Lambert-Eaton Myasthenic Syndrome Clinical Score

Assesses Lambert-Eaton myasthenic syndrome (LEMS) severity using the QMG-LEMS score, VGCC antibody titer, paraneoplastic SCLC screening priority score, and 3,4-diaminopyridine dosing.

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

Assesses Lambert-Eaton myasthenic syndrome (LEMS) severity using the QMG-LEMS score, VGCC antibody titer, paraneoplastic SCLC screening priority score, and 3,4-diaminopyridine dosing

Each component has a specific meaning:

  • VGCC antibody titer — The vgcc antibody titer recorded for the scenario being assessed.
  • 3 — The 3 recorded for the scenario being assessed.
  • 4-diaminopyridine dosing — The 4-diaminopyridine dosing recorded for the scenario being assessed.

Note: Interpret the lems score result against the thresholds and context described above.

How to Use

Enter the VGCC antibody titer, 3, 4-diaminopyridine dosing for the scenario you are assessing. Assesses Lambert-Eaton myasthenic syndrome (LEMS) severity using the QMG-LEMS score, VGCC antibody titer, paraneoplastic SCLC screening priority score, and 3,4-diaminopyridine dosing. Use the lems score result to inform your calculation.
