Crenated RBCs are seen in urine that is:

A. Hyposthenuric

B. Hypersthenuric

C. Highly acidic

D. Highly alkaline

Step 1 of 2

Red blood cells in urine:

• Red blood cells are identified through high power objective in microscope.

• They are reported in average number in 10 high power fields (hpfs).

• In hypersthenuric condition (concentrated) of urine, crenated RBCs appear.

• This is due to loss of water which leads to shrinking of cells.

Crenation:

• Irregular notching in the edge of erythrocytes.

Therefore, Crenated RBCs (Red Blood Cells) are seen in “hypersthenuric” urine. Hence, the correct answer is option.
