Diagnosis of Thyroid disease

Diagnosis of Thyroid disease

There are two types of thyroid disease in humans: hypothyroidism disease and hyperthyroidism disease. The main reason for having a serious disease called thyroid in humans is the deficiency or excess of iodine. Hypothyroidism occurs when there is a deficiency of iodine in the body. Hyperthyroidism occurs when there is an excess of iodine in the body. Overuse of dopamine, steroids, or opioid pain relievers (eg, morphine) can also lead to hyperthyroidism. If the patient is taking the steroid, dopamine, or opioid pain relievers (such as morphine), the test may show lower-than-normal levels of TSH.

First of all, the physical examination of the patient is done by the treating doctor, in which the patient’s neck / affected part is closely inspected for thyroid enlargement and the patient is inquired about the disease. After that, the following tests are done to check thyroid function:-

  • Blood test.
  • Imaging test.

Blood Test

Generally, the following three tests are done through a blood test-

  • T.S.H. Test.
  • T3 test.
  • T4 Test.

T.S.H. Test

T.S.H. It is a thyroid-stimulating hormone produced by the pituitary gland. This hormone stimulates the thyroid gland to produce the thyroid hormones T3 and T4. The thyroid gland produces T3 and T4. When for some reason the thyroid gland starts producing thyroid hormones T3 and T4 in less quantity, then the pituitary gland produces T.S.H. Producing hormones stimulate the thyroid gland to produce thyroid hormones T3 and T4. Thus T.S.H. in excess by the pituitary gland. Due to the production of hormones T.S.H. Hormones rise.

Due to the production of thyroid hormones T3 and T4 in small amounts by the thyroid gland, there is a deficiency of thyroid hormones T3 and T4 in the body and hypothyroidism occurs. In hypothyroidism, the label of thyroid hormones T3 and T4 are reduced, and T.S.H. The label increases.

In thyroid disease, the thyroid hormones T3 and T4  are first tested by the doctor. In the test result, when the label of thyroid hormones T3 and T4 is found to be lower or higher than normal, then T.S.H. The test is done.

When the thyroid hormones T3 and T4 are found to be less than normal in the test result, then the condition of hypothyroidism is confirmed. T.S.H in hypothyroidism disease. The label rises.

Thus in hypothyroidism disease, the label of thyroid hormones T3 and T4 is less than normal and T.S.H. Hormone labels are higher than normal.

When the thyroid hormones T3 and T4 are found to be labeled higher than normal in the test result, then hyperthyroidism disease is confirmed. T.S.H in hyperthyroidism disease. The label shrinks.

Thus in hyperthyroidism disease, the label of thyroid hormones T3 and T4 are higher than normal and T.S.H. The label is lower than normal.

T.S.H. in women during pregnancy. maybe higher than the normal label. Overuse of dopamine, steroid, or opioid painkillers (eg, morphine) T.S.H. may be less than the normal label.

For adult person T.S.H. The normal label for is 0.40 mIU/mL to 4.50 mIU/mL. If the blood test shows T.S.H. A label of less than 0.40 mIU/mL indicates hyperthyroidism. If the blood test shows T.S.H. If the label is found to be more than 4.50 mIU/mL, then it is indicated that you have hypothyroidism disease. In such a situation, T3 and T4 hormones are also tested by the doctor through a blood test. All three tests (T.S.H. test, T3 test, and T4 test) are also conducted by the doctor, depending on the condition of the patient.

T3 Test

This test is done by a blood test. If the T3 hormone is found to be higher than normal in the blood test, then hyperthyroidism disease is indicated. If the T3 hormone is found to be less than normal in the blood test, then hypothyroidism disease is indicated.

The normal label for thyroid hormone T3 in adult individuals is 100 ng/dL to 200 ng/dL. If the T3 label in the blood test is found to be less than 100 ng/dL, then hypothyroidism is indicated. If the T3 label in the blood test is found to be more than 200 ng/dL then hyperthyroidism is indicated.

T4 Test

This test is also done by a blood test. If the T4 hormone is found to be higher than normal in the blood test, then hyperthyroidism disease is indicated. If the T4 hormone is found to be less than normal in the blood test then hypothyroidism disease is indicated.

The normal label for thyroid hormone T4 in adults is 5.0 ug/dL to 11.0 ug/dL. If the T4 label in the blood test is found to be less than 5.0 ug/dL then hypothyroidism is indicated. If the T4 label in the blood test is found to be more than 11.0 ug/dL, then hyperthyroidism is indicated.

In the normal condition of thyroid disease, the diagnosis is made only by a blood test.

The risk of developing hypothyroid may be increased if the patient has signs of an autoimmune thyroid disorder. In such a situation, the treating doctor may also conduct the following tests:-

  • Thyroid antibody test.
  • Calcitonin test.
  • Thyroglobulin antibody test (TG antibody test).

Thyroid Antibody Test

Thyroid antibody tests used to diagnose various autoimmune thyroid conditions include thyroglobulin antibody testing (TG antibody test), thyroid receptor antibody test (TSI test), thyroid blocking immunoglobulin test (TBI test), and microsomal antibody testing. Huh.

Calcitonin Test

Calcitonin test is used to detect rare thyroid disorders, medullary thyroid cancer, and C-cell hyperplasia.

Thyroglobulin Antibody Test (T.G. antibody test)

Thyroglobulin antibody test (TG antibody test) is used to diagnose thyroid inflammation (thyroidism). This test is also used by doctors to monitor thyroid cancer treatment.

Imaging tests (thyroid scan)

In this test, the enlarged size of the thyroid gland is detected through an ultrasound. This ultrasound takes about half an hour.

A biopsy test may also be done by the doctor if there is a possibility of a lump in the thyroid gland or cancer.
