Covid-19: Test Results

Lord Robathan Excerpts

Tuesday 27th October 2020 Lords Chamber

[Lord Bethell (Con)]

The noble Baroness is right to cite the use of wastewater analysis. The innovations and partnerships team at test and trace has a programme to look at precisely that method. We are particularly interested in using targeted wastewater analysis at schools and in social care in order to promptly identify the presence of the disease. We are looking in particular at technologies that have already been trialled in Italy. The trials are extremely promising, but I would be happy to make that connection between South West Water and the relevant team so that their knowledge is usefully used.

[Lord Robathan (Con)]

My Lords, what study has been undertaken into the efficiency and accuracy of these tests; by which I mean how many false positives and false negatives there are? Furthermore, what is the long-term strategy regarding this? If, every time restrictions are relaxed, tests show that infections rise, are we then just to continue imposing lockdowns ad infinitum?

[Lord Bethell (Con)]

My Lords, we have a very intense and rigorous validation programme around the various tests. They look at sensitivity and false positives. We do not believe that the current machines we use have a high risk in that department, but we always keep a close look at it. I am extremely grateful to those businesses that have developed new and innovative tests that we are rolling out all the time.
