My dad, 86, was in contact with someone who subsequently tested positive. My dad did a lateral flow test which was positive. He reported it online and got a pcr home test to do a couple of days later. The results came back negative. The following day he did another lateral flow test which again showed positive. He then booked an appointment at a test site and the HCA there did the test for him. Today it has come back negative. He has been advised by the 119 service that the pcr results will be accurate and to ignore the lateral flow test results.
Is this common?
