The Sia Euglobulin Precipitation Test Revisited

摘要

The Sia test (Sia euglobulin precipitation test) was first described more than three-quarters of a century ago for evaluation of the euglobulin fraction in certain infectious diseases (1). In this test, serum is diluted with water so that the ionic strength of the serum is decreased, resulting in the precipitation of euglobulins and macroglobulin (2). Later, positivity of the Sia …
