title: Studies and observations on Lewis grouping of body fluids and stains.
abstract: Leb positive individuals may phenotypically express both Lea and Leb in their secreted body fluids. Therefore, the interpretation of a Le(a + ,b-), non-secretor result is dependent on the absence of Leb. This study emphasises the importance of accurate procedure and biased selection of antisera such that Leb is preferentially detected in comparison with Lea. The relationship of the ABO group to the expression of Le is discussed in conjunction with the selection of samples for testing antisera and inclusion as control standards.
