Which urine test can indicate the level of protein present?

The urine protein test is specifically designed to detect and quantify the amount of protein present in urine. Protein levels in urine can be an important indicator of kidney function and may suggest conditions such as kidney disease, urinary tract infections, or other systemic diseases. In a healthy individual, urine normally contains very low levels of protein, and elevated levels may indicate an issue that requires further evaluation.

The urine pH test assesses the acidity or alkalinity of urine, but it does not provide information about protein levels. The urine glucose test measures the presence of glucose in urine, which can indicate conditions like diabetes, but it too is unrelated to protein assessment. Lastly, the urine specific gravity test evaluates the concentration of solutes in urine, giving insight into kidney concentrating ability but not directly correlating with protein levels. Therefore, the urine protein test is the only option among these that measures protein content specifically.
