Male: Value of estimated GFRcys (mL/min/1.73m2)
= (104 × Cys - C-1.019 × 0.996Age) - 8
Female: Value of estimated GFRcys (mL/min/1.73m2)
= (104 × Cys - C-1.019 × 0.996Age × 0.929) - 8
We will estimate serum cystatin C using the measurement results based on the international reference substance.
This applies to those over 18 years. (This does not apply to those under 18 years.)
Reporting Requirements
We can report the value of estimated GFRcys only if requested simultaneously with "Cystatin C" (Item Code
No.06199 5No.6199 0).
If any of the following applies to you, we cannot report it:
Only one of "Cystatin C" or "Estimated GFRcys" is requested.
The age and sex are not specified on the request form.
The age is under 18 years.
While the unit is formally "mL/min/1.73m2",
we will report with the reporting unit abbreviated as "mL/min".
