Good afternoon doctors. my microalbuminuria was 22 last august, 2021. yesterday it went up to 27. from what i see, below 30 is normal, but is this increase in only 7 months concerning and worrisome?

That change is common, you should only concern if the number is PERSISTENTLY above 30. A higher protein intake on the previous day or a mild increase in mean arterial pressure at the time of urine collection can cause that change or most of the time it is just the laboratory variation.

Not necessarily as this amount could be a normal variation. Have another one in six months. Good luck
