Type Insights

Based on type, luminometric ATP assays accounted for the largest share of the U.S. ATP assays market in 2024. This dominance is due to their high sensitivity, fast results, and ability to work across many applications-from drug testing to food safety and environmental monitoring. These assays help detect very small amounts of ATP, making them helpful in checking cell health, identifying contamination, and ensuring product safety in regulated industries. As U.S. laboratories and production facilities focus more on quality control and regulatory compliance, luminometric ATP assays are widely used to support accurate and reliable testing. Products such as the Luminescent ATP Detection Assay Kit are commonly used to measure cell activity, assess drug effects, and support research in areas such as microbiology, cancer, and toxicology-using a simple process of breaking the cells, adding reagents, and measuring light output with a luminometer.

Enzymatic ATP assays are expected to grow at the fastest CAGR in the U.S. ATP assays market during the forecast period. These assays use the enzyme luciferase to trigger a bioluminescent reaction between ATP and luciferin, producing light that can be accurately measured. Because this reaction is particular to ATP, enzymatic assays allow for precise detection even at very low concentrations. This makes them highly valuable in clinical diagnostics, pharmaceutical research, and environmental testing in the U.S. In healthcare, they detect microbial contamination, check hospital cleanliness, and identify infections. In pharmaceutical labs, enzymatic ATP assays test cell health and measure how drugs affect biological systems. Their reliability and sensitivity support high standards in research and quality control.
