About IQuity

IQuity is a life science technology company leveraging machine learning methods to deliver breakthrough RNA diagnostics and analytics. The company’s initial offerings include Isolate tests across neurology, gastroenterology and rheumatology that are based on proprietary algorithms capable of ruling in or ruling out specific autoimmune diseases. The accuracy of these methods at the earliest onset of symptoms exceeds 90% and offers providers the ability to shorten the diagnostic process for autoimmune disease and related conditions. Most autoimmune diseases take months to years to diagnose. IQuity’s technology, IQIsolate, analyzes RNA expression data from a blood sample to identify presence or absence of disease at the cellular level and deliver a result to providers in only 7 days. RNA expression is representative of the presence of disease in real time, whereas changes in DNA indicate potential risk of disease.

Early diagnosis and treatment lead to optimal patient outcomes by reducing long-term, irreparable damage to the body and lowering lifetime healthcare costs. IQuity is firmly committed to data transparency and scientific peer review and will perform its tests in its independent CLIA-certified lab.


IQuity’s mission is to relentlessly pursue innovation in specialized diagnostic and analytic technology to identify complicated autoimmune and autoimmune-related diseases at the earliest signs of disease.

  • Enable providers to diagnose early and treat sooner in the disease progression
  • Lower the overall cost of life-long autoimmune disease
  • Minimize patient uncertainty and fear, which is often associated with traditional, protracted testing methodologies
