Is A Creatinine Level Of 1.07 Indicative Of Acute Renal Failure?
Question: I am a 59 yr old female and lab work showed a creatinine level of 1.07. Now the doctor classified me with acute renal failure. Scared to death but a RN of 35 yrs exp. says not true. Should I be concerned? I am on Lisinopril, Zoloft and Gabapentin. Thanks in advance for your input.
Brief Answer:
that's a little strange...
Detailed Answer:
Hello,
acute renal failure with only 1.07mg/dL is a little strange. Acute renal failure (ARF) requires an acute event that caused impaired urine production by your kidneys. For example producing less than 500mL of urine per day is oliguria and can be a sign of acute renal failure (usually patients with ARF produce much less than 500mL). An increased creatinine level is another sign (and result) of ARF. If your previous creatinine level was 0.4mg/dL for example then 1.07 may signify acute renal failure.
So if you had any of the above then acute renal failure is your diagnosis. If you had none of the above then you probably have some degree of renal malfunction described as chronic renal failure (CRF or CKD- chronic kidney disease). Your body weight is an important parameter to calculate your estimated glomerular filtration rate (eGFR). If your body weight is close to 60Kg then your eGFR should be around 53mL/min which is a stage 3A CKD.
Sometimes dehydration may produce transiently abnormal results in urea and creatinine. Rehydrating corrects them completely (most of the times). If you'd like to upload your tests it would help me to find out more.
Kind Regards!

Thank you; I've uploaded the lab work for you.
Brief Answer:
can't distinguish between ARF and CRF (CKD) based on a single test
Detailed Answer:
Thanks for the additional info!
My opinion is the same as before. No doctor can say whether this is CKD or ARF. ARF would require either too much urine (many liters per day) or too little urine (usually 100-200mL per day). Certain CKD features like calcium disorders are lacking.
Although I can't say for sure, CKD seems more likely in your case. I would have ordered repeat testing to make sure that creatinine values do not rise, a urinary tract ultrasound scan to make sure there is no obstruction and a urinalysis (!) to detect potential signs of renal damage. Avoiding any unnecessary drug may prevent further damage. NSAIDs (non-steroidal anti-inflammatory drugs) in particular are very toxic to the kidneys. Dehydration should also be avoided.
I hope you find my comments helpful!
You can contact me again, if you'd like any clarification or further information.
