I recently took a Varicella IgG Titer and it came back?
The results say:
Test: Varicella ZsIgG
Reference Range: AI
What does that mean?

You were tested for a type of antibody that develops after a previous infection or vaccination to Chicken pox.
AI stands for antibody index. The reference range seems to be missing in your post but it is usually around 1.0 or 1.1 for that test which would mean your result of 4.7 indicates immunity to the Varicella/chicken pox virus.
