MADRID — Some political leaders are hailing a potential breakthrough in the fight against COVID-19: simple pin-prick blood tests or nasal swabs that can determine within minutes if someone has, or previously had, the virus.
The Spanish government on Friday said it already sent back a batch of 58,000 rapid antigen tests from a Chinese producer because the first 8,000 proved flawed. It said the producer agreed to replace the returned tests and another 582,000 tests ordered with kits that would meet requirements. Health authorities in China, the United States and other countries have offered few details on the rates of false positive and false negative results on any coronavirus tests. Experts worry that the rapid tests may be significantly less reliable than the more time-consuming method.
Antibody tests are most valuable as a way of seeing who has been infected in the recent past, who became immune to the disease and — if done on a wide scale — how widely an infection has spread in a community. For most people, the coronavirus causes mild or moderate symptoms, such as fever and cough that clear up in two to three weeks. For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia, and death. Most people recover.
