description Sensitivity and specificity of rapid antigen detection tests (RADTs) for detection of group A hemolytic streptococcus (GAS) vary. The purpose is to present the first SKUP (Scandinavian evaluation of laboratory equipment for point of care testing) evaluations concerning the assessment of the diagnostic performance and user-friendliness of two RADTs for detection of GAS when used under real-life conditions in primary health care. Throat samples were collected in duplicates at primary health care centers (PHCCs) from patients with symptoms of pharyngitis. The performance of QuickVue Dipstick Strep A test (307 samples) and DIAQUICK Strep A Blue Dipstick (348 samples) was evaluated using culture results at a clinical microbiology laboratory as comparison. The user-friendliness was evaluated using a questionnaire. The diagnostic sensitivity was 92% (90% confidence interval (CI) 87–96%) and 72% (90% CI 65–79%), while the diagnostic specificity was 86% (90% CI 81–90%) and 98% (90% CI 96–99%) for QuickVue Dipstick Strep A test and DIAQUICK Strep A Blue Dipstick, respectively. Both RADTs obtained acceptable assessments for user-friendliness and fulfilled SKUP’s quality goal for user-friendliness. The diagnostic sensitivity for QuickVue Dipstick Strep A test and the diagnostic specificity for DIAQUICK Strep A Blue Dipstick in this objective and supplier-independent evaluation were higher compared with previous meta-analyses of RADTs. However, the diagnostic specificity for QuickVue Dipstick Strep A test and the diagnostic sensitivity for DIAQUICK Strep A Blue Dipstick were lower compared with previous meta-analyses of RADTs.
