The use of an amylase-sensitive paper in a screening test for elevated serum amylase levels is described. The paper requires some modification before it can be used as a quantitative amylase assay, but even in its present form it will reliably identify samples with raised amylase levels. In tests with sera received routinely for amylase assay the paper characterised 80% of samples as Normal. Quantitative amylase assay confirmed the results, and thus, even with the present paper, if only the Medium or High sera were sent to the laboratory for full biochemical analysis there would be an 80% decrease in requests.
