Q47-51: Renal Assessments

Questions 47 – 48: Urine albumin

Indicate whether urine albumin was measured prior to the start of the preparative regimen / infusion. If measured, select Known and report the laboratory value and unit of measure documented on the laboratory report. If urine albumin was assessed on multiple dates, report the most recent results. If urine albumin was not measured or if no information is available to determine if urine albumin was measured, report Unknown and go to question 49.

If the urine albumin is < 0.1 mg / L, report the urine albumin value as “0 mg / L.”

Question 49: Serum creatinine

Indicate the most recent serum creatinine value prior to the start of the preparative regimen / infusion. Report the laboratory value and unit of measure documented on the laboratory report.

*Glomerular Filtration Rate (GFR):
Questions 50 – 51 are only enabled for adult recipients (> 18 years of age). The GFR is collected for pediatric recipients (≤ 18 years of age) on the Pre-TED (2400) Form.

Questions 50 – 51: Glomerular Filtration Rate (GFR)

The glomerular filtration rate (GFR) estimates how much blood passes through the glomeruli each minute and is used to check how well the kidneys are working. Indicate whether the GFR was measured prior to the start of the preparative regimen / infusion. If measured, select Known and report the laboratory value and unit of measure documented on the laboratory report. If testing was performed multiple times, report the most recent laboratory value obtained. If the GFR was not measured or if no information is available to determine if the GFR was assessed, report Unknown and go to question 52.

GFR may be reported to the CIBMTR as “actual” or “calculated.” If your center’s laboratory does not calculate the actual GFR value, use the Cockcroft-Gault equation (see equation below) to determine the calculated value.

Cockcroft-Gault Equation

GFR = ((140-age)x Wt)/(72 x Cr)

• GFR_cg = Glomerular Filtration Rate (Cockcroft) (mL / min)
• Age = Patient Age (years)
• Sex = Gender (Male)
  • If female, multiply result by 0.85
• Wt = Body Weight (kg)
• Cr = Creatinine (S, mg / dL)

If the laboratory report indicates the GFR as a range, report the average. Example, if the laboratory report indicates GFR is 80 – 120, report “100.”

For values expressed as g “> X,” report the value as “X+1.” Example, if the laboratory report indicates the GFR is greater than 120, report “121.”

If the laboratory report indicates the GFR “< X,” report the value as “X-1.” Example, if f the GFR is reported as < 80, report “79.”
