This test is used to find out whether the individual is infected with tuberculosis TB or not by using a sample of synovial fluid.
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 Synovial fluid?
The thick viscous fluid between joints of the bone is called as the synovial fluid. The synovial fluid is generally clear and is made up of plasma and proteins which supplies nutrients to the joint structures and also plays a role in lubricating the bone joints to protect them from wear and tear. The contents of the synovial fluid tend to change in cases of certain infective diseases or disorders related to joints, bone and bone marrow
Why this test Is performed?
This test is performed to check the presence of tuberculosis DNA in the synovial fluid 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.

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 Synovial Fluid. Your doctor will give specific instructions depending on your condition on how to prepare for Tuberculosis GeneXpert PCR Synovial Fluid.
The test results may be different depending on gender, age, health conditions, and other factors.
