A patient's urine appears red and the blood pad is positive but no red cells are seen microscopically. What is the likely cause?
Answer: Hemoglobinuria or myoglobinuria
Free hemoglobin or myoglobin produces a positive blood pad without intact red cells.
Which protein finding on a reagent strip warrants further investigation for kidney disease?
Answer: Persistent proteinuria
Ongoing protein in the urine can signal glomerular kidney damage.
What is the correct procedure for mixing a urine specimen before microscopic examination?
Answer: Gently swirl the specimen before pouring into a tube
Gently swirling resuspends sediment evenly without destroying fragile elements.
After centrifuging urine for microscopic analysis, which portion is examined?
Answer: The resuspended sediment
The sediment at the bottom is resuspended and examined under the microscope.
A urine ketone result is positive in a fasting patient. What does this most likely reflect?
Answer: Fat metabolism from low carbohydrate availability
When carbohydrates are scarce, the body burns fat, producing ketones.
Which control practice ensures reagent strips are providing accurate results?
Answer: Running quality control specimens regularly
Running known control samples verifies that reagent strips perform correctly.
Squamous epithelial cells abundant in a urine specimen most often indicate what?
Answer: Contamination from the genital area
Many squamous epithelial cells usually reflect contamination during collection.
