Study Notes

Urine Examination Guidelines

The recommended specimen volume for urine examination is 10-15 mL.

Urine Sediment Centrifugation

The recommended relative centrifugal force (RCF) for urine sediment centrifugation is 400-500 × g for 5-10 minutes.

Pediatric Urine Collection

'Wee bags' are used in pediatric patients to collect urine samples, serving as a convenient and non-invasive method for urine collection.

Centrifugation Precautions

It is essential to avoid using the braking mechanism during centrifugation to prevent resuspension of the sediment, which could lead to inaccurate test results.

Urine Sample Handling

Capped tubes or alternative precautions are necessary during urine examination to prevent contamination and spills, ensuring the integrity of the sample.
