Urinalysis with the cytocentrifuge

Evaluation of the Cytocentrifuge Gram Stain as a Screening Test for Bacteriuria in Specimens From Specific Patient Populations

“…Some have been directed at the detection of pyuria, including microscopic examination for the presence of white blood cells 1 ' 2,3 and the leukocyte esterase test. 4 ' 5 Others have been directed at the detection of bacteriuria, including microscopic examination for the presence of microorganisms, 3,[6][7][8][9][10] the bacterial nitrite test, 4 -5 bioluminescent detection of bacterial adenosine triphosphate, [11][12][13][14] filtration with colorimetric detection of microorganisms, 13 ' [15][16][17] and rapid detection of growth of organisms using various physical or chemical culture characteristics. 11,13 ' 18-20 Microscopic techniques for the detection of microorganisms have included the examination of stained or unstained urine that has been uncentrifuged, centrifuged by conventional techniques, or centrifuged by the slide cytocentrifuge technique.…”

“…11,13 ' 18-20 Microscopic techniques for the detection of microorganisms have included the examination of stained or unstained urine that has been uncentrifuged, centrifuged by conventional techniques, or centrifuged by the slide cytocentrifuge technique. 3 ' [6][7][8][9][10] The Gram stain performed on urine centrifuged by the slide cytocentrifuge technique seems to have several advantages over other available screening tests. It is easier to interpret than other microscopic techniques, 7 and, unlike nonmicroscopic techniques, has the potential to give morphologic information in positive cases.…”
