Urinalysis and Microscopic Examination of Urine Sediment

These flashcards cover key terms and concepts related to urinalysis and microscopic examination of urine sediment from the lecture notes.

Fine Adjustment

A microscope feature used to sharpen the focus for clear representation of sediment constituents.

Low-Power Field (lpf)

A measurement unit indicating the average number of elements observed per low-power field during microscopic examination.

High-Power Field (hpf)

A measurement unit indicating the average number of elements observed per high-power field during microscopic examination.

Semiquantitative Reporting

A method of reporting results in descriptive terms such as rare, few, moderate, many, or using a scale (1+, 2+, 3+, 4+).

Concentration Factor

A numerical value used to standardize the results based on the volume of sediment examined.

Addis Count

A historical method for quantifying formed elements in urine using a hemocytometer, developed in 1926.

Microscopic Examination Correlation

The process of ensuring that microscopic results align with physical and chemical findings to verify accuracy.

Technical Errors

Mistakes that can occur in laboratory processes that may affect the results of urine analysis.

Artifacts

Unwanted structures or substances in the urine specimen that may interfere with the microscopic examination.

Standardized Procedures

Documented methods that must be followed by laboratory personnel to ensure consistency in testing.
