However, <strong>many RDTs are known to have low sensitivity<\/strong>, which refers to the test\u2019s ability to correctly identify people who <em>do<\/em> have the disease (true positives).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Low sensitivity leads to <strong>high false negative rates<\/strong>, meaning the test fails to detect the disease even when the individual is actually infected. This can be problematic for several reasons:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Public Health Risk<\/strong>: Infected individuals who test negative might unknowingly spread the disease to others.<\/li>\n\n\n\n<li><strong>False Sense of Security<\/strong>: Patients may not seek further care or follow preventive measures.<\/li>\n\n\n\n<li><strong>Delayed Treatment<\/strong>: Critical diseases like malaria or COVID-19 require timely treatment; a false negative result can delay medical intervention and worsen outcomes.<\/li>\n<\/ol>\n\n\n\n<h4 class=\"wp-block-heading\">Why Are Some RDTs Less Sensitive?<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Sample Quality<\/strong>: RDTs may require specific sample types (e.g., blood, saliva, nasal swabs), and poor sample collection can reduce accuracy.<\/li>\n\n\n\n<li><strong>Low Pathogen Load<\/strong>: In early stages of infection, the level of virus or antigen in the body may be too low for detection.<\/li>\n\n\n\n<li><strong>Test Limitations<\/strong>: Some RDTs rely on antigen-antibody reactions, which may not be strong enough to detect low levels of the pathogen.<\/li>\n\n\n\n<li><strong>Storage Conditions<\/strong>: Heat and humidity can degrade test kits, especially in remote or tropical areas.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Despite these issues, RDTs are still useful for <strong>screening<\/strong>, especially in areas with limited laboratory infrastructure. However, <strong>negative results in symptomatic patients often need confirmation with more sensitive methods<\/strong> like PCR (polymerase chain reaction) or ELISA (enzyme-linked immunosorbent assay).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Summary:<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Most rapid diagnostic tests have low sensitivity, leading to high false negative rates.
