Immunochromatographic Test Strips
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
Immunochromatographic test strips, also known as lateral flow assays, are portable, easy-to-use diagnostic devices designed to detect the presence or absence of specific target analytes such as pathogens, biomarkers, or drugs in biological samples. These test strips function by using antibodies embedded on a membrane that bind to the target substance, producing a visual result typically in the form of colored lines within minutes. Widely employed in medical diagnostics, food safety, and environmental testing, they offer rapid and on-site testing capabilities.
