B. RBCs

C. WBCs

D. Bacteria

Step 1 of 2

Sediment examination of urine:

• Sediment volume placed in microscope slide should be constant for every specimen.

• When glass slide method is used, suggested volume is 0.02 milliLiter (20 (micro Liter)) and it is covered by mm (millimeter) glass cover slip.

• When specimen is overflowed outside of cover slip, it results in loss of casts present in it.

Therefore, “casts” might be missed when the cover slip is overflowed in cover-slip and glass slide method. Hence, the correct answer is option.
