Donor

Explanation of Condition

Protein present in urine, found either from a urine dipstick test or a Microbiology, Culture & Sensitive (MC&S) test.

Guidance

If protein is detected in the urine, a urine albumin-to-creatinine ratio (ACR) test must be conducted. Proteinuria can be a sign of underlying kidney conditions such as IgA nephropathy or glomerulonephritis, both of which are often undiagnosed. Administration of granulocyte colony-stimulating factor (G-CSF) may worsen these conditions, which is the basis for this precaution.

To be medically cleared for donation, the donor must have a negative urine protein test, or the ACR is <5 mg/mmol ensuring that these kidney diseases are unlikely. If proteinuria is present, the algorithm on the following link must be followed:
