Question 1

what type of white blood cell is seen MOST frequently in urine sediment with infections of the urinary systems?

Answer 1

neutrophil

Question 2

According to the National Diabetes Data Group recommendations, which of the following statements is TRUE with regards to the following findings?

Fasting glucose = 130 mg/ dl 2-hour post prandial glucose = 210 mg/ dl

Answer 2

The patient may be diagnosed as having diabetes mellitus

*The National Diabetes Data group recommends that the diagnosis of diabetes mellitus be based on two fasting plasma glucose levels of 126 mg per dL (7.0 mmol per L) or higher. Other options for diagnosis include two two-hour postprandial plasma glucose (2hrPPG) readings of 200 mg per dL (11.1 mmol per L) or higher after a glucose load of 75 g or two casual glucose readings of 200 mg per dL or higher. Measurement of the fasting plasma glucose level is the preferred diagnostic test, but any combination of two abnormal test results can be used.

Question 3

A positive leukocyte esterase test indicates the presence in a urine specimen of which of the following?

Answer 3

Granulocytes

*Leukocyte esterase is an enzyme present in most granulocytic white blood cells (WBCs). When the number of granulocytes in the urine increases significantly (more than 0-2 per field), this screening test pad will become positive on the chemical reagent strip.

Question 4

should urine be at room temperature prior to testing with the reagent strip method?

Answer 4

yes because * Urine strip reactivity can increase with increased urine temperature, so the optimum temperature is 22-26o C, or room temperature.
