Coronavirus Testing Hampered by Disarray, Shortages, Backlogs
State officials and labs say competition for supplies and questionable results are prolonging the national crisis. The White House put the onus on states to figure out a strategy, while saying there is sufficient capacity.
That marquee effort soon ran into the supply-chain issues that have plagued the testing buildup. State officials found they couldn’t easily obtain enough of Abbott’s single-use cartridges to actually test patients, they said. Each cartridge contains the chemicals and other components needed for the machine to process one test. As of last week, Abbott said it had distributed about 600,000 cartridges for the machines. “We understand there is great demand from both the public and private sectors for our rapid point-of-care test,” said Scott Stoffel, Abbott’s spokesman. “We’ve been clear from the outset on what we could initially provide, and we’ve met every commitment.”
In recent days, state and hospital officials found in internal studies that the devices frequently produced inaccurate results, leading at least one hospital to return the devices, they said in interviews. hMr. Stoffel said the company believes the inaccurate results are rare, and said it has made changes to its instructions for using the machines to address them.
