7797-4Rouleaux [Presence] in Blood by Light microscopyActive
Part Description
LP17684-9 Rouleaux
Rouleaux (singular rouleau) are stacks of red blood cells (RBCs) which form because of the unique discoid shape of RBCs in vertebrates. The flat surface of the discoid RBCs provides a large surface area that allows the cells to stick to each other, thus forming rouleaux. Rouleaux occurs when the plasma protein concentration is high, leading to increased erythrocyte sedimentation rate. The presence of rouleaux does not always indicate the presence of a disease. Conditions which cause rouleaux formation include infections, inflammatory and connective tissue disorders, and cancers. It also occurs in diabetes mellitus and is one of the causes leading to microvascular occlusions in diabetic retinopathy.

Mapping Guidance | Regenstrief Help | Most laboratories will report such findings as answers in their RBC morphology term [LOINC: 6742-1]. Others will report each observed finding as a separate variable, such as this one, and assign values of 1+, 2+, 3+. Mapper’s Guide for the Top 2000 plus LOINC Laboratory Observations |
