- white cells with fat inclusions
- degenerated tubular epithelium containing fat
- globules of free fat
- fat-filled casts
- fertilized ova
- If a precipitate of amorphous phosphates obscures the sediment in urine, the precipitate can be removed by adding:
- dilute sodium hydroxide
- ethanol
- concentrated nitric acid
- dilute acetic acid
- acetone
- The action of the Clinitest tablet is based on:
- the reduction of ferric ions
- the reduction of cupric ions
- an enzyme specific for glucose
- an enzyme specific for reducing sugars
- the reaction of glucose with o-toluidine
- Which of the following analytes react(s) with para-dimethylaminobenzaldehyde to form a cherry red compound?
- creatinine
- ketones
- protein
- glucose
- urobilinogin
- A healthy individual may occasionally have __ RBC/high powered field in a random urine specimen:
- zero
- 2-4
- 8-10
- 15-25
- 25-30
- The specific gravity of normal urine is:
- 1.000 - 1.005
- 1.005 - 1.020
- 1.005 - 1.030
- 1.010 - 1.040
- 1.05 - 1.07
- The nitroprusside test used on dipsticks detects:
- beta-hydroxybutyric acid
- creatinine
- glucose
- acetoacetic acid
- blood
- The protein test on the Multistix is based on the principle that:
- protein changes the pH of the test area and therefore the color of the indicator
- proteins are zwitterions and change the charge on the buffer
- the buffer changes the charge on the proteins causing them to form colored complexes
- at a fixed pH certain indicators will have one color in the presence of protein and another in the absence of protein
- proteins precipitate at high pH
