Pediatric Drug Dosage Calculator

Calculate pediatric drug dosage scores, laboratory indices, and clinical patient metrics with ease.

🩺

Laboratory & Clinical Inputs

Enter serum creatinine, sodium, age, or patient weight.

Serum Creatinine (mg/dL)

Patient Age (Years)

85.4 mL/min/1.73m² Stage 2 (Mildly Decreased)

💡

An eGFR score above 60 is generally considered normal. Scores below 60 persistent over 3 months indicate Chronic Kidney Disease (CKD).

📐

eGFR = 142 × min(Scr/κ, 1)^α × max(Scr/κ, 1)^-1.200 × 0.9938^Age

Applies 2021 CKD-EPI clinical equations endorsed by the National Kidney Foundation (NKF).

📢

For healthcare professional reference only. Clinical decisions require full diagnostic context.

Follow these simple steps for clinical laboratory interpretation:

Gather serum creatinine, blood urea nitrogen (BUN), or electrolyte panel values.

Enter lab values, age, and sex into the input fields above.

Instantly view calculated eGFR value, CKD disease stage, and clinical recommendations.

Glomerular filtration rate is the best overall index of kidney function in health and disease.

Input

Breakdown product of creatine phosphate in muscle.

Output

Filtration rate in mL/min/1.73m² and CKD stage.

What are the 5 stages of Chronic Kidney Disease (CKD)?

Stage 1: eGFR 90+, Stage 2: 60-89, Stage 3a: 45-59, Stage 3b: 30-44, Stage 4: 15-29, Stage 5: <15 (Kidney failure).

Does race affect eGFR calculation?

The 2021 CKD-EPI refitted equation removed race parameters to ensure unbiased health assessments across all populations.
