Checkzyme, an extract from the seeds of Glycine soja or max, agglutinates sialic acid-depleted red cells. Consequently, red cells which have been appropriately treated with a proteolytic enzyme will be agglutinated by the extract. Checkzyme is, therefore, an indispensable serology tool for determining successful proteolytic enzyme pre-treatment of red cells. All negative results from the enzyme phase of any tests involving enzyme pre-treatment (e.g. the crossmatch test), should have one drop of Checkzyme added and a positive result obtained. A negative result indicates inadequate enzyme pre-treatment; hence, the test must be repeated. With the exception of red cells from individuals of the phenotypes Mk and En(a-), and red cells from patients who are T-exposed, all red cells will give a negative reaction with Checkzyme, prior to treatment with a proteolytic enzyme.
