Your Initial Appointment with Mitochondrial Medicine

Prior to your initial appointment

Before scheduling an appointment with one of our physicians, we will need to review your child's or the adult patient's medical records. The Medical Records and Reports Checklist below outlines what records you’ll need to submit to the clinic.

Please send relevant paperwork as soon as possible via fax, e-mail or direct mail. Records can be faxed to the "Mito Center" attention at 215-590-0583 with a fax cover page noting: “Requesting appointment with Mitochondrial Medicine,” emailed to mmfp@email.chop.edu, or mailed to:

Children's Hospital of Philadelphia
Abramson Research Center 
Mitochondrial Medicine

The patient's primary care physician or other specialists may also reach out to us to share records or request a consultation.

An electronic survey will need to be completed by your family prior to the visit.

Scheduling an appointment

Once all medical records have been received and reviewed, you or your child will be placed on a wait list for an appointment. We will contact you to schedule an appointment when one becomes available. Urgent add-on appointments are possible within 1-2 weeks if all records are available, an appropriate medical indication is present, and a physician referral is made to support this appointment.

We strongly recommend that you contact your insurance company to determine your coverage for diagnostic testing, including genetic studies. Depending on your carrier, pre-authorization is frequently needed to allow blood and urine testing to be performed on the day of your visit at Children’s Hospital of Philadelphia, and many genetic studies may only be possible to be performed at a Children's Hospital of Philadelphia laboratory.

One to two weeks prior to your scheduled appointment, a member of our team may contact you to ask for any additional information needed, such as your family history, to ensure a complete understanding of the patient's condition and background to best prepare for your visit. This detailed preparation will help make your visit as productive as possible.

Day of your visit

Mitochondrial Medicine is located on the 2nd floor of the Wood Center. You may park underneath the Wood Center and proceed to registration on the 2nd floor of the Wood Center.

What to expect at your appointment

Your child’s appointment will involve an extensive evaluation by one of our physicians during which they will confirm relevant medical findings with you, perform a detailed physical examination, and initiate any recommended diagnostic biochemical and genetic laboratory testing.

Our team will provide you with relevant mitochondrial disease counseling based on your or your child’s diagnosis, including an overview of mitochondrial disease features and genetics. We will also discuss the availability, benefits and limitations of different avenues of testing, as well as discuss initiating any supplement or vitamin therapies.

We will also make referrals to other specialists as needed to ensure coordinated long-term care. The following specialists are often involved in the care of patients with mitochondrial disease:

Because we have so much to cover during your visit, please plan to spend a minimum of four hours at CHOP for your appointment.

After your visit

The focus of the Mitochondrial Medicine Clinic is to work towards clearly identifying the presence of mitochondrial dysfunction and clarify the underlying cause of suspected mitochondrial disease. This includes optimizing multidisciplinary care and precision medicine long-term for confirmed patients with definite, primary mitochondrial disease. We do not provide the day-to-day medical management for your or your child’s medical concerns. It is important that you have a dedicated physician for ongoing medical needs, such as your primary care doctor and appropriate specialists for organ specific problems such as neurologist, cardiologist, endocrinologist, etc.

If genetic testing was recommended at your initial visit, results are typically available within up to 4-8 months depending on insurance approvals to initiate testing. At this time, a member of our team will contact you to schedule a follow-up appointment to discuss these results in more detail.

Annual follow-up appointments are typically recommended for those with a strong suspicion of mitochondrial disease with no known genetic cause. Individuals with definite mitochondrial disease are followed up at regular intervals determined by their age, disease severity and unique medical needs.
