Rapid Diagnostic Tests (rdts)
overall review score: 4.3
⭐⭐⭐⭐⭐
score is between 0 and 5
Rapid Diagnostic Tests (RDTs) are portable, quick, and easy-to-use diagnostic tools designed to detect specific pathogens or biomarkers in various samples, such as blood, saliva, or urine. They are widely utilized in healthcare settings to facilitate immediate decision-making, especially in resource-limited environments where laboratory infrastructure may be lacking. RDTs significantly improve the speed of diagnosis for infectious diseases like malaria, HIV, and COVID-19, enabling prompt treatment and control measures.
