The preservation of the bodys water and electrolyte balance as well as the disposal of waste products are crucial functions of the kidneys. A series of blood tests known as the Kidney Function Test (KFT) are used to assess how effectively the kidneys are functioning. In addition to KFT, it measures electrolyte levels to look for water or a pH imbalance in the body. It is suggested if you experience kidney-related symptoms including eye puffiness, red or frothy urine, frequent urination urges, etc. This examination is typically included in regular medical exams. It aids in both the diagnosis of kidney-related problems and the monitoring of renal disease treatment effectiveness.
