Teotten Diagnostics

Teotten is a Spanish biotechnology company specializing in the assessment of T-cell mediated immunity through innovative diagnostic tools. Spun off from the Spanish National Research Council (CSIC), the company utilizes a proprietary platform to quantify cellular immune responses, offering a deeper understanding of long-term protection against pathogens compared to standard serological tests. Their primary commercial offering is a diagnostic test for SARS-CoV-2 immunity, which measures the activation of T-cells upon exposure to viral antigens. Teotten is currently leveraging its technology to develop diagnostic applications in oncology, organ transplantation, and other infectious diseases. The company's approach provides critical data for personalized medicine, helping clinicians determine the necessity of vaccine boosters and monitor immune health in immunocompromised patients.
