Why is this test important? This test delivers a baseline profile that can help evaluate and diagnose potential thyroid gland disorders. In addition to measuring the total level of T4 hormone in your body, which accounts for nearly 90 percent of overall thyroid hormone content, this test also estimates how much binding protein is available for T3 hormones to effectively function. 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 HealthCheckUSA Thyroid Panel: T4 Total, T3 Uptake with TSH is a baseline screening 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).
