FSGS Primary vs Secondary Etiology Score

Differentiate primary FSGS (immune-mediated, nephrotic syndrome) from secondary FSGS (adaptive, HIV, drugs, obesity) using clinical, histological, and genetic features.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Differentiate primary FSGS (immune-mediated, nephrotic syndrome) from secondary FSGS (adaptive, HIV, drugs, obesity) using clinical, histological, and genetic features

Each component has a specific meaning:

  • Secondary FSGS (adaptive — The secondary fsgs (adaptive recorded for the scenario being assessed.
  • HIV — The hiv recorded for the scenario being assessed.
  • Drugs — The drugs recorded for the scenario being assessed.
  • Obesity) — The obesity) recorded for the scenario being assessed.

Note: Interpret the fsgs primary vs secondary result against the thresholds and context described above.

How to Use

Enter the secondary FSGS (adaptive, HIV, drugs, obesity) for the scenario you are assessing. Differentiate primary FSGS (immune-mediated, nephrotic syndrome) from secondary FSGS (adaptive, HIV, drugs, obesity) using clinical, histological, and genetic features. Use the fsgs primary vs secondary result to inform your calculation.
