Which urine dipstick reagent pad detects glucose via the glucose oxidase reaction?
Answer: Glucose pad
The glucose pad uses glucose oxidase to catalyze glucose to gluconic acid and hydrogen peroxide, which then reacts with a chromogen to produce a color change.
A urine specific gravity of 1.035 most likely indicates:
Answer: Concentrated urine
A specific gravity of 1.035 is above the normal range (1.003–1.030) and indicates highly concentrated urine, often seen in dehydration.
Which formed element in urine sediment is pathognomonic for glomerulonephritis?
Answer: RBC casts
RBC (red blood cell) casts in urine sediment are characteristic of glomerular inflammation or glomerulonephritis.
Bence Jones proteins in urine are best detected by:
Answer: Heat precipitation at 60°C then redissolving at 100°C
Bence Jones proteins precipitate at 40–60°C and redissolve when heated to near boiling, distinguishing them from albumin.
Which urine color is most associated with myoglobinuria?
Answer: Red-brown
Myoglobin released from damaged muscle gives urine a red-brown or cola-colored appearance and tests positive on the dipstick blood pad.
Trichomonas vaginalis in a urine sediment is best identified by:
Answer: Its pear shape and flagella on wet preparation
Trichomonas vaginalis is recognized as a motile, pear-shaped organism with anterior flagella visible on a fresh wet preparation of urine sediment.
