Q73 – 75: Renal Assessments

*Renal Assessments
Report the renal assessments prior to the start of the preparative regimen / infusion using results measured within 60 days prior to the start of the preparative regimen. If the assessment was performed multiple times, report the closest value to the start of the preparative regimen.

Question 73: Was proteinuria detected? (excluding microalbuminuria)

Proteinuria, also known as albuminuria, is excess protein in the urine and may be a sign of kidney disease. Proteinuria may be assessed by 24-hour urine collection or by a urine dipstick analysis. A value of > 150 mg by 24-hour urine collection or ‘positive’ by a dipstick analysis is indicative of proteinuria.

If proteinuria was assessed within 60 days prior to the start of the preparative regimen / infusion, indicate if proteinuria (excluding microalbuminuria) was detected.

Report Yes if the proteinuria was:

• > 150 mg by 24-hour urine collection or
• ‘Positive’ result by urine dipstick analysis. This also can be reported in EHR as trace, 1+, 2+, 3+, or 4+

Report No if the proteinuria was:

• ≤ 150 mg (by 24-hour urine collection) or
• ‘Negative’ result (by urine dipstick analysis)

If proteinuria was assessed multiple times within 60 days prior to the start of the preparative regimen, report based on the results of the most recent assessment.

If proteinuria was not assessed within 60 days prior to the start of the preparative regimen / infusion, select Not done.

Questions 74-75: 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.”
