KFT is a diagnostic test to assess the functioning and health of kidneys. (Kidney Function Test) The kidneys play a crucial role in blood filtration and excreting out waste from the body. Urea is the nitrogenous wastes that must be excreted out from the human body. Uric acid is generated mainly in birds as the toxic substances that are released during various metabolic processes inside the body. These toxins need to be excreted out of the body in a timely manner. If the kidneys are damaged, or some hormonal factors are hampering the functioning of kidneys, it will result in incomplete excretion or incomplete filtering of the blood. The improper functioning of kidneys can be detected in the KFT report.
What is KFT?
KFT is abbreviated as kidney function test. It is also known as the renal function test. KFT is a diagnostic test to check the functioning of the kidneys. The procedure involves a blood test and a urine test to evaluate the number of toxins present in the blood and the substances released in urine. At times, blood is also released in the urine, which shows a serious problem in the kidneys.
A kidney function test evaluates the amount of the following substances in the body;
- 1. Creatinine
- 2. Urea
- 3. Uric acid
- 4. Serum osmolarity
- 5. Extracellular fluid volume
- 6. Electrolyte concentrations
- 7. Level of hormones (erythropoietin, renin, and 1,25 dihydroxy vitamin D).

Why KFT?
Kidney function is assessed to check and manage the conditions of kidney patients. It is an important test to detect kidney tissue damage or the type of kidney disease or kidney infections hampering renal function.
- 1. To detect the types of kidney diseases
- 2. Kidney infections
- 3. Kidney cancer (benign or malignant)
- 4. Genetic cause (Polycystic Kidney Disease)
- 5. Autoimmune disorders (lupus nephritis)
What is Autoimmune Kidney Disease?
Autoimmune diseases are those diseases in which the body’s immune system attacks its own cells. In the case of autoimmune kidney disease, the immune system targets and attacks its own kidney cells. One of the common autoimmune kidney diseases is lupus nephritis. Lupus nephritis is the condition in which lupus autoantibodies affect the filtering unit of kidneys.
Lupus nephritis
The name of the disease (lupus nephritis) is derived from nephrons (functional units of the kidney) that are involved in filtering out the body. Damage to kidneys:
- 1. Kidney inflammation
- 2. Blood in urine
- 3. High protein in urine
- 4. Irregularities in kidney functions
- 5. High blood pressure
- 6. Kidney failure
