Before jumping to today topic about the Advanced Thyroid Test, understand the thyroid and its function.

What is Thyroid?

The gland is a small organ in our body that is located in the front of the neck. It is wrapped around the windpipe. It is shaped like a bow tie that extends around the side of your throat. That gland is thyroid or thyroid is a gland. 

This gland makes thyroid hormones that help or control many vital functions of your body. The hormones travel in your blood to all your body. When these thyroid hormones don’t work properly, they can impact your body.  

What does Thyroid Do?

The thyroid plays an important role in your body. It releases and controls the thyroid hormones that control your metabolism with specific hormones like T4(thyroxine), T3(triiodothyronine). These hormones tell the body cells how much energy to use. 

There is a supreme leader called the pituitary gland located in the center of the skull below your brain. This pituitary gland monitors and controls the amount of thyroid hormone in your blood. This pituitary gland is called the thyroid-stimulating hormone (TSH). 

Thyroid Disease

A condition called hyperthyroidism occurs when your thyroid makes too much thyroid hormone, then your body uses energy quickly. When this condition occurs you feel tired, fast heartbeat, weight loss and feel nervous. 

There is another condition called hypothyroidism that occurs when your thyroid makes too few thyroid hormones in your body. It makes you feel tired, weight gain and feel cold. 

Now let’s understand the Advanced Thyroid Test

What is the Advanced Thyroid Test?

We know that the thyroid gland makes thyroid hormones like T3 and T4. The thyroid gland consistently releases these hormones in our body. So the blood test determines the number of hormones produced by the gland. 

A blood test finds out the amount of TSH, T3, and T4 in our blood. Some thyroid hormones are bound for certain proteins in the blood and only unbound thyroid hormones are active and effective. These free thyroid hormones are called FT3 and FT4(F stands for free).

Advanced Thyroid Test

If the number of thyroid hormones T3 and T4 is high or low in our blood, there is an imbalance. These tests find out the levels of substance and what is causing the imbalance. 

Thyroid Stimulating Hormone (TSH)

If the level of this hormone is high means hypothyroidism. And if TSH levels in the blood are low maybe a sign of hyperthyroidism. 

Free Triiodothyronine (FT3) and Free Thyroxine (FT4)

High levels of these free hormones in the body may be a sign of overactive thyroid, and low levels could be a sign of underactive thyroid. 


Now we know about advanced thyroid test and why it is important. If there are any symptoms of thyroid visit the doctor.

What is Tuberculosis?

Tuberculosis (TB),  is a highly infectious disease that primarily affects the lungs, caused by the bacteria Mycobacterium tuberculosis. The bacteria spread through the air from person to person, when an infected individual coughs or sneezes out the bacteria, spreading it through the air to be breathed in by others and mainly attacks the lungs, but it can affect other areas of the body such as the brain, kidney, or spine.

What Are the Symptoms of TB?

TB disease usually grows slowly, and it may take some weeks before you notice you’re unwell. Your symptoms might not begin until months or even years after you were initially affected. The infection may go through three stages:

Primary TB Infection

This is when the bacteria first arrive in your body.  Primary infection, occurs in people without specific immunity, In general, normal children and young adults who have not previously been exposed to Mycobacterium tuberculosis. 

In most people, this causes no symptoms but others may experience fever or pulmonary symptoms. 

Latent TB Infection

This TB bacteria can live in the body without making you sick. This is called latent TB infection. They do not have any symptoms but can possibly develop active TB disease.

Active Disease

Active TB disease is contagious. That means it can be reached from one person to another. It is most often spread through the air.


  • Cough that lasts two weeks or more
  • Pain in the chest        
  • Coughing up blood or thick mucous
  • Night sweats
  • Feeling weak or tired
  • Weight loss
  • Not wanting to eat
  • Fever
  • Swollen neck gland(s)

How to Prevent TB?

Prevention is the key to stop the transmission of TB. Tuberculosis is a preventable disease if detected and treated early. It consists of early diagnosis and treatment of active TB to stop contagious.

If you have been in contact with someone who has active tuberculosis or thinks you may have, consult your health care provider. If you plan to travel to countries with high rates of TB, visit a health care provider or travel health care clinic 6 weeks before you leave. If you believe you are at risk of getting tuberculosis, ask about getting a skin test:

  • before your trip
  • after your trip

How Is Tuberculosis Diagnosed?

The most regularly used diagnostic tool for TB is a simple skin test, though blood tests are becoming more commonplace.

Blood tests

Blood is used to confirm or rule out latent or active tuberculosis. These tests measure your immune system’s reaction to tuberculosis bacteria.

Imaging tests

If your skin test comes positive, your doctor is likely to order a chest X-ray or a CT scan. This may show white spots in your lungs where your immune system has separate TB bacteria, or it may disclose changes in your lungs caused by active TB. CT scans provide more-detailed images than do X-rays.

Sputum tests

If a chest X-ray shows signs of tuberculosis, your doctor may take samples of your sputum — the mucus that comes up when you cough. The samples are tested for tuberculosis bacteria.

Treatment of TB

If you have TB, but do not have active TB disease you should get preventive therapy. The most usual protective therapy is a daily dose of the antibiotic isoniazid (INH) taken as a single daily pill for six to nine months. You are not infectious if you have latent TB.

In case of active TB disease, you will probably be treated with a combination of antibacterial medications for a period of six to 12 months. 

There are drugs currently approved by the U.S. Food and Drug Administration (FDA) for treating tuberculosis. Of the approved drugs, the first-line anti-TB agents that form the core of treatment regimens are:

  • isoniazid (INH)
  • rifampin (RIF)
  • ethambutol (EMB)
  • pyrazinamide (PZA)


A healthy immune system is very crucial nowadays. It is the best defense against TB.  It is very important to finish the medicine, and take the drugs exactly as prescribed. Know you know what is tuberculosis and how we can prevent it.
