The condition characterized by the presence of protein in urine is proteinuria. Proteinuria is a clinical term that specifically refers to the abnormal excretion of protein in the urine, which can occur due to various underlying health issues, including kidney disease, diabetes, high blood pressure, and other conditions.

Identifying proteinuria is essential as it often signifies that the kidneys are not functioning properly. It can also be an early indicator of kidney disease, making it a crucial sign for further evaluation and management. Regular screening for protein in urine is a common practice in managing patients, especially those at risk for kidney dysfunction.

In contrast, diabetic nephropathy, acute kidney injury, and nephrosclerosis may involve proteinuria as a symptom, but they do not define the condition itself as effectively as the term "proteinuria." These other conditions might be associated with the presence of protein in urine but focus on specific causes or types of kidney damage rather than the symptom alone. Thus, proteinuria succinctly indicates the abnormal presence of protein in the urine, making it the most precise answer.
