Lithium Cooper Nomogram — Steady-State Level Prediction

Use the Cooper lithium nomogram to predict steady-state lithium levels from a 24-hour test dose level, enabling initial dose selection without waiting for actual steady-state measurements.

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

Use the Cooper lithium nomogram to predict steady-state lithium levels from a 24-hour test dose level, enabling initial dose selection without waiting for actual steady-state measurements

Each component has a specific meaning:

  • 24-hour test dose level — The 24-hour test dose level recorded for the scenario being assessed.
  • Enabling initial dose selection without waiting — The enabling initial dose selection without waiting recorded for the scenario being assessed.

Note: Interpret the lithium cooper nomogram result against the thresholds and context described above.

How to Use

Enter the 24-hour test dose level, enabling initial dose selection without waiting for the scenario you are assessing. Use the Cooper lithium nomogram to predict steady-state lithium levels from a 24-hour test dose level, enabling initial dose selection without waiting for actual steady-state measurements. Use the lithium cooper nomogram result to inform your calculation.
