F/36yrs. low bp, cmpanel/glucose/insulin normal. creatinine,urine=145.7mg/dl, microalbumin,urine 59.3ug/ml(hi)&microalb/creat ratio 40.7 (hi). cause?

Microalbuminuria: The causes of microalbuminuria include diabetes, hypertension, latent glomerulonephritis, inactive glomerulonephritis, IgA glomerulonephritis, toxic effects from NSAIDs or other meds, a latent allergic disease. A microalbumin/creatinine ratio of 40 is barely elevated (normal less than 30) -- so repeat it a few times.

Can be 'normal' if: sample given within 24 hrs. after exercise normal glucose/ insulin doesn't rule out diabetes; check Hga1c need urinalysis to look at sediment see MD
