Comments
This test is intended for use in the confirmation of immunity to VZV. In addition, seroconversion between acute and convalescent sera is considered strong evidence of current or recent infection. The best evidence for infection is a significant change on two appropriately timed specimens, where both tests are done in the same laboratory.
