UPCRISULAPIULULUIJM 4 Question 6 What are some differences between both, Sherlock and RT-PCR, AND the serological test? Serological tests allow to detect individuals currently with the disease and that had the disease in the past. Serological tests require blood samples while the others can use nasal secretions. Serological tests detect human antibodies against COVID19 while the other tests detect viral genes. Serological tests detect viral genome while the other tests focus on viral RNA Question 7 6 p Regarding the...

D Question 7 6 pts Regarding the serological test, which of the following are true statements: The test can potentially inform when social distancing is no longer needed because it detects how many people are already immune to the disease. The test can detect whether the infection is active or inactive The test gives false positives when exposed to dengue and other coronaviruses' antibodies. The test available shows fluorescence when antibodies present in blood extracted detect the spike protein...
