Kidney Function Test
The kidney is an important organ for all living things, whether human or animal. The main function of the kidneys is to get rid of toxic waste found in our blood through urine.
Kidneys need to function properly to ensure perfect body health. Diseases such as diabetes, high blood pressure can damage the kidneys if not treated by a doctor. Taking medicine including traditional medicine without doctor's advice is also a cause of kidney failure. Food contamination such as pesticides can also lead to kidney damage.
In general, most of the processes that occur in the body will produce toxic waste products such as urea, creatinine, uric acid and ketone bodies.
Failure of the kidneys to function properly will cause severe health problems. Therefore, serious kidney patients need to undergo dialysis to clean the blood from harmful toxic substances. A dialysis machine works as a kidney replacement.
Blood carrying toxic substances flows through the renal arteries into the kidneys. In the kidneys, the blood will undergo a filtration process. All toxic substances will be filtered and eliminated through urine. Blood that has been detoxified will leave the kidney through the renal vein and circulate back to the rest of the body. This process takes place throughout our lives.
Doctors can find out the status of the kidneys by carrying out procedures such as laboratory tests and X-ray tests. Laboratory tests are usually done through blood tests and urine tests.
Among the blood tests involved are urea and creatinine level tests. Urea is a waste product of the body as a result of protein metabolism. Creatinine is a waste product of the body as a result of muscle protein metabolism. Urea and creatinine are usually removed by the kidneys through urine.
The concentration of urea and creatinine in the blood that exceeds the normal level is an indication of real kidney failure.
The estimated glomerular filtration rate (e-GFR) test is a test to estimate the renal glomerular filtration rate. Kidney function is normal when our e-GFR is between 90 - 120 ml/minute. If our e-GFR is less than 60 ml/minute, there is a possibility of kidney damage.
The presence of red blood cells and protein in the urine may also be a sign of kidney function problems.
Some types of metabolic and medicinal waste products are toxic if excessive in the blood. Since the kidney functions as an organ that removes toxic substances from the body, kidney tests are often performed if the doctor wants to start a treatment to find out the effects of drugs consumed by the patient that can cause kidney damage.
Excessive intake of supplements such as multi-vitamins, mineral salts or traditional medicine may cause kidney failure. Therefore, we need to ask a doctor for advice before starting to take food supplements or traditional medicine continuously.
