Under normal circumstances, urine does not contain:

1. Red blood cells: The presence of red blood cells in the urine, a condition known as hematuria, can be a sign of conditions such as urinary tract infections, kidney disease, or bladder or kidney stones.

2. White blood cells: Similarly, white blood cells in the urine can indicate an infection or other medical condition. This is known as pyuria.

However, urine typically does contain:

1. Glucose: While glucose is usually present in the urine, high levels can be a sign of diabetes or other conditions.

2. Sodium (Na+): Sodium is one of the many electrolytes that are typically present in urine. The kidneys regulate the body's sodium level by controlling the amount excreted in the urine.
