Centrifuging the specimen is the most convenient and effective method for concentrating organisms present in cerebrospinal fluid or urine samples before testing. The centrifuge separates the solid materials from the liquid, allowing for a more concentrated sample to be used in the assay. Heat, freeze-thaw cycles, and using larger volumes can damage or dilute the sample, leading to inaccurate results.
