This test is used to find out whether the individual is infected with tuberculosis TB or not by using a sample of lymph node tissue obtained by biopsy.
What is Tuberculosis?
Tuberculosis TB is a bacterial infection caused by Mycobacterium tuberculosis MTB. Generally, TB affects the lungs and sometimes it can also affect other organs and parts of the body. MTB is airborne and can spread through the air from one person to another. Individuals who are suffering from TB may experience symptoms such as cough which lasts more than 2-3 weeks, cough with blood, chest pain, difficulty in breathing, weight loss, fever, night sweats, etc.
What is lymph node biopsy?
The process of collecting a small tissue sample of the lymph node is called lymph node biopsy. The lymph nodes are small oval-shaped organs of the immune system which are located in various regions of the body and are commonly noted in armpits, neck and groin area. The lymph nodes will be swollen in response to an infection present in the body and which can be detected through biopsy.
What is a Biopsy?
The biopsy is the process of collecting a small sample of tissue from various parts of the body. The sample for biopsy may include skin, the lining of the stomach, kidneys, liver, a fragment of bone or bone marrow, etc. This procedure is more like a minor surgery and an individual may recover within a day to one week based on the procedure. In this type of procedure, your doctor administers a small dose of local anesthetic at the site of surgery and collects a small sample of tissue from the suspected organ and is sent to the laboratory for further analysis.
Why this test Is performed?
This test is performed to check the presence of tuberculosis DNA in the tissue of the lymph node of an individual. The doctor may ask you to undergo this test if you are suffering from symptoms such as long-lasting cough, chest pain, difficulty in breathing, weight loss, fever, etc.
If you are on treatment for tuberculosis, then the doctor may ask you to perform this test to evaluate and to check the effectiveness of the treatment and to check whether the bacterium is resistant to TB drugs such as rifampicin. Mostly, this test is done along with other tests to confirm the diagnosis
Some medications may change the test results and hence you are advised to inform all your current medications to the doctor prior to the test.
Inform your doctor if you are on any medications, have any allergies or underlying medical conditions before your Tuberculosis GeneXpert PCR Lymph Node Biopsy Tissue. Your doctor will give specific instructions depending on your condition on how to prepare for Tuberculosis GeneXpert PCR Lymph Node Biopsy Tissue.
The test results may be different depending on gender, age, health conditions, and other factors.
If the test results are negative it may indicate that there is no Mycobacterium tuberculosis DNA and not suffering from tuberculosis.
In case the test results are positive it may indicate that there is Mycobacterium tuberculosis DNA and suffering from tuberculosis.
