A method, and associated kit, for assaying the activity of lysosomal enzymes present in dried bodily fluids and cell tissue samples, such as α-L-iduronidase, β-D-galactosidase, β-D-glucosidase, chitotriosidase, total α-D-galactosidase and α-D-galactosidase A, hexosaminidase A and B, α-D-mannosidase, β-D-mannosidase, α-L-fucosidase, N-acetyl-α-galactosaminidase, arylsulfatases, sphingomyelinase, β-galactocerebrosidase, iduronate-2-sulfatase and β-D-glucuronidase. The method includes: (a) combining with a dried bodily fluid or cell tissue sample containing at least one type of lysosomal enzyme: (1) an eluent, (2) an incubation buffer and (3) a substrate or substrates capable of reacting with the assayed lysosomal enzymes and producing their corresponding enzyme product or products, (b) allowing the dried bodily fluid or cell tissue sample to react with the eluent, incubation buffer and substrate or substrates for an adequate time and temperature, and (c) applying measuring means to the enzyme product to determine the activities of the lysosomal enzymes present.
