NettetOur data suggest that the urine should be centrifuged to remove cell debris and kept at 4 degrees C, rather than at RT, during the collection interval prior to long-term storage in the freezer. Moreover, the addition of 200 mM boric acid or 10 mM NaN3 is highly recommended for the prevention of bacterial overgrowth in the urine. Nettet7. okt. 2024 · To prepare urine sediment for examination, 5 ml of urine should be centrifuged at low speed (1000-1500 rpm for 5 minutes). Do not brake or manually slow down the centrifuge as the resulting turbulence may resuspend the sediment. Remove all but the bottom 0.5 ml of fluid, ...

The Basics of Centrifuge Operation and Maintenance
NettetCentrifuges are typically operated at about 1800–3500 rpm to give a centrifugal force at the wall of the bowl of about 1500–2000 g. The speed differential between the bowl and the scroll is in the range 2–40 rpm but, usually about 10 rpm. Unlike filter pressing, centrifuging is a continuous process. Nettet21. nov. 2016 · For example, if the unspun result showed two hyaline cast/lpf, the spun results should be around 20/lpf. We confirmed what we already knew, that sometimes spinning the specimen actually works against identifying elements if the field is too crowded. And if a sample had very high levels of an element, these would be visible … NettetIts role in the evaluation of proteinuria and hematuria has been discussed in the previous section. A midstream clean-catch technique is adequate in men. 23 When performing urine microscopy, proper care should be exercised in preparing the sample.
