My recent random urine creatinine is 1.1 mmol/L (with a "low" flag on the report, reference 2.5-20.0 mmol/L) , urine albumin is <5 mg/L.
Report says "Unable to calculate Albumin/Creatinine Ratio as the concentration of the Albumin is less than the lower limit...".

My serum creatinine is 59 umol/L, and eGFR is 110, and I am a 41 years old female.

I don't know what this low urine creatinine means? It seems to be abnormally low, I am so worried... Please help, thank you.

Thank you I appreciate the help, urine albumin was measured separately and urine creat was measured separately and ACR was then calculated from that. the urine albumin was normal and then the urine creat was low. And then he ACR ratio was high. The NP said that the ratio was high due to the Low urine creat and that there was nothing to worry about since it was just a low urine creat and normal urine albumin. What do you think about that

They must all be measured from the same urine specimen. Otherwise they have no value. The degree of urinary dilution is accounted for by the use of a ratio. If the creatinine very very low due to urinary dilution so would the albumin and the ratio unaffected. Sometimes very slender people with less total muscle mass might produce less creatinine (petite women for example). In cases like that, the ratio can be hard to interpret.
