What This Test Measures

The test looks for evidence of exogenous erythropoietin (EPO) or biologically equivalent substances administered to stimulate red blood cell production. This may include synthetic EPO or other erythropoietic agents used to treat anemia in patients with chronic kidney disease.

Why It Matters for Your Care

If you received EPO or similar treatments before your kidneys failed, this information helps doctors assess whether your anemia was managed medically before needing dialysis or a kidney transplant. It may also influence decisions about your long-term care plan.

How the Test Is Performed

This is not a direct measurement of EPO in your blood. Instead, it is a qualitative assessment based on medical records or documentation of prior EPO administration, typically collected during your initial evaluation for ESRD.

What to Expect Before the Test

You may not need to prepare for this test, as it relies on historical medical records rather than a blood draw or other specimen collection. Your healthcare provider will review your chart for prior EPO use.

Clinical interpretation
