We currently offer PCR nasal swab testing only. We hope to offer rapid tests and antibody tests in the near future.
We have a national account with Quest Diagnostics.
Due to the large volume of testing being done at this time, we are seeing results come back between 3-5 days. A handful of tests have taken seven days to come back. Priority is given to patients preparing for surgery, people living in congregate care settings, and hospitalizations.
You can receive results by phone call, text message, email, or by logging into our HIPAA compliant patient portal.
We accept all major insurance providers and healthshares, including Medicare and Husky. You may be billed an in-network office visit copay, but in most cases insurance waives copays for COVID-related care.
Please see complete list under Dr. Berchelmann’s profile.
We charge $150 per person for an at-home visit. This is not covered by insurance and will be collected when appointment is scheduled. We are committed to caring for all people regardless of their ability to pay. If you have financial concerns please discuss this with Dr. Berchelmann.
