About This Practice

St. Louis Family Allergy cares for allergy, asthma and immunology patients in St. Louis, St. Peters and surrounding Missouri communities, according to its website. Its primary office is in St. Peters, and it added this office at 8888 Ladue Road. The website doesn't say which office provides Quick-LI, so ask when you schedule. Quick-LI is the practice's intralymphatic immunotherapy, a procedure it says was named and refined by Dr. Brynn Everist in Kansas City. Small allergen doses go into a lymph node in the pelvic region under ultrasound guidance, in three visits with increasing doses, one a month. Each procedure takes about 5 to 10 minutes, followed by an hour of monitoring. The practice uses Quick-LI for environmental allergies such as dust mites, pets, pollens and molds. It says the treatment isn't for people with active cancer, serious autoimmune disease or a pregnancy, and that relief should come by about four months after the first injection. Other services listed include allergy testing, allergy shots, biologic therapy and patch testing. Dr. Sonia Cajigal Allergist and immunologist
