Lithium Toxicity Risk Assessment by Serum Level

Assess lithium toxicity risk based on serum level and clinical signs, classifying mild (1.5-2.0 mEq/L), moderate (2.0-2.5 mEq/L), and severe (>2.5 mEq/L) toxicity requiring emergency management.

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

Assess lithium toxicity risk based on serum level and clinical signs, classifying mild (1.5-2.0 mEq/L), moderate (2.0-2.5 mEq/L), and severe (>2.5 mEq/L) toxicity requiring emergency management

Each component has a specific meaning:

  • Serum level — The serum level recorded for the scenario being assessed.
  • Clinical signs — The clinical signs recorded for the scenario being assessed.
  • Classifying mild (1 — The classifying mild (1 recorded for the scenario being assessed.

Note: Interpret the lithium toxicity risk result against the thresholds and context described above.

How to Use

Enter the serum level, clinical signs, classifying mild (1 for the scenario you are assessing. Assess lithium toxicity risk based on serum level and clinical signs, classifying mild (1.5-2.0 mEq/L), moderate (2.0-2.5 mEq/L), and severe (>2.5 mEq/L) toxicity requiring emergency management. Use the lithium toxicity risk result to inform your calculation.
