Question: 

My son had chicken pox when he was young. Is there a test provided to confirm immunity to virus? He requires this for U.S. college.

Answer: 

There is a test that can confirm immunity to chicken pox. Please see your family doctor for a requistion for blood work.

If the blood test reports no immunity, please follow-up with your local public health unit to have them recommend and provide any publicly funded vaccine. You will find the number for your local health unit here.
