Waldenström's macroglobulinaemia: three cases in shoe repairers.

Comment The results show a strong preference for home testing, although most patients had no experience of finger pricking. Many patients found the visit to the laboratory after fasting inconvenient. Patients produced significantly better blood spots than reagent strips, probably because it requires more practice to produce satisfactory strips. We conclude that patients find producing blood spots on filter paper or reagent strips at home and sending them by post before clinical review to be an attractive method of measuring fasting glucose concentration and cheaper than attending a laboratory.
