Limited and Comprehensive Metabolic Evaluation

Limited Metablic Evaluation

  1. Serum calcium, sodium, potassium, BUN, creatinine, carbon dioxide, chloride

  2. Two random 24 hour urine analyses for volume, creatinine, calcium, oxalate, uric acid, citrate, sodium

Comprehensive Metabolic Evaluation

  1. Two random 24 hour urine analyses for volume, creatinine, calcium, oxalate, uric acid, citrate, sodium, potassium, BUN, phosphate, magnesium

  2. One week of low calcium, low oxalate, low sodium, and low purine diet followed by another 24 hour urine analysis on the restricted diet including serum calcium, sodium, potassium, BUN, creatinine, carbon dioxide, chloride

  3. Calcium load test:

  • 6 AM to 8 AM (2 hour) – Fasting urinary Ca/Cr ratio

  • 8 AM – 1 g oral Ca load (45 mL neocalcium gluconate)

  • 8 AM to 10 AM – urinary Ca/Cr ratio

  • 10 AM to Noon – urinary Ca/Cr ratio
