Understanding Sehgal Index: Normal vs Optimal Ranges

?What is Sehgal Index?

The Sehgal Index is a composite scoring system used to assess the degree of interstitial fibrosis and tubular atrophy in kidney biopsy samples, helping to stratify chronic kidney disease severity. It combines histological findings to predict renal prognosis and progression risk. The index is primarily used in nephropathology to quantify structural damage in the kidneys.

!Why It Matters

An elevated Sehgal Index may suggest greater degrees of irreversible kidney damage and could indicate a higher risk of progression to end-stage renal disease. This scoring helps clinicians identify patients who require more aggressive intervention and closer monitoring. It serves as a prognostic tool complementing other clinical and laboratory markers of kidney function.

Reference Ranges

Lab normal ranges may vary between laboratories. Optimal and longevity targets are based on research literature and should be interpreted with your physician.

Symptoms of Imbalance

• Progressive proteinuria or albuminuria
• Declining estimated glomerular filtration rate (eGFR)
• Persistent hypertension
• Edema or fluid retention
• Fatigue and weakness from declining renal function

How to Improve Your Levels

• 1Maintain strict blood pressure control (target <120 mmHg systolic)
• 2Reduce dietary sodium intake to <2,300 mg per day
• 3Limit protein intake as advised by a nephrologist
• 4Manage underlying conditions such as diabetes and hypertension
• 5Avoid nephrotoxic medications and substances
• 6Regular follow-up with renal specialists for disease monitoring

When to Test

Kidney biopsy with Sehgal Index scoring is typically performed when there is unexplained proteinuria, declining kidney function, or suspected primary or secondary glomerulonephritis to guide treatment decisions and prognosis assessment.
