What does a serum creatinine of 126 mean when living with one kidney and IgA Nephropathy at CKD stage 3b?
Having a single kidney means it's doing the work of two, so your creatinine levels and how they're interpreted will be a bit different from someone with both kidneys. A creatinine of 126 µmol/L isn't something to panic about on its own — one number rarely tells the whole story. Your care team will look at your creatinine alongside several other markers to get the full picture, including:
- eGFR — estimates how well your kidney is filtering waste
- Proteinuria (urine protein levels) — a key indicator of how active your IgAN is
- UACR (urine albumin-to-creatinine ratio) — helps detect early kidney stress
- Trends over time — whether your numbers are stable, rising, or falling matters more than any single result
Reducing proteinuria is one of the most important treatment goals in IgAN, so if that hasn't been discussed recently, it's worth raising at your next appointment. It's also worth knowing that creatinine can temporarily rise for reasons unrelated to kidney function, such as:
- Eating a lot of cooked meat before the test
- Intense exercise
- Dehydration
- Certain medications
If your levels have been stable over time, that's generally a reassuring sign. If there's been a noticeable rise, your care team may want to repeat the test or adjust your management plan. Don't hesitate to ask them how your latest result compares to your personal baseline — that context matters a lot with one kidney in the mix.
