What does a urine creatinine level of 537 mg/dL indicate?

Hello,

Welcome to icliniq.com.

Thank you for your query.

I understand your concern and reviewed your reports (attachment removed to protect the patient's identity). Your serum creatinine is normal, which gives an eGFR of 86. eGFR should be more than 60, which is in your case. You were concerned about urine creatinine of 537mg/dL. This carries no significance as it can vary per water and protein intake. If one takes plenty of fluids, urine creatinine levels will decrease. What matters is the serum creatinine level which is normal in your case. Your urine protein level is also normal.

I hope this has helped you. Thank you.

Day-to-day variation of serum creatinine normally is around 10 to 15 percent. So if serum creatinine varies between 0.95 to 1.03, it is okay. However, if serum creatinine is continuously increasing, it is worrisome. You had pain abdomen and dark urine, and I would like to know what happened to that. Do you have symptoms like nausea, vomiting, pain abdomen, and decreased urine output? If you do not have any symptoms and serum creatinine is varying but not continuously increasing, you do not have to worry much. I would also suggest you to avoid painkillers or any unnecessary over-the-counter drugs.

I hope this has helped you. Thank you.

Hello,

Welcome back to icliniq.com.

I reviewed your laboratory reports from ER (attachment removed to protect the patient's identity). Your urine is concentrated, and the increase in serum creatinine looks to be due to dehydration only. The issue in your case is why you are having dehydration and nausea, and back pain. You need to take care of hydration. But if you persist with nausea and back pain, I suggest you visit the specialist.

I hope this has helped you. Thank you.
