Thanks Malcolm. Your explanation has set my mind at rest. Was in hospital with diverticular perforation, but when doing blood analysis, full blood count. LFT's etc, they also discovered my LFT results were as they described "wonky". As a am a retired registered nurse, I asked for an explanation of "wonky", but got little in return. As I only drink alcohol very infrequently (a few glasses of wine every two months or so) I tried to find out what can cause irregularities in the LFT's but to be honest got absolutlely nowhere. I wondered if this was the reason they issued me with a card. I have been having problems even handling a few glasses of wine - it seems to have a very adverse reaction, sometimes making me feel quite ill (sometimes, but not always) Thanks v. much Janette (weescot48)
