What is meant by the terms hematuria and proteinuria?

Hematuria is a term used to indicate the presence of blood in the urine, while proteinuria indicates the presence of abnormal amounts of protein in the urine.

Hematuria is the medical term,  indicating the presence of blood in the urine. This abnormal condition is a result of kidney or urinary tract infections, which require immediate medical attention.

Proteinuria is a medical term explaining the excretion of abnormal amounts of protein in the urine. Normally, the structure of a protein is too large, and cannot pass through the kidneys. Thus, the presence of protein in the urine indicates improper functioning or damaged kidney. Proteinuria serves as a sign of CKD, which results from diabetes, high blood pressure, and inflammatory diseases of the kidneys.
