Questions 35 – 36: 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.
If the urine albumin is < 0.1 mg / L, report the urine albumin value as “0 mg / L.”
Questions 37 – 38: 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.
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.”
Questions 39 – 40: Cystatin-C (if multiple, report the most recent tested)
Cystatin-C is a protein in the blood that can be used to evaluate kidney function. If measured, select Known and report the laboratory value. If testing was performed multiple times, report the most recent laboratory value obtained. If the cystatin-C was not measured or if no information is available to determine if the cystatin-C was assessed, report Unknown.
