I go for my INR blood test, usually at the pathology lab at the hospital. The first one I went for during lockdown they ran in the outpatients department with strict social distancing signs on seats and very few people there. The nurse who took my blood told me to book in for my next one at a more local blood clinic, which I did, it was a community centre, and you waited in the large hall and seats were set out for social distancing. You went inside he door and out of another. Nurses wore masks and gloves, gloves they changed after every patient. I have to go again in June. I wore a mask and gloves too, as an extra precaution, but nurse did say as long as I wash my hands or use anti bac gloves are so essential. Your health is important so do not miss an appointment that is important to you. If are really concerned, come home put all your clothes in the wash and shower.
