How Do You Check For Thyroid

Why It Is Done

How to Do a Self Thyroid Exam

Thyroid hormone tests are done to:

  • Find out what is causing an abnormal thyroid-stimulating hormone test. This is the most common reason for thyroid hormone tests.
  • Check how well treatment of thyroid disease is working. The total thyroxine , free thyroxine , and free thyroxine index values are often used to keep track of treatment for hyperthyroidism.
  • Screen newborns to find out if the thyroid gland function is normal. A condition called congenital hypothyroidism can prevent normal growth and development and cause other severe problems, such as intellectual disability, if it is not treated soon after birth.

Why You May Need A Thyroid Test

Women of all ages are more likely than men to have low thyroid hormone levels. However, many of their symptoms are attributed to other conditions or written off as a consequence of aging.

A blood test for levels of TSH is the most sensitive test for determining whether you have hypothyroidism. Most laboratories use 0.45 5.00 mIU/L as a normal reference range for TSH. People with TSH between 5.00 and 9.99 mIU/L often have no symptoms , but some do. Another test called T4 will be done if your TSH is in this range. A low level of T4 usually means you will benefit from thyroid hormone replacement.

Many people with hypothyroidism or subclinical hypothyroidism aren’t aware anything is wrong because they haven’t been tested. The U.S. Preventive Services Task Force doesn’t recommend thyroid screening because it hasn’t found sufficient evidence that testing thyroid hormone levels in large groups of people without symptoms is cost-effective. Dr. Garber agrees, and suggests a different approachtesting asymptomatic people who are most likely to develop thyroid disease and benefit from treatment.

Treating subclinical hypothyroidism with synthetic thyroid hormone may reduce the risk of developing more serious problems like cardiovascular disease. They note that low thyroid hormone can cause a high cholesterol level and treatment with thyroid hormone may make statin therapy unnecessary.

Who Is This Test For

People who may benefit from having a thyroid function test include:

Individuals who are concerned that they may have a thyroid problem and those who wish to monitor a previously diagnosed condition.

Early signs and symptoms of thyroid dysfunction may often be very non-specific. The common symptoms hypothyroidism may include:

  • Unexplained weight gain
  • Bulging, dry, puffy or irritated eyes
  • Difficulty sleeping

What will the result show?

Our thyroid test will report your levels for all three hormones . You will receive a personalised interpretation of what the results mean and what you should do about them. This may be as simple as all is well, to a recommendation to see your GP if we detect an abnormality.

In hypothyroidism, the thyroid gland does not produce sufficient thyroxine, so the T4 and T3 levels are low.

This causes an increase in TSH to try and stimulate the thyroid to produce more thyroxine.

In hyperthyroidism the thyroid gland produces too much thyroxine, so the T4 levels are high. This causes a decrease in TSH to try and stop the thyroid producing more thyroxine.

I use MMH to keep an eye on my thyroid levels and as its an NHS lab, my GP and endocrinologist can use the results to monitor me. I was grateful for having the option of home testing last year, when I was unable to get to my surgery due to ill health. Very quick service and I like the graphs showing my health journey.

Pattern #: Depressed Thyroid Binding Globulin Leading To Hypothyroidism

This is a pattern associated with High Testosterone. High Testosterone reduces thyroid binding hormone levels making more free hormones available.

The thyroid and pituitary are again working properly, but this time there is too much T4 converted to T3 . High levels of testosterone is the cause which also has the added effect of decreasing the amount of thyroid binding globulin .

The high levels of T3 in conjunction with low TBG causes cells to become resistant to T3. They close the doors and do not allow anymore T3 into the cells. TSH levels will be normal even though the patient is showing signs of hypothyroidism.

This pattern is similar to insulin resistance. In fact, patients with thyroid over conversion often also present with insulin resistance and polycystic ovary syndrome which is also caused by increased testosterone levels. Managing blood sugar is extremely important. Since there is already too much T3, prescription thyroid medication will not help in this pattern.

Lab Evaluation: Normal or Low TSH, Normal or Low T4 & T3 Levels, Normal or High Free T4 & High Free T3 Levels

Common Causes: Testosterone replacement or insulin resistance.

What Tests Do Doctors Use If I Have A Thyroid Nodule

How to test your Thyroid at home

If your health care professional finds a nodule or lump in your neck during a physical exam or on thyroid imaging tests, you may have a fine needle aspiration biopsy to see if the lump is cancerous or noncancerous.

For this test, you will lie on an exam table and slightly bend your neck backward. A technician will clean your neck with an antiseptic and may use medicine to numb the area. An endocrinologist who treats people with endocrine gland problems like thyroid disease, or a specially trained radiologist, will place a needle through the skin and use ultrasound to guide the needle to the nodule. Small samples of tissue from the nodule will be sent to a lab for testing. This procedure usually takes less than 30 minutes. Your health care professional will talk with you about the test result when it is available.

Is There Anything Else I Need To Know About A Tsh Test

TSH levels may be high or low even when your thyroid gland is healthy. Serious illnesses not related to your thyroid may cause lower TSH levels for a short time. And TSH levels may be higher in people over age 80, even though they dont have any thyroid problems.

Pregnancy also affects TSH levels. They are often a little low during the first three months. But sometimes, thyroid disease develops during pregnancy. If you develop thyroid disease during pregnancy, your provider will monitor your condition through your pregnancy and after your baby is born. Thats because hyperthyroidism, and less often, hypothyroidism, can continue after you give birth. If you have a history of thyroid disease, be sure to talk with your provider if you are pregnant or are thinking of becoming pregnant.

Newborn babies are routinely screened with a TSH test to see if they were born with hypothyroidism .

Normal And Abnormal Tsh Ranges

  • 0.4 mU/L to 4.0 mU/L is considered the , and people who have a normally functioning thyroid gland usually fall within this range.

  • If TSH measures more than 4.0 mU/L, a second test is performed to verify the results. TSH of more than 4.0/mU/L with a low T4 level indicates hypothyroidism.

  • If your TSH is more than 4.0 mU/L and your T4 level is normal, this may prompt your physician to test your serum anti-thyroid peroxidase antibodies. When these antibodies are present, it may indicate an autoimmune thyroid disorder, which is a risk factor for developing hypothyroidism. If you have these antibodies, your doctor will most likely perform a TSH test at least once per year.

An easy way to remember how the thyroid worksthink about supply and demand. As the T4 level falls, the TSH rises. As the T4 level rises, the TSH falls. However, not everyone with hypothyroidism has elevated levels of TSH.

If your pituitary gland is not working properly, it may not send out normal TSH amountsand if this is the casethe thyroid may be healthy. However, if the amount of TSH is off, the thyroid wont make the right amount of T4. This is rare and is known as secondary or central hypothyroidism.

What Is Your Thyroid

The thyroid gland is a small, butterfly-shaped organ located in the lower front of the neck. It’s just above your clavicle and below your larynx .

Growths on the thyroid can be nodules and goiters or thyroid cancer. Lumps in the neck can be caused by thyroid disease or other conditions such as:

  • An infectious abscess
  • A traumatic injury

However, you should know that a neck check is not considered the most accurate or reliable way to identify thyroid disease. You can have serious thyroid disease and have a completely normal neck check.

On the other hand, finding a major growth on your thyroid is likely not a serious problem often, it’s a sign of an easily treatable condition, such as an iodine deficiency.

Your Lymph Nodes Are Swollen
