What is JCV status?
When someone says that they’re “JCV-positive,” or “JCV+,” they mean that they’ve had a blood test that was positive for anti-JCV antibodies. Most people with MS are likely to have been tested for the JC virus early in their treatment.
What is stratify JCV TM AB with index W RFL inhibition?
26029 Stratify JCV ™ Ab (w/Index) w/Rflx to Inhibition Assay (91665) The JC Virus (JCV) is associated with progressive multifocal leukoencephalopathy (PML). Detection of antibodies to JCV in serum OR plasma is a reliable indicator of exposure to JCV.
What is a high JCV index value?
Previously, different anti-JCV antibody index categories have been defined for PML risk stratification and the cut points 0.9 and 1.5 included in the label of natalizumab [8, 21]–in the following termed as low (≤0.9), medium (>0.9 and ≤1.5) and high (>1.5) JCV index category.
Can you recover from JC virus?
There is no way to cure JC virus or PML if it develops, but there are some ways healthcare providers will try to treat it. If you get sick, your healthcare provider will take several steps to give you the best chance at recovery.
What are JVC antibodies?
The JC virus antibody test, also called the Stratify JCV, is often performed before someone with multiple sclerosis (MS) is prescribed the drug Tysabri (natalizumab), which is a disease-modifying drug used to prevent relapse in people with MS.
What are the chances of getting PML while on Tysabri?
The risk of developing PML increases with the number of Tysabri infusions received. Tysabri is administered as a single intravenous infusion every four weeks. The overall worldwide cumulative rate of PML in patients who have received one or more Tysabri infusions is 0.5 cases of PML per 1,000 patients.
Can JC virus be cured?
There is no cure once the JC virus enters the brain and causes PML, but if the infection is caught soon enough there are treatments that may reduce the risk of longterm complications.
How do u get JC virus?
A doctor found it in the brain of a man with Hodgkin’s lymphoma and named the virus after them. Experts don’t know how it’s spread, but it’s thought that many people pick it up as kids through food or water that has the virus in it. It settles in your urinary tract, bone marrow, tonsils, or brain.
What does a positive JCV antibody mean?
If the blood test finds JC virus (JCV positive), this indicates that you are at a higher risk of developing PML, although for most people the risk is still small.
How does JC virus spread?
JC virus is spread via the urine-oral route. JC virus remains latent in the kidney epithelium cells, in bone marrow hematopoietic cells, in tonsillar lymphocytes, and in the brain. Although JC virus antibodies are detectable in most individuals, these antibodies cannot control JC virus reactivation and replication.
Can the JC virus go away?
What cells does JC virus infect?
J Neuropathol Exp Neurol. 2016 Aug;75(8):712-717.
What happens if you test positive for the JC virus?
If the blood test finds JC virus (JCV positive), this indicates that you are at a higher risk of developing PML, although for most people the risk is still small. The test does not indicate if you will or will not get PML.
How does the JC virus spread?
What causes JC virus?
What was the primary source from which the infection spread? PML is due to the reactivation of JC virus, a human polyomavirus, which causes a lytic infection of the oligodendrocytes in the brain. The asymptomatic JC virus primary infection occurs most likely as a result of urine-oral transmission in childhood.
Is stratify JCV approved by FDA?
Stratify Jcv Coding and Billing Guidelines On January 20, 2012, the US Food and Drug Administration (FDA) approved Stratify JCV Antibody ELISA Test, a diagnostic assay to detect the presence of anti-John Cunningham Virus (JCV) antibodies in patients with multiple sclerosis (MS) or Crohns disease (CD).

What is the CPT code for stratify JCV antibody inhibition assay?
If the Index Value is between 0.20-0.40 (inclusive), then Stratify JCV™ Antibody Inhibition Assay will be performed at an additional charge (CPT code: 86711). If the Index Value is between 0.20-0.40 (inclusive), then Stratify JCV™ Antibody Inhibition Assay will be performed at an additional charge (CPT code: 86711).
What is a reliable indicator of exposure to JCV?
Detection of antibodies to JCV in serum or plasma is a reliable indicator of exposure to JCV. The analytical performance characteristics were determined for multiple sclerosis patients.
