Hello,
Could you please clarify my result, I am a 41 y.o female.

Albumin (Urine) <5mg/L

Creatinine (Urine) 10.5 mmol/L

Albumin/Creatinine
Unable to calculate albumin/creatinine ratio as
the urine concentration of albumin and/or
creatinine is outside the measurable limits.
Decision limit: < 2.0 mg/mmol.

Is it bad that ratio can’t be calculated?

Thank you
A

Immeasurably low albumin is good. The ratio should technically be zero but labs often don’t report it this way. This is of no concern.

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.

If the albumin to creatinine ratio is 12 mg/g then this is normal. If it is 70 mg/g then this is abnormal. You might be mistaking the albumin concentration for 70 (not the ratio). This is why I need to see the exact numbers with units in order to be sure.

the urine albumin was <12mg/g

This is a normal result. More on this here:

hello,
my urine albumin was <12 and my urine creat was low but all together I had urine alb/creat of 75 (not 30), is this concerning? im really worried

Please post an image of the lab sheet with your result so we can see what units were used. Please remove any identifying data first.

eGFR 84
creatinine 25
urine albumin <0.2
albumin/creatinine ratio, random urine—unable to calculate

Just want to make sure I am not overlooking anything. Urine was very foamy 2 1/2 wks ago, considerably less so now.

I am 68 yr-old female.

This is a normal result (unmeasurably low albumin in urine)

A stone in the kidney should not cause what seems to signs of bladder irritation. However, a stone in the bladder could cause such symptoms or else a urinary tract infection (among two common conditions that could present this way - there are others). The fact your symptoms resolved with antibiotics suggests the latter. However, I would suggest you discuss undergoing a cystoscopy with your urologist as visible blood should always be investigated by visualizing the bladder +/- the upper tracts/ureter.

In this context, it is definitely possible that the creatinine rise was a reflection of increased muscle mass. When calculating your eGFR (https://ukidney.com/nephrology-resources/egfr-calculator) it is still within the normal range. It would be interesting to measure your eGFR using a test called cystatin C which is not influenced by muscle mass.
