OBJECTIVES: To analyze the effect of blood collection and storage conditions on activity of α-galactosidase A, arylsulfatase B and α-glucosidase. DESIGN AND METHODS: Blood was collected in EDTA, heparin, or direct spotting on filter paper and stored at different temperatures (-20, 4, 25 and 37°C) and storage times (3, 10, 17 and 180days). The influence of filter paper size was also assessed (3.0 and 1.2mm). RESULTS: No statistically significant difference was observed between the three collection methods. α-Glucosidase A activity significantly decreased after the 10th day, while arylsulfatase B activity only differed significantly after the 180th day, and α-galactosidase A activity remained constant throughout this storage time. Excellent correlation coefficients were observed for the two filter paper sizes used. CONCLUSIONS: Both paper sizes may be employed. Filter paper specimens should be transported under refrigeration as soon as possible after blood collection.
