Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block] | NOTE 1: ORGANIZATION Biomerica Inc. and Subsidiaries (collectively the “Company”, “Biomerica”, “we”, “us”, or “our”) develops, patents, manufactures and markets advanced diagnostic and therapeutic products used at the point-of-care (physicians' offices and over-the-counter through drugstores and online) and in hospital/clinical laboratories for detection and/or treatment of medical conditions and diseases. Our diagnostic test kits are used to analyze blood, urine or fecal material from patients in the diagnosis of various diseases, food intolerances and other medical complications, or to measure the level of specific hormones, antibodies, antigens or other substances, which may exist in the human body in extremely small concentrations. The Company's products are designed to enhance the health and well-being of people, while reducing total healthcare costs. We are a global biomedical technology company that develops, patents, manufactures and markets advanced diagnostic and therapeutic products used at the point-of-care (in home and in physicians' offices) and in hospital/clinical laboratories for detection and/or treatment of medical conditions and diseases. The Company's products are designed to enhance the health and well-being of people, while reducing total healthcare costs. Our primary focus is the research and development of revolutionary, patented, diagnostic-guided therapy (“DGT”) products to treat gastrointestinal diseases, such as irritable bowel syndrome, and other inflammatory diseases. These products are directed at chronic inflammatory illnesses that are widespread and common, and as such address very large markets. Our medical diagnostic products are sold worldwide primarily in two markets: 1) clinical laboratories and 2) point-of-care (physicians' offices and over-the-counter drugstores). The diagnostic test kits are used to analyze blood, urine, or fecal specimens from patients in the diagnosis of various diseases and other medical complications, by measuring or detecting the existence and/or level of specific bacteria, hormones, antibodies, antigens or other substances, which may exist in a patient’s body, stools, or blood, often in extremely small concentrations. Due to the global 2019 SARS-CoV-2 novel coronavirus pandemic, in March 2020 we began redirecting and focusing a majority of our resources to develop, test, validate, seek regulatory approval for, and sell diagnostic products that indicate if a person has been infected by COVID-19. During fiscal 2021, we sold 2 primary types of Covid 19 tests; 1) antibody diagnostic tests that use a patient’s blood sample to detect if the patient has certain antibodies to COVID-19 that were created as part of their body’s immune response to a COVID-19 infection, even if the infection was asymptomatic, and 2) antigen tests that use a patient’s nasal fluid sample to detect if a patient is currently infected with the virus. Aside from the COVID-19 products we offer, the other products we sell are primarily focused on gastrointestinal diseases, food intolerances, diabetes and certain esoteric tests. These diagnostic test products utilize immunoassay technology. Most of our products are CE marked and/or sold for diagnostic use where they are registered by each country’s regulatory agency. In addition, some products are cleared for sale in the U.S. by the FDA.
