Dosage: One time
Advice & Tips: Normally administered as a precautionary discovery due to the potentially life threatening aspect (PML) of the JC virus when taking or considering taking Tysabri. I only did this to discover if I had the JC virus antibody. It may have meant I had PML instead of MS.
Cost: < $25 monthly
