WebPCR tests work by: Taking a sample of blood, saliva, mucus, or tissue. The sample will contain your own DNA and possibly the DNA of a pathogen or cancer cell. The sample is put in a special machine. An enzyme called polymerase is added to the sample. This causes the sample to produce copies. WebThis COVID-19 PCR test is typically used to meet requirements for pre-flight testing, event entrance, or school and workplace screening. If you have symptoms or recent exposure, Labcorp COVID-19 PCR testing is also available through pharmacy drive-thrus, urgent care centers, and healthcare providers.
