Request a price quote

Before you request a price quote, remember that we offer testing at 500 locations worldwide, and most of these locations and prices are already posted on our website. If you are requesting a quote for a location or circumstance not listed on our website, or are having trouble finding our locations, complete this request form.   Once you submit your request you will receive an email response within one business day. For fastest service you can find the prices online by using our self serve feature.  If you are seeking an in-home exam, please include that note in the “additional info” field but be aware that in-home exams are always more expensive than coming to one of our established offices.

We will email you a price quote for our nearest testing location
