QuantiFERON-TB Gold Blood Test

* This is not a home test kit. You will need to visit a local lab for testing.

Use

The QuantiFERON-TB Gold Test is a Tuberculosis (TB) test used to detect the presence of the deadly Tuberculosis bacterium in your body through a one-time blood collection.

How does it work?

The process is simple. The QuantiFERON-TB blood test employs cutting-edge diagnostic technology to detect the antibodies that your body would produce in reaction to Tuberculosis (TB). In technical terms, QFT employs special blood collection tubes that allow viable blood lymphocytes to be exposed to highly specific Tuberculosis antigens and test controls coated on the tubes’ inner surface. To help in the detection of tuberculosis infection, antigen exposure induces a measurable immunological response.

What is the procedure of getting tested?

Step 1: Buy the test online and generate a lab order. This lab order doesn’t require a doctor’s approval, depending on the state that you’re in.

Step 2: Find a local lab that is at a feasible distance and carry the order with you.

Step 3: Present the order at the lab and get your blood drawn.

Step 4: Receive an accurate test result, sent directly and confidentially to your Personalabs account (usually within 48 hours).

Keep in mind that this is not an at-home testing kit. It is a walk-in lab test.

How efficient is the current testing and medication?

QuantiFERON-TB Gold is an IGRA (Interferon-Gamma Release Assays) that has been clinically evaluated and verified a vast number of times. Over 30 million of these tests have been sold in over 125 countries, with over 7 million units sold in 2015 alone. QFT is one of the only Tuberculosis infection blood tests that includes:

• Single-visit testing

• The most reliable and repeatable TB infection findings

• Over 1200 clinical and scientific research to back it up

• Easy and objective ELISA technology

This means that you can truly trust it.

Recommended for:

It is recommended for anyone who has either knowingly been in contact with someone who has active/latent tuberculosis or developed any of the mentioned symptoms.

The following are the typical signs of active tuberculosis in the lungs (pulmonary tuberculosis):

  • Coughing for a long period (2-3 weeks), sometimes with bloody spit
  • Weakness
  • Chills and fever
  • Unanticipated weight loss
  • Sweats at night
  • Pain in the chest
  • Appetite loss

Symptoms of tuberculosis infection outside of the lungs (extrapulmonary illness) differ depending on the infection location. It can induce a small number of symptoms or a large variety, such as:

  • Paralysis and back pain (spinal TB)
  • Joint ache
  • Joint ache anemia, causing weakness (TB in the bone marrow)
  • Pain in the abdomen
  • Pain in the abdomen
  • Pain affecting the reproductive system or urinary tract, which might lead to infertility
  • TB in the brain and/or central nervous system, causing altered mental state, headache, and coma
  • Shortness of breath and fever (pericardium or military TB, which occurs when M. tuberculosis infects multiple organs)

About the condition

What is tuberculosis, briefly?

Mycobacterium tuberculosis causes tuberculosis, an infectious illness. Tuberculosis is a disease that predominantly infects the lungs (pulmonary TB). Other areas of the body, however, may get infected as a result of the initial infection or, quite often, as a result of a subsequent widespread infection.

When a person with tuberculosis coughs, sneezes or spits, respiratory droplets carrying Tuberculosis bacterium are released into the surroundings, and others stand the risk of inhaling them. A typical sneeze from a patient with latent pulmonary tuberculosis can include up to 4,000 Tuberculosis bacterium droplets. A human can become sick if only 10 of those germs are breathed in by someone close.

Who is commonly at risk?

  • Other illnesses can enhance the chance of acquiring active tuberculosis once infected, such as insulin-dependent diabetes, end-stage renal disease, previous gastrectomy, or HIV infection.
  • Remicade (infliximab), Humira (adalimumab), or Enbrel (adalimumab) are examples of drugs that inhibit tumor necrosis factor-alpha (etanercept). This can also make someone vulnerable to TB.
  • People who have been in contact with patients who have previously tested positive for either latent or active TB of any kind
  • Elderly people and people with a compromised immune system (like someone suffering from an auto-immune disease)
  • Patients who are starting therapy for TNF
  • Immigrants
  • Patients who are on dialysis
  • Individuals that are in a group setting
  • Patients undergoing organ or hematologic transplantation
  • Users of illegal drugs.

About methods of testing

There are two methods of testing for TB, a skin test and a blood test.

1.) Tuberculin Skin Test (TST) (also known as a Mantoux test or PPD (purified protein derivative))

A substance called tuberculin is injected into the skin of the forearm for the Tuberculin Skin Test. A medical expert examines the injection site after two or three days for a lump or elevated region that might suggest TB bacterium infection.

2.) TB Blood test or Interferon-Gamma Release Assays (IGRAs)

TB germs can be detected by a blood test. By analyzing a person’s blood in a laboratory, the test determines how well their immune system reacts to tuberculosis bacterium.

Which one is better?

The blood test is much better because one, it is more accurate, two, it is easier (single-visit test) and three, it is pretty cost-effective.

What do the results look like?

If you get a “positive” Tuberculosis blood test, it implies you have TB bacteria in your body. The majority of patients who test positive for tuberculosis have a latent infection. Your doctor will check on you and do a chest x-ray to be certain. Other tests may be required to determine if you have a latent TB infection or active TB illness.

How to prepare for the test?

On the day of your Tuberculosis blood test, have a nutritious breakfast and drink lots of water. Stay hydrated in the days leading up to your visit as well. This will help the blood test go much more smoothly.
