Dialysis-related laboratory measurement (qualitative assessment of dialysis adequacy or specific analyte monitoring)

What This Test Measures

Dialysis removes toxins and excess fluids from your blood, but some waste products or markers may still be present. This test may measure specific substances (like urea, creatinine, or other metabolites) to check if dialysis is effectively supporting your health. Some tests may also look at electrolytes or other indicators of balance.

Why It’s Done

Your healthcare team may order this test if you have kidney disease requiring dialysis to monitor how well your treatment is working. It helps prevent complications like fluid overload, electrolyte imbalances, or remaining waste buildup.

Common Uses in Dialysis Care

This test can be used to confirm dialysis is removing enough waste, track changes over time, or guide adjustments to your treatment plan. Some versions may focus on specific markers like blood urea nitrogen (BUN) or creatinine levels, depending on the lab’s approach.

What to Expect Before the Test

You may receive this test during or after a dialysis session, depending on the type. Blood is typically drawn from your arm or access site (like a fistula or catheter). If urine is involved, you may be asked to collect a sample at home or during a visit.
