I made a kidney functions test and my albumin micral test showes 26.1 mg/l the and the normal range in the lab less than 15 is that a problem?

Probably not: Why was this done in the first place? I wouldn't raise an eyebrow with any urine protein below 8 mg/dL = 80 mg/L. If you have no other signs of ill-health, this is most often due to orthostatic proteinuria -- some folks get it just from standing up. Since you're within what I think is normal range, even checking for that is probably unnecessary.
