[110] [111] US CDC developed its own testing kit after China shared the genetic sequence on 10 January and deployed it to detect the first coronavirus case. The testing kit used three small genetic sequences instead of two used by Germany. The test kits were found to be defective because the third sequence, or "probe", gave inconclusive results ...

Genetic testing is often done as part of a genetic consultation and as of mid-2008 there were more than 1,200 clinically applicable genetic tests available. [23] Once a person decides to proceed with genetic testing, a medical geneticist, genetic counselor, primary care doctor, or specialist can order the test after obtaining informed consent .

The WHO did not offer any test kits to the U.S. because the U.S. normally had the supplies to produce their own tests. [3] The United States had a slow start in widespread SARS-CoV-2 testing. [4] [5] From the start of the outbreak until early March 2020, the CDC gave restrictive guidelines on who should be eligible for COVID-19 testing. The ...
