Control lines are the foundation of lateral flow assay (LFA) validity, confirming proper test function and trustworthy results. Weak or inconsistent control line signals and batch-to-batch variability often cause delays, inaccurate results, and costly redesigns. Arista Biologicals solves these with precision-engineered lateral flow controls for drug-of-abuse testing, infectious disease diagnostics (COVID-19, HBV, HCV), fertility assays, veterinary, and other point-of-care applications.

Our portfolio of control antibodies and antigens for lateral flow assays delivers robust, consistent control line signals that validate reagent functionality and ensure accurate, reproducible results. Manufactured to strict quality standards, these reagents minimize variability for dependable performance. Whether you need validated LFA reagents or bulk supply for high-volume manufacturing, Arista provides the reliability and scalability you require.
