Why is this test important? This test delivers an enhanced thyroid profile, because it screens for the level of free T4 and T3 hormones in the bloodstream. This is an important distinction, since the level of free T4 hormone illustrates how much is immediately available for uptake and use by cells, and measure of free T3 hormone in the body is considered a more accurate view of hormonal balance than a total T3 reading. In addition, this test also measures the level of thyroid-stimulating hormone (TSH) produced by the pituitary gland. This test result will indicate if your body is producing too much—or too little—of this critical hormone, which regulates T4 and T3 output.
What does the test include? The HealthCheck USA Thyroid Panel: T4 Free, T3 Free with TSH is a test that checks:
Because this test includes a TSH screening, remember that medications like corticosteroids, aspirin and lithium can interfere with those results. Also, if you've had a recent X-ray that used iodine dye—or other radioactive tests—ask your doctor when you can take an accurate TSH test. Pregnant women in their first trimester should also ask their doctor about the proper time to get a TSH test. The full panel of results will be analyzed by an accredited medical laboratory, and can be accessed on the HealthCheckUSA Web site within four business days after a blood test.
Who should be tested? Strongly consider testing if you have a family history of thyroid problems, or have been diagnosed with chronic fatigue syndrome, pituitary or endocrine disorders. In addition, strongly consider testing if you are a woman in or near menopause, or are pregnant or just had a baby (since proper T3 and T4 levels are essential to brain development in the early years of a child's life). You should also consider testing if you are experiencing symptoms of hypothyroidism (unusual weight gain, lethargy, dry skin, a constant feeling of cold, or constipation) or hyperthyroidism (sudden weight loss, increased heart rate, recurring warm or sweaty feeling, or diarrhea).
