respirator acut sever 2 (SARS-CoV-2) pentru pacienții internați
Abstract
Trusele de detectare rapidă a antigenului (RAD) pentru sindromul respirator acut sever coronavirus 2 sunt utilizate pe scară largă ca test de screening primar în Japonia, deoarece diagnosticul rapid al bolii coronavirus 2019 (COVID-19) este esențial pentru controlul infecției. Raportăm cazuri cu rezultate fals pozitive ale testului RAD într-o secție pentru pacienții cu dizabilități. Testele RAD pot evoca riscuri operaționale ale spitalului. Este de dorit ca efectuarea corectă a testului PCR atunci când pacienții sunt internați într-o secție de tratament medical cu simptome COVID-19.

Testarea microbiologică a bolii coronavirus 2019
Abstract
Diagnosticul microbiologic al bolii coronavirusului 2019 (COVID-19) se efectuează în principal prin testul de amplificare a acidului nucleic (NAAT) și testul antigenului. Deși NAAT este testul de diagnosticare standard, utilizarea acestuia este limitată de resursele insuficiente de laborator și de timpul lung de răspuns. Au fost introduse teste NAAT la punctul de îngrijire pentru a remedia aceste neajunsuri, dar sensibilitatea lor variată și constrângerile de resurse rămân o preocupare. Testele antigenului necesită mai puține resurse, dar au o sensibilitate redusă. Cu toate acestea, testele de sensibilitate scăzută pot fi utile în funcție de situație. În contrast, în unele faze clinice ale COVID-19, testele de înaltă sensibilitate pot oferi rezultate fals negative. Prin urmare, este necesară strategia corectă de testare pentru un diagnostic precis. În această recenzie, sunt discutate caracteristicile și aplicațiile clinice ale testelor microbiologice disponibile în Japonia (NAAT, testul antigenului și testul anticorpilor). Diagnosticul clinic al COVID-19 este ușor complicat, iar cazurile în care infecția se răspândește de la indivizii infectați asimptomatic sunt numeroase; prin urmare, diagnosticul de laborator este esențial pentru a preveni transmiterea ulterioară.
