Effect of centrifugation and microagglutination techniques on Brucella agglutinin titers.
The microagglutination technique without centrifugation was more effective than centrifugation of the standard tube test for increasing Brucella agglutinin titers of specimens with a titer greater than or equal to 160 but was less effective than centrifugation of the standard tube test for specimens with a titer less than 160.
متن کاملCentrifugation techniques and reagent strips in the assessment of microhaematuria.
During a survey for bladder cancer in a healthy male population a surprisingly high incidence of significant microhaematuria was found and no urinary sample was completely free of blood. A study of the sensitivity of the different techniques for assessing microhaematuria seemed necessary. A semiquantitative centrifugation technique, developed for cytological purposes, was found to be the most s...

متن کاملProcessing of semen by density gradient centrifugation selects spermatozoa with longer telomeres for assisted reproduction techniques.
The ends of eukaryotic chromosomes contain specialized chromatin structures called telomeres, the length of which plays a key role in early human embryonic development. Although the effect of sperm preparation techniques on major sperm characteristics, such as concentration, motility and morphology have been previously documented, the possible status of telomere length and its relation with spe...
متن کاملEvaluation of conventional castaneda and lysis centrifugation blood culture techniques for diagnosis of human brucellosis.
We investigated the role of the lysis centrifugation blood culture technique over the conventional Castaneda technique for the diagnosis of human brucellosis. The lysis centrifugation technique has been found to be more sensitive in both acute (20% higher sensitivity; P < 0.00001) and chronic (40% higher sensitivity; P = 0.087) forms of brucellosis. The major advantage of lysis centrifugation w...
