The three-glass method of urine collection is performed to assess _________
Prostate infections
In a urine sample that is being examined microscopically, the best way to differentiate yeast from RBCs is to:
Add a drop of dilute acetic acid to the urine to lyse the RBCs
A low seminal fluid volume of 1.0 mL containing a sperm count of 5 million/mL would indicate:
Infertility
The active accumulation of fluid within body cavities caused by infection, malignancies, or inflammation damaging the vascular wall is known as a(n):
Effusion
What substance besides red blood cells and hemoglobin will react with the blood pad on the reagent test strip?
Myoglobin
The normal healthy reference intervals of CSF total protein is approximately:
20-50 mg/mL
The pigment responsible for normal urine color that present in the highest concentration is:
Urochrome
To determine if a specimen is urine, one should measure the concentrations of:

A positive bilirubin results is noted on the reagent strip used for a routine urinalysis, and bilirubin crystals are noted on the microscopic examination. This would indicate:
Liver disease
Sperm motility that is ranked at a value 3.0 indicates that the sperms are:
Mobile with moderate linear progression
A positive chemical reagent strip test for blood with no red blood cells found in the sediment indicates:
The presence of hemoglobin or myoglobin
A dark, amber-colored random urine sample can be caused by:
Dehydration
The reagent strip method used to detect protein in the urine is based on:

Observations of urine color and clarity should be performed using:
A well-mixed uncentrifuged specimen
The nephritic syndrom frequently occurs as a complication of:
systemic shock
Malabsorption of fats by gastrointestinal system is called
Steatorrhea
The number and type of casts found in urine sediment reflect:
The extent of renal tubular involvement in the disease processes
The hormone responsible for maintenance of sodium balance through its action on the renal tubules is:
Aldosterone
