not needing a booster after susceptible titer?

[scorpionurse21]

I'm so confused I had my titers drawn for preemployment and I was susceptible to varicella. I called and asked if I needed another booster and they said no since I had proof of two doses. Wouldn't I need another vaccine if I don't have the immunity though?

It's weird that they had you get immunity testing in the first place if you met criteria for evidence of  immunity (for example if you've had two age-appropriate doses of vaccine).  Since they tested you now this comes into play:

Laboratory evidence of immunity: commercial assays can be used to assess disease-induced immunity, but they lack adequate sensitivity to reliably detect vaccine-induced immunity (I.e., they may yield false-negative results).
