Microscopic Examination of Urine

Flashcards covering key concepts from the microscopic examination of urine lecture.

Microscopic Examination

The third part of routine urinalysis focused on detecting and identifying insoluble materials in urine.

Urinary Sediment

Insulin solubles like red blood cells, white blood cells, and epithelial cells present in urine.

Centrifugation

A process used in urinalysis to separate sediment from urine by spinning samples at high speed.

Macroscopic Screening

Initial examination of urine specimens to determine if microscopic analysis is needed based on specific criteria.

Leakocyte Esterase

An enzyme that indicates the presence of white blood cells in urine, suggesting infection.

Clinical and Laboratory Standards Institute (CLSI)

Organization that provides guidelines and recommendations for laboratory practices, including urinalysis.

Concentration Factor

Ratio of the volume of urine centrifuged to the volume of sediment, critical for quantitating elements.

Clean-Catch Midstream Specimen

Urine specimen collection method minimizing external contamination.

Casts

Cylindrical structures formed from proteins and cells found in urine sediment, indicating kidney health.

Sediment Resuspension

The process of mixing sediment back into the urine sample to ensure even distribution for microscopic analysis.
