The UK is aiming to carry out 100,000 coronavirus tests a day by the end of April, Health Secretary Matt Hancock said, as he announced a “five-pillar strategy” for testing.
It comes as the government was criticised for not increasing the number of tests more quickly.
Currently, there are around 10,000 tests being carried out a day.
The 100,000 target includes both swab tests, which are already in use, and blood tests that are not yet launched.
The number of people with the virus who have died in the UK has risen by 569, taking the total to 2,921 as of 17:00 BST on Wednesday.
