That's a caring question to ask on behalf of your mom. A creatinine level of 234 µmol/L (or about 2.6 mg/dL) is above the normal range, which is typically 0.6–1.3 mg/dL depending on sex and muscle mass. So yes, it is elevated, but it needs to be looked at alongside her full picture. At stage 4, the kidneys are significantly less able to filter waste from the blood, which is why creatinine builds up. Here's what matters most at this stage:
- eGFR (estimated glomerular filtration rate) is the key number doctors use — stage 4 means an eGFR between 15 and 29
- Creatinine alone doesn't tell the whole story; age, sex, and muscle mass all affect the reading
- Trends over time matter — a rising creatinine level can signal faster kidney decline
The most important step is for her nephrologist to review these results in context and adjust her treatment plan if needed. Stage 4 is serious, but there are still meaningful options to help slow progression and protect her quality of life.
