Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block] | NOTE 1: ORGANIZATION Biomerica, Inc. and its subsidiaries (which includes wholly-owned subsidiaries, Biomerica de Mexico and BioEurope GmbH) is a biomedical technology company that 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, nasal 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. Our primary focus is the research, development, commercialization and in certain cases regulatory approval, of 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 InFoods® IBS product uses a simple blood sample and is designed to identify patient-specific foods that, when removed from the diet, may alleviate IBS symptoms such as pain, bloating, diarrhea and constipation. Instead of broad and difficult to manage dietary restrictions, the InFoods® IBS product works by identifying a patient’s above normal immunoreactivity to specific foods. A food identified as positive and causing an abnormal immune response in the patient is simply removed from the diet to help alleviate IBS symptoms. Our existing 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 like Walmart and Walgreens). The diagnostic test kits are used to analyze blood, urine, nasal or fecal specimens from patients in the diagnosis of various diseases, food intolerances 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 developing COVID-19 products to indicate if a person has been infected by COVID-19 or is currently infected. While we offer a COVID-19 antibody diagnostic test to determine if a person has previously been infected by the COVID-19 virus, all of our COVID-19 revenues in fiscal 2022 have come from international sales of our COVID-19 antigen tests that use a patient’s nasal fluid sample to detect if the patient is currently infected with the virus. The other existing products that contributed to our 2022 revenues are primarily focused on gastrointestinal diseases, food intolerances, 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 United States by the FDA.
