Abstract:
Leukocytes in "mixed" suspensions can clump together, resulting in cell clusters which are responsible for false positive hot spots in lungs of patients, in the case of abscess localization studies using 111In labeled leukocytes. Addition of extra ACD (acid-citrate-dextrose) in those labeled leukocyte suspensions prevented cell clumping and avoided occurrence of focal radioactivity accumulation in lungs. The acidification did not interfere in leukocyte migration under agar.
