Share. Albumin is a protein present in the blood. Proteins are normally absent in urine because the kidney cells generally prevent large molecules including proteins, from being excreted. Some proteins may appear in the urine in normal individuals also if blood levels are very high.
Large molecules such as red blood cells and protein, also called albumin, stay in the blood. When your nephrons are damaged, albumin and other proteins leak into your urine. Urine dipstick tests and 24-hour urine collections check for protein in your urine. The presence of protein in your blood is abnormal. Urinary tract infections and diabetes can cause albumin to appear in your urine. Other conditions, such as heavy metal poisoning, bladder cancer, hypertension and systemic lupus erythematosus, can cause protein in the urine as well.
