Reagent strips soaked in your urine sample made it possible to detect the presence of protein, most often during a systematic examination. To confirm and interpret this proteinuria, your doctor must have recourse to the analysis of the dosage of proteins, in particular albumin, emitted in twenty-four hours in your urine. Albumin is a protein in the blood. Its daily emission, or albuminuria, in the urine is carried out in small quantities: less than 150 mg, it is said to be physiological and therefore not pathological.
- The proteinuria which accompanies a febrile affection and disappears at the same time as the fever;
- The proteinuria which accompanies a urinary tract infection and disappears with its healing;
- Proteinuria caused by efforts ;
- Proteinuria which only appears in a standing position (on the other hand, it is absent from the urine collected after a night of extended rest).
The last two cases require regular monitoring in order to detect a possible transition to permanent proteinuria.
- Glomerulonephritis: proteinuria, less than 3g / day, is accompanied by hematuria and high blood pressure;
- Nephrotic syndrome: proteinuria, greater than 3 g / day, is composed almost exclusively of albumin and accompanied by edema.
Many diseases cause proteinuria; let us quote: diabetes, myelone ...
During pregnancy, albuminuria associated with arterial hypertension and edema evokes pregnancy toxemia.
