You can receive timely care for many injuries or illnesses. We offer X-rays, vaccines, EKGs, pregnancy tests, STD tests, other lab tests and blood draws. We are located within Lahey Health Hub and are connected to the Lahey Health My Chart system — which allows us to conveniently access your medical records.
