About the examination 

Screening type: Thyroid hormone stimulating Test

Sample: Serum

Unit of measurement: IU/L

It is a test that measures the level of thyroid hormone in the blood. The thyroid gland is a small butterfly-shaped gland located near the throat. The thyroid gland creates hormones that regulate the way your body uses energy. These hormones also play an important role in regulating weight, body temperature, muscle strength, and mood. TSH is formed in a gland in the brain called the pituitary gland. When the body’s thyroid levels are low, the pituitary gland makes more TSH. When thyroid levels are high, the pituitary gland secretes less TSH. Very high or very low TSH levels can indicate that the thyroid gland is not functioning properly.

This test is used to diagnose

This test is used to detect the effectiveness of thyroid function.

The reasons for the examination

You need to take this test if you have symptoms of a lot of thyroid hormone in your blood, a condition called hyperthyroidism, or symptoms of hypothyroidism, a condition called hypothyroidism.

Symptoms of hyperthyroidism include:

  • Concern.
  • Weight loss.
  • Trembling hands.
  • Increased heart rate.
  • Bulge throughout the body.
  • Bulging eyes.
  • Sleep problems.

Symptoms of hypothyroidism include:

  • Weight gain.
  • Fatigue and general weakness.
  • Hair loss.
  • Inability to withstand cold temperatures.
  • Irregular menstrual cycle.
  • Constipation.

How to conduct the examination

During the test, a laboratory specialist takes a blood sample from one of the veins in your arm using a small needle. After the needle is inserted into the vein, a small amount of blood will be collected in the test tube for later analysis in the laboratory using special devices. It should be remembered that this test takes no more than five minutes, during which you will only feel a small tingling when the needle is inserted into and removed from the vein.

How the disease prepares for testing

This analysis does not require any special equipment. If your doctor has asked for further tests on the withdrawal blood sample, you may need to be healthy and drinking for several hours before the analysis. Your doctor will tell you what special instructions you may need to follow before you perform the analysis.

The risks of screening

There is very little risk of this analysis, as you will feel a tingling, a slight pain or mild bruising where the blood sample is removed that disappears during days and there is no risk.


Interpretation of the results of the examination

High levels of thyroid-guided hormone mean that your thyroid does not produce enough thyroid hormones, a condition called hypothyroidism.

The TSH test does not explain why TSH levels are high or low. If the test results are abnormal, your doctor may ask for additional tests to determine the cause of the thyroid problem.

These tests may include:

  • Thyroid hormone Test T3.
  • Thyroid hormone Test T4.
  • Tests to diagnose Graves’ disease: an autoimmune disease that causes hyperthyroidism.
  • Tests to diagnose hashimoitis: an autoimmune disease that causes hypothyroidism.

Changes in the thyroid gland can occur during pregnancy. These changes are usually not important, but some women may develop thyroid disease during pregnancy.  Hyperthyroidism occurs in one in every 500 pregnancies, while hypothyroidism occurs in approximately one in 250 pregnancies. 

Hyperthyroidism, often hypothyroidism, may remain after pregnancy. If you have a thyroid disease during pregnancy, your doctor will monitor your condition after birth. If you have a history of thyroid disease, be sure to talk to your doctor if you are pregnant or considering pregnancy. It should be noted that the normal proportion of thyroid hormones during pregnancy is different from normal rates in the absence of a pregnancy.
