Latitude Food Allergy Care is an allergy clinic solely focused on food allergy. We are committed to changing the lives of families living with food allergies by creating access to exceptional care from diagnosis to lifesaving treatments to long-term support.

Learn about our board-certified allergist and clinical team who specialize in food allergy care.

At Latitude, we offer personalized and comprehensive care for food allergic patients and their families including:

  • Prevention
    • Early food introduction for infants (based on AAP Addendum, NIAID, BSACI and ASCIA Guidelines)
  • Accurate and clear diagnosis using the following:
    • patient food allergy history
    • skin testing
    • blood testing
    • food challenges (only to be done if a false positive is suspected).
  • Oral Immunotherapy (OIT), if appropriate, to desensitize patients to the foods they are allergic to using evidence-based protocols proven at Stanford University, UCSF, Baylor and other research institutions.
  • On-going care to support families who may not yet be interested in treatment but desire food-allergy-focused care to help them manage and understand the status of their allergies — allowing them to stay informed of current research and treatment options.
  • Long-term care for patients who have received treatment in clinical trials.

At Latitude, we are an allergy clinic 100% focused on food allergy.

  • We are the only allergy clinic affiliated with UCSF Benioff Children’s Physicians, a world-class network.
  • Clinical Team —  trained in food allergy treatment & care, providing 24/7 access to patients.
  • Patient Care Coordinators (PCC) — parents with personal experience with food allergies and OIT, to support patients and their families.
  • Food Challenge Availability — our clinical model enables us to offer quicker access to food challenges.
  • Clinical Space offers unique communal space that allows for a more comfortable experience and provides the opportunity to connect with families and build life-changing relationships.
  • Food Allergy Treatment — we currently offer Oral Immunotherapy (OIT) for single and multiple foods, with and without the use of Xolair (omalizumab). We offer treatment for all allergic levels including the most severe.  
  • Latitude welcomes patients with other allergic disorders, such as asthma and eczema, and we will treat those concomitant disorders within the context of comprehensive food allergy care. However, patients with asthma and environmental allergies can continue their care for those chronic conditions with their current allergist, or will be referred to a general allergist. 
  • We accept in-network insurance with a wide-variety of insurance carriers including Aetna, Anthem Blue Cross, Blue Shield, CIGNA, Health Net, United Healthcare.

Our aim is to partner with you to diagnose and care for your patients’ food allergies.

Ideal patient profiles include:

  • Patients with diagnosed food allergies
  • Patients where a food allergy is suspected, either by a physician or the individual, for accurate diagnosis
  • Patients you suspect have a misdiagnosed food allergy who are avoiding potentially safe foods, resulting in a negative impact on their quality of life. Refer for accurate diagnosis.
  • Infants with a higher risk of developing a food allergy to offer early food introduction in the interest of prevention. Risk factors include eczema.

Referrals can be sent directly via email to hello@latitudefac.com, phone 650-466-6224 or fax 650-466-6219.

We are also happy to provide your office with literature to handout to referred patients. Please contact us to receive or refill material.

Oral Immunotherapy (OIT) — a process that regularly exposes the patient to increasing amounts of the foods they are allergic to, with the goal of desensitizing the body and protecting against anaphylaxis secondary to accidental exposures.

For more background on oral immunotherapy with and without the anti-IgE Xolair (omalizumab), we recommend the following published studies and meta-analysis:

Thousands of patients have safely completed oral immunotherapy around the world. We have specific protocols in place to increase safety in office and at home during OIT, but it is possible to have an allergic reaction while going through OIT.

For more information about the risks and benefits of OIT, we recommend the following published studies and meta-analysis:

It is possible to have an allergic reaction while going through OIT. Our goal is to have a patient progress through treatment at a very slow and safe pace to reduce the risk of reaction and minimize unpleasant side effects.

We have several specific protocols in place to increase safety in office and at home:

  • Our board certified allergist is always in office during oral food challenges and OIT updosing appointments. 
  • Our office is fully equipped to manage anaphylaxis and we are located less than one mile from an emergency room.
  • We have a system of checks and balances to ensure that patients receive accurate dosing in the office and at home.
  • Patients have access to a medical hotline staffed by our clinicians 24/7, as well as, access to patient care coordinators who can help with compliance and safety issues.

We can treat any clinically diagnosed (IgE-mediated) food allergy. 

It is common for patients and even some healthcare providers to misdiagnose a food allergy. IgE-mediated food allergy can result in a life-threatening allergic reaction. On the other hand, a non-immune mediated adverse food reaction, while unpleasant, does not pose risk of anaphylaxis. When a non-immune mediated adverse food reaction is misdiagnosed as an IgE-mediated food allergy, a patient may unnecessarily restrict what they eat.

At Latitude Food Allergy Care, we take the necessary steps to accurately diagnose a food allergy to avoid unnecessary dietary limitations. This allows patients to bring some of their favorite foods back into their lives or to try new foods for the very first time.

From mild allergy to the most severe, allow us to collaborate with you on your patient’s care and determine if OIT may be beneficial. Each new patient will have a full medical examination and review by our medical team, led by a board certified Allergist and Immunologist, who will determine if OIT could be beneficial. Even the most severely allergic patient can benefit from OIT.

Xolair (omalizumab) is an anti IgE monoclonal antibody that works by inhibiting the allergic reaction process. It is FDA approved for use in asthma in children over age 6 and chronic urticaria in children over age 12. At Latitude, we offer Xolair in conjunction with OIT to increase safety for some patients. Xolair has been granted Breakthrough Therapy Designation for the prevention of severe allergic reactions to food allergy by the FDA, but this is currently an off label usage and is often not covered by insurance.

Yes, while focused on food allergy, our clinicians take extra steps with each visit to ensure that asthma and other allergic conditions are well-controlled. We encourage direct communication between our clinicians and the patient’s other providers to ensure these other conditions are monitored.

Our clinicians will carefully review all food allergy care options with a patient to determine the best customized plan for their family.

Yes. Please inquire to learn more about our in-network coverage with all major insurance plans.

We can often schedule an initial appointment with a referred patient within 48 hours. Our patient care model allows for the series of initial appointments needed for accurate diagnosis and a customized treatment plan to be completed quickly and efficiently. For patients’ convenience we offer early morning appointments, late afternoon appointments and a limited number of Saturday appointments.

Our first clinic is open in Redwood City, CA, in the San Francisco Bay Area. We have plans to expand nationally. As we grow, we welcome families from outside of the area and will personalize the care plan to accommodate the logistics of travel.

Our clinicians and staff are available to come to your practice to meet you and provide tailored presentations on food allergy to your providers and staff. We are also happy to arrange a tour of our clinic and we welcome your questions at hello@latitudefac.com or via our contact form.

Early introduction of peanut and egg is now recommended between 4 to 6 months of age. There may also be potential benefit to early introduction of dairy and wheat before 12 months. Within that recommendation it is important to accurately diagnose any suspected food allergy and take into account individuals who may be at higher risk of developing food allergies. Below is the current guidance from the AAP and NIAID, as well as a few of the pivotal studies, including the LEAP studies, that have dramatically shifted early introduction recommendations in the last few years:

We encourage pediatricians to refer infants where a food allergy is already suspected for accurate diagnosis. Infants with eczema and those at a higher risk of developing a food allergy can be referred to offer early introduction in the interest of prevention.
