the current shortages of laboratory consumables and reagents affect diagnostic capacity and hamper the epidemic response at the national and local levels. The laboratories have experienced delayed or missing deliveries of swabbing material, plastic consumables, RNA extraction and RT-PCR reagents, and PPE. This is affecting laboratories in all EU/EEA countries.
South Dakota, said that her state's public-health laboratory—the only lab doing COVID-19 testing in the state—had so much trouble securing reagents that it was forced to temporarily stop testing altogether. also noted critical shortages of extraction kits, reagents, and test kits
extract the virus's genetic material—in this case, RNA—using a set of chemicals that usually come in pre-assembled kits. 'The big shortage is extraction kits' There are no easy replacements here: 'These reagents that are used in extraction are fairly complex chemicals. They have to be very pure, and they have to be in pure solution'

Indeed, the rapid tests that arrived from China a few days ago do not really reliably detect the infection at an early stage.
None of the antibody tests ordered by the government is good enough to use, the new testing chief has admitted. Professor John Newton said that tests ordered from China.
