Welcome to HCM.
Protein in the urine is also called albuminuria
is indicative of abnormally high permeability of the glomerular filtration membrane of the nephron
this can be caused by several things:
-excessively high protein intake
or more seriously...
-excessively high hypertension
You can also get serum creatinine
levels checked and ultrasonography
. For further managment consult a doctor after the reports are available.
