is Given

The TSH blood testing may be done when a person is experiencing symptoms of weight loss, weight gain, irregular menstrual cycles, tiredness, feelings of extreme hot or cold, rapid heart rate along with many others. The level of TSH monitored with the blood testing should be in the range of .5 to 5.0. Levels detailed by the blood tests that are abnormally higher or lower can signify medical conditions that should be treated or further diagnosed. An underactive thyroid gland is oftentimes referred to as hypothyroidism and causes weight gain, dry skin, constipation, tiredness and abnormal menstrual cycles. An overactive thyroid is known as hyperthyroidism and can lead to weight loss, abnormal menstrual cycles, increased heart rate and diarrhea.

The TSH blood test can detail the hormones levels in the blood stream and allow individuals to undergo more testing to determine the cause of the thyroids abnormal functioning. There are medications, as well as other treatments for overactive and underactive thyroids making the prognosis good for poor results detailed with the blood test. TSH blood tests are also important for children as the levels are imperative to their development, for both physical and cognitive growth.
