JC virus - DNA detection by PCR - Urine Test, Price, Normal Range - Sprint Diagnostics Hyderabad
Patient Preparing : No special preparations needed.
The John Cunningham virus, or JC virus, is a type of human polyomavirus that is very common and harmless in most people. However, in individuals with compromised immune systems, such as those with HIV/AIDS or those undergoing immunosuppressive therapy following an organ transplant, the virus can reactivate and cause a serious brain disease known as progressive multifocal leukoencephalopathy (PML).
The JC Virus - DNA Detection by PCR - Urine test is designed to detect the presence of JC virus DNA in your urine. Polymerase Chain Reaction (PCR) technology, known for its high sensitivity and specificity, is employed for the detection. It can identify even tiny amounts of the virus, offering an early indication of potential reactivation of the JC virus.

Why is the JC Virus - DNA Detection by PCR - Urine test ordered?
This test is typically ordered if you exhibit signs of PML or if you're at a high risk for the condition, such as having a weakened immune system due to HIV/AIDS, undergoing organ transplant, or receiving immunosuppressive drugs.
What does a positive result indicate?
A positive result indicates that JC virus DNA is present in your urine, suggesting an active infection. However, a positive result alone does not confirm PML, as the disease is associated with the reactivation of JC virus in the brain. Additional diagnostic procedures may be necessary.

What is progressive multifocal leukoencephalopathy (PML)?
PML is a serious brain disorder caused by the reactivation of the JC virus in people with severely weakened immune systems. The condition leads to damage in the white matter of the brain, resulting in progressive neurological symptoms.
4. How is the urine sample for the test collected?
The urine sample is typically collected in a clean, sterile container. You may be asked to provide a "clean-catch" sample, which involves cleaning the genital area before urinating and collecting the midstream urine to avoid contamination.
What kind of symptoms can be associated with PML?
PML symptoms vary based on the specific areas of the brain affected and may include cognitive changes, visual disturbances, muscle weakness, impaired coordination, and speech difficulties.
Can a healthy person be infected with JC virus?
Yes, JC virus infection is actually very common, and most people are infected during childhood. The virus remains dormant in the kidneys and does not cause any problems in individuals with a healthy immune system.
How is PML treated?
Currently, there's no cure for PML. Treatment is mainly focused on improving or stabilizing the immune system, usually by altering or discontinuing immunosuppressive treatments.
Can I have an active JC virus infection without symptoms?
Yes, it is possible to have an active JC virus infection without symptoms. Regular testing is especially crucial for people at high risk for PML.
How often should I get tested for JC virus?
The frequency of testing is determined by your healthcare provider, based on your individual health situation and risk factors.
Can other conditions cause reactivation of the JC virus?
Yes, any condition or medication that severely weakens the immune system could potentially trigger the reactivation of JC virus, such as certain types of cancers and their treatments.
What does a negative test result mean?
A negative result means no JC virus DNA was detected in your urine. However, it does not necessarily mean you are not infected with the virus; the virus might just not be present in the urine at the time of testing.
Can this test be performed on children?
This test can be performed on individuals of all ages, but PML is extremely rare in children.
What should I do if my test results are positive?
If your results are positive, it's important to consult with your healthcare provider to understand the implications and discuss further diagnostic or treatment options.
Can this test be done at home?
No, this test requires professional collection and handling of a urine sample, and must be performed in a medical or laboratory setting.
Is there a vaccine against JC virus?
As of now, there is no available vaccine to protect against JC virus.
Can the presence of the JC virus in urine indicate an active infection in other parts of the body?
While the presence of the JC virus in the urine indicates an active infection, it does not necessarily imply an infection elsewhere in the body. The JC virus typically remains dormant in the kidneys and urinary tract in healthy individuals, but may reactivate and cause diseases like PML in individuals with weakened immune systems.
Can PML be prevented?
There's no specific way to prevent PML, but keeping your immune system healthy is the key. For individuals at high risk, regular monitoring and early detection of the reactivated JC virus can contribute to early intervention and better disease management.
Can a negative result rule out the possibility of PML?
No, a negative result cannot rule out the possibility of PML. This is because the test detects the presence of the JC virus in the urine, but PML occurs when the virus is active in the brain. Thus, other diagnostic tests may be needed if PML is suspected.
