How can I be tested for progressive multifocal leukoencephalopathy because of the John Cunningham virus?

ANSWER

If your doctor thinks you might have progressive multifocal leukoencephalopathy (PML), you'll need an MRI (magnetic resonance imaging). This uses powerful magnets and radio waves to make detailed images and look for certain patterns in your brain tissue. Next, your doctor may want to do a spinal tap. He or she will use a needle to take spinal fluid from your lower back. If the virus is in this fluid, you have PML. If not, you may need a biopsy or other tests to find out for sure.
