  • For our expedited next day PCR test for $75, the cost is an administrative fee, and if you use your insurance information, we (Preston’s Pharmacy) will not be able to bill it to your insurance directly, instead, Principle Lab will be the one billing your insurance for the lab fees. You will only pay the prices shown on our website and any additional bill that you receive, might be an explanation of benefits or copies of bills that the lab had sent to your insurance.

Please arrive at your scheduled time, coming from Lee Highway, turn onto Edison St, following the signs to turn left into the alleyway (just past the entrance to the pharmacy parking lot) toward the back of the pharmacy, and into your designated spot. These spots will be clearly marked.
