Welcome to Aperture Immunodiagnostics, formerly known as Foundation Labs and TPIRC Diagnostics.The Southern California Food Allergy Institute, spearheaded by Dr. Inderpal Randhawa, a leading specialist in internal medicine, pediatrics, immunology, allergy and pulmonology, specializes in treating a multitude of potentially life-threatening food and environmental allergies. To guide a patient’s unique and highly specialized treatment plan for anaphylaxis therapy, it is critical to ensure access to the full panel of diagnostic data that is required to develop a patient’s individualized treatment plan in an accurate and timely manner.  Due to the esoteric nature of all requested allergy tests necessary in this specialized treatment, these laboratory tests cannot be performed or are not available at most major national laboratories due to the proprietary nature of the test as well as the availability of these specialized tests on their test menu.  There are no other laboratories that are capable of doing these tests in their entirety. Due to this limitation, the inception of Aperture was created in order to bridge the gaps between allergy test availability, turnaround time of those results, as well as offering a diverse array of other diagnostic options such as pediatric pulmonology.
