Need a Covid test? Call Healthline. OPINION: I got an odd phone call the other day. A woman wanted to know if she had reached Lucy Ferrin Ltd, and if the company did PCR testing. I said no and asked why she needed a PCR test. Covid, she replied. I advised her to call Healthline who would tell her where her nearest testing station was. She said she’d tried them and they were too busy. I told her I was sorry I couldn’t help, wished her well, and hung up. Why does she think Lucy Ferrin Ltd does Covid PCR testing? When I Googled Lucy Ferrin Ltd, the top hit was for a company called Dun and Bradstreet, which seems to be based in the United States and describes itself as “a leading global provider of business decisioning data and analytics”.
