Maybe difficulty getting swabs far enough in, especially for DC ?
But I'd like to know how many wasted tests were due to user error
and how many to lab mixups / losing tests / sample queued too long before processing etc
I remember when the Gov were struggling to meet their 100k a day target and then they suddenly rocketed up people on Twitter were reporting getting postal test containing swabs but no return label or return label but no swabs.
There was also no corresponding increase in people tested each day and there was speculation tests were being sent to drive in centres and 'counted' but not actually 'used' as it was so hard to meet the testing criteria.
I also read yesterday that care homes are now being sent double or triple the tests they request. These all count as tests made available.
There are obviously failed tests such as those sent to US for processing - was it 30k? Plus people who never take, never return it, take too long to return it, tests which are inconclusive. But I'd bet the bulk of the 'lost' tests are actually in a stock room at the Pillar 2 test centres or various care homes and were sent to help reach the testing targets.
