(T3, T4, TSH)
(FT3, FT4, TSH)
Thyroid, in throat, is a small gland which produces two: hormones thyroxine (abbreviated as T4) and tri-iodothyronine (T3). It is located below the Adam’s apple that is in the lower part of the neck. Its shape is similar to a butterfly. It plays a vital role in metabolism, brain development, body temperature regulation, menstrual cycles, weight, etc. Iodine is used by the thyroid gland to produce hormones. Improper functioning or excessive secretion of hormone by thyroid gland can lead to neck thickening, weight loss, high cholesterol, lethargy, etc. Thus, proper functioning of this gland can be measured by undergoing thyroid test in Gurgaon.
When hypothalamus produces TRH (thyroptin-releasing hormone), TSH is produced. It is TRH that triggers the pituitary gland which then releases TSH. TSH is responsible for the production of T3 and T4, both of which help in metabolism of our body. For brain’s normal growth, both T4 and T3 are required.
For this test, blood samples are generally collected. This panel includes three tests, namely total T4, total T3 and thyroid stimulating hormone (TSH). It can be easily done at home in Gurgaon by just booking an appointment with Next Door Lab. The two major disorders of thyroid are hypothyroidism and hyperthyroidism. These can be diagnosed easily by undergoing thyroid test. Thyroid function blood test will help in evaluating if the thyroid hormone production is normal, underactive or overactive.
Free T3 (FT3), free T4 (FT4) and thyroid antibodies are some other tests performed. Radioactive iodine uptake (RAIU) is a non-blood test performed when thyroid gland uptakes iodine from blood more actively under the condition called hyperthyroidism. Normal values of TSH vary for adults, children and newborns. It should range from 0.4 to 1.2 mU/L for adults, from 0.7 to 6.4 mU/L for children, and from 1 to 39 mU/L for newborns. Thyroid scans, thyroid needle biopsy, and thyroid ultrasound are done under following conditions:
TSH is produced in a tiny organ known as the pituitary gland. In hypothyroidism, TSH level increases, while decreases in hyperthyroidism. Symptoms of hyperthyroidism include:
Symptoms of hypothyroidism include:
During thyroid disorder, regular check-up is must. High TSH results indicate that the thyroid gland is underactive and the person is suffering from hypothyroidism. The most common cause of primary thyroid is Hashimoto’s thyroiditis. While a low TSH result indicates the overactive pituitary gland and is suffering from hyperthyroidism. The most common cause of hyperthyroidism is Grave’s disease (goiter). Factors that affect TSH test result include extreme stress and acute illness. Normal FT3 and FT4, and high TSH indicate mild hypothyroidism. Low FT3 and FT4, and high TSH indicate hypothyroidism. Normal FT3 and FT4, and low TSH indicate mild hyperthyroidism. High/normal FT3 and FT4, and low TSH indicate hyperthyroidism. if all three tests (FT3, FT4 and TSH) are low, this indicates secondary hypothyroidism. If FT3 and FT4 are high with normal TSH, this means there is thyroid hormone resistance syndrome, which is a mutation in which thyroid hormone function decreases in the thyroid hormone receptor. Thyroglobulin is another blood test for thyroid function that helps in detecting thyroid cancer. Only thyroid cells produce this protein.
Before going for next test, the American Thyroid Association suggests waiting for 6--8 weeks. The US Preventive Services Task Force is unable to justify fully in favor for or against routine thyroid screening in asymptomatic adults. On the other hand, the American Association of Clinical Endocrinologists and the American Thyroid Association suggest routine screening for hypothyroidism for those aged 60 and have released the guidelines for the same effectively in 2012.
Thyroid results may vary and following factors might affect the condition:
Medications may also affect thyroid gland function test like taking aspirin and undergoing thyroid hormone replacement therapy.
Follow your health practitioner and the medications he/she provide. Although there is no particular cure, taking pills is the only way to keep things working. It is a life-long treatment which requires taking the pill everyday in the morning on an empty stomach. The doctor decides the dose and adjusts accordingly until an optimal dose is reached. This requires regular monitoring and that too throughout life. Before deciding to end with your medication, do consult your doctor because doing so might revert the same condition from where you started the treatment.
Treating thyroid by nutritious diet proves vital. Increase the consumption of fruits and vegetables in your routine. This will help in keeping you healthy. But taking non-vegetarian food is what will add to increase your thyroid problem. Consuming beans lessens the chances to suffer from this disorder, as they are rich in proteins and vitamins. This will help in easy production of thyroid hormone. Iodine, the most important source required by the thyroid, should be consumed in proper amount. But patients with high blood pressure cut-down the amount which will lead to this problem. Therefore, consume alternative foods like sea food, yoghurt milk, sea vegetables and eggs.
