I suggest the Roche. Lloyd s pharmacy and Boots do free tests. I would suggest that he has one. He should not eat anything for 12 hours prior to the test. If it proves borderline then a gp should arrange a glucose tolerance test probably at the local hospital. This is again 12 hours prior not eating after the first blood test for the base line a glass of glucose is taken some 2 hours later another blood test is taken.
