Urine is a by-product of the body’s metabolism and therefore it is a product of excretion system. What this means is that blood and protein in urine is an abnormal condition that needs medical attention. Generally, blood and proteins, when found in the urine indicate a problem of the filtration and function of the kidney. Blood alone may indicate an infection or disease of the genitourinary tract The proteins are too big to fit through the filtration membranes of the kidney and when they are found in urine, it means that the kidneys’ filtering system is damaged.
Damage on the filter system can open the filtration holes large enough to allow the proteins to pass through. The damage of the filtration system of the kidney may occur due to an infection. The engorged while blood cells may get trapped on the filters and die there and the digestive enzymes they release may damage the filters. For the case of blood, it should never go through the kidney’s filter system even when they are damaged.
Therefore, when you notice the presence of red blood cells in urine, it means that there is bleeding in the urinary tract system. Kidney stones, cancerous growth, enlarged prostate glands and also infection of the bladder are common causes of blood in urine. White blood cells can also occur when there is an infection and the body responds by sending the white blood cells to fight the infection. This leads to leakage of the cells to the urine.
The presence of protein and blood may change the color of the urine and it will appear deep yellow. The change in color of the urine may also arise due to intake of drugs and food. When the color of the urine is brown, this may indicate the presence of broken down hemoglobin and this is a protein that promotes the transfer of oxygen in the red blood cells. The urine can also appear brown because of red blood cells.
Muscle protein known as myoglobin may also lead to brown urine. The blood and urine of certain individual who have impaired kidney function experience increased amount of protein known as Neutrophil Gelatinase-Associated Lipocalin (NGAL). These small proteins are released from injured tubular cells, which are responsible for proper functioning of the kidneys. Studies show that people with high levels of NGAL are likely to experience worsening of the kidney function within one year when it is compared to counterparts with lower levels of this protein.
The treatment of blood and protein in urine depends on the underlying cause of the presence of these elements, which virtually should not be present in urine under normal circumstances. Protein and blood are not by-products and therefore, they are needed in the body and should not be excreted by the kidney. When you have signs of presence of protein and blood in urine, you need to consult a doctor for proper medical examination. The blood and protein examinations may be carried out separately as blood could indicate an infection of the kidneys, urinary tract, the bladder and ureters, while protein could indicate damage of the kidney filters.
