Proteins are critical for the normal functioning of the human body. They provide structure, transmit and receive information, and carry out important chemical reactions. In persons with a disease, many proteins may be affected. Compared to normal health, some proteins may become overly abundant, while others may become scarce. By measuring these proteins—or biomarkers—SomaLogic is discovering new insights into disease and health. By combining biomarkers into patterns or disease signatures, SomaLogic is bringing new levels of accuracy to virtually every aspect of patient care: disease screening, diagnosis, therapy selection, and patient monitoring. SomaLogic uses its unique aptamer array technology and bioinformatics capabilities to discover disease-specific biomarkers and protein signatures. Using a simple blood test, clinicians will have the information to transform medical practice and make a real difference in people's lives. The approach can be applied across a broad spectrum of clinical challenges faced by physicians. Proteins say a lot about a person, and SomaLogic is discovering what they say.
