We compared acid citrate-dextrose (ACD-B) and heparin to determine which anticoagulant better preserves leukocytes for lysosomal enzyme assays if processing was done immediately or delayed for 24 h or more. Twenty normal subjects had blood drawn into tubes containing either ACD-B or heparin. The leukocytes were isolated by sedimentation in dextran (50 g/L) less than 2, 24, 48, and 72 h later. The most apparent difference was that cell counts indicated a 30% reduction in the number of leukocytes for ACD-B and a 95% reduction for heparin-treated cells at 48 h. The neutrophil function assay indicated that leukocyte processing must be done in less than 24 h regardless of the anticoagulant used, and that heparin is to be preferred. A comparison of heparin and ACD-B for maintenance of the activity of arylsulfatase A (EC 3.2.6.1) and hexosaminidase (EC 3.2.1.50) indicates that there is no effect of anticoagulant. However, at 48 h after venipuncture, there is an 80% reduction in the number of heparin-treated samples that are suitable for use in the assay. Those laboratories doing lysosomal enzyme tests on mailed specimens, which are most often greater than 24 h old, should use ACD-B as anticoagulant.
