What could cause albuminuria?

Hi doctor,

I recently blood-tested for kidney function and my results are as follows

1. Urea 6.0 mmol/l 1.7-8.4

2. Creatinine 81 umol/l 62-115

3. eGFR >60 ml/min >60

4. Calcium 2.36 mmol/l 2.12-2.52

5. Inorganic phosphate 1.35 mmol/l 0.78-1.65

6. Uric acid 0.41 mmol/l 0.20-0.42

7. Sodium 140 mmol/l 137-150

8. Potassium 4.4 mmol/l 3.5-5.3

9. Chloride 104 mmol/l 96-108

10. Urine microalbumin 164.0 mg/l

11. Urine creatinine 7.02 mmol/l

12. Microalbumin: creatinine ratio 23.4 mg/mmol

As far as I have noticed, there is no frothing in my urine (other than on occasions when I do not hydrate enough and there are bubbles), no blood in the urine, and my urination frequency has not been abnormal nor have I felt pain anywhere when urinating. But I must say that lately in the past few weeks, I have felt lethargic and tired when I get less than eight hours of sleep.

I am currently not under any medications other than vitamins.

What do my results say? Please help.

Thank you.

Hi doctor, thank you so much for the reply.

Please note that the one report is actually from last year, and the second report is the one for this year, and I attached them for comparison over the one-year period.

What bothers me are the following indicators,

1. Elevated uric acid at 0.41 mmol/l (0.31 last year).

2. Elevated microalbumin: creatinine ratio at 23.4 (0.5 last year).

3. Protein 1+ (negative last year).

Also, my blood pressure is normal and I am not diabetic, although my cholesterol is 5.7 mmol/l.

Thank you.
