Calculate 24hour creatinine clearance by 24-hour urine results

Description

Calculates Creatinine Clearance by 24hr urine collection results. CrCL typically overestimates GFR by 10-20 * Creatinine/renal function is in steady state * Creatinine is filtered and not secreted (not true- leads to 10-20 * Complete and well-timed urine collection

Usage

calculate_creatclearance_urine(
  urine_volume,
  creatinine_urine,
  creatinine_serum,
  urine_collection_time = 24,
  bsa_adjust = FALSE,
  height = NULL,
  weight = NULL
)

Arguments

weight	Weight, in kg
age	Age, in years
sex	Sex
creatinine	Serum creatinine, in mg/dL

Value

a numeric vector with eGFR (ml/min/1.73m^2)

Examples

calculate_creatclearance_urine(urine_volume = 1000, creatinine_serum = 1.0, creatinine_urine = 100) # 69.4
calculate_creatclearance_urine(urine_volume = 1000, creatinine_serum = 1.0, creatinine_urine = 100,
                                   bsa_adjust = T) # error- need height, weight
calculate_creatclearance_urine(urine_volume = 1000, creatinine_serum = 1.0, creatinine_urine = 100,
                                   bsa_adjust = T, weight = 70, height = 1.5) # 70.3
