Alamar Biosciences vs Karius
Side-by-side comparison of AI visibility scores, market position, and capabilities
Alamar Biosciences develops the NULISA proteomics platform for ultrasensitive protein biomarker detection from minimal sample volumes; enables early disease detection and drug development research;
About
Alamar Biosciences is a Fremont, California-based life sciences company founded in 2020 with a focus on advancing proteomics through ultrasensitive biomarker detection technology. The company's flagship platform, NULISA (Nucleic acid-Linked Immuno-Sandwich Assay), enables researchers to simultaneously measure hundreds of protein biomarkers from very small sample volumes — including blood, cerebrospinal fluid, and other biological matrices — with sensitivity orders of magnitude beyond conventional assays like ELISA. This capability is critical for detecting disease-associated proteins at very early stages before symptoms manifest.
Karius raised $409M total including a $100M Series C in May 2024; its genomic blood test detects 1,000+ pathogens at 400+ U.S. hospitals; launched Karius Focus BAL for pneumonia in April 2025.
About
Karius is a Redwood City, CA-based life sciences company founded in 2014 that developed the Karius Test — a single blood draw that uses next-generation sequencing and AI to detect over 1,000 pathogens (bacteria, fungi, viruses, parasites) in seriously ill patients. The test is used when conventional cultures and targeted diagnostics fail, providing clinicians at transplant centers, children''s hospitals, and ICUs with a comprehensive pathogen report within 24 hours.
