Labs at some big-name hospital systems, such as Advent Health, the Cleveland Clinic and the University of Washington, are among those doing this. In addition, the FDA has approved more than a dozen testing kits by various manufacturers or labs under special emergency rules designed to speed the process. The kits are used in PCR machines, either in hospital labs or large commercial labs.
Roche won the first approval from the FDA for a test kit under emergency rules, and it has delivered more than , kits so far. That varies. Large commercial labs can do a lot. LabCorp, for example, said it is processing 20, tests a day — and hopes to do more soon. Other test kit makers and labs are also ramping up capacity.
Smaller labs — such as molecular labs at some hospitals — can do far fewer per day but get results to patients faster because they save on transit time. DNA is the genetic material that contains instructions and information for all living things. RNA is another type of genetic material. It contains information that has been copied from DNA and is involved in making proteins. How are they used? PCR tests are used to: Diagnose certain infectious diseases Identify a genetic change that can cause disease Find small amounts of cancer cells that might be missed in other types of tests.
How do they work? The sample is put in a special machine. An enzyme called polymerase is added to the sample. This causes the sample to produce copies. The copying process is repeated multiple times. After about an hour, billions of copies are made. If a virus or pathogen is present, it will be indicated on the machine. What happens during a PCR test?
