Juxtaglomerular Index

Juxtaglomerular (JG) index is one of the important indicators of kidney function. It reflects the kidneys' ability to regulate blood pressure and fluid balance in the body.

The JG index is the ratio of sodium concentration in urine to creatinine concentration in blood. The higher the JG index, the more sodium is excreted from the body, which can lead to dehydration and lower blood pressure.

The JG index can also be used to assess kidney function in patients with chronic kidney disease (CKD). In patients with CKD, the JG index may be reduced, indicating an impaired ability of the kidneys to regulate fluid balance and blood pressure.

To determine the JG index, it is necessary to conduct a urine and blood test, as well as calculate the concentration of sodium and creatinine. You can then calculate the JG index using the formula:

JG index = urinary sodium concentration/plasma creatinine concentration.

A high JG index indicates good kidney function and a balanced fluid balance in the body, while a low JG index indicates impaired renal function and possible fluid loss.

Measuring the JG index is important for the diagnosis and treatment of kidney diseases, as well as for monitoring the effectiveness of treatment in patients with renal failure.
