Exercise 6

Specimens that contain hemoglobin can be visually distinguished from those that contain RBCs because:

A. Hemoglobin produces a clear, yellow specimen

B. Hemoglobin produces a cloudy pink specimen

C. RBCs produce a cloudy red specimen

D. RBCs produce a clear red specimen

Step 1 of 2

Abnormal Urine Color (Red):

The occurrence of blood causes red color to urine.

• The blood color varies between pink to brown depends on pH of urine, quantity of blood, and period of blood contact with urine.

• Other than RBC (Red Blood Cells), myoglobin and hemoglobin causes red urine.

• When the urine looks red and cloudy, then RBC existing in it.

• Presence of hemoglobin produces clear, yellow color urine.

• Comparing the cloudiness and clearness, specimen containing hemoglobin is easily differentiated from specimen containing RBC.

Therefore, in a specimen, hemoglobin is notable from RBC because “hemoglobin produces a clear, yellow specimen”. Hence, the correct answer is option.
