Study Notes
- Hypoalbuminemia can be caused by dilution, redistribution, decreased synthesis, increased loss, or increased catabolism.
- Hyperalbuminemia can be caused by dehydration or be an artifact.
- Decreased albumin can lead to extravasation of fluids and peripheral edema.
- Fluid retention due to renal impairment can cause peri-orbital edema.
- Proteinuria is a condition where urine contains an abnormal amount of protein.
- Normally, less than 100 mg/day of protein and less than 30 mg/day of albumin is lost in urine.
- Proteinuria is most often caused by kidney disease due to glomerular defects or defective renal tubular reabsorption.
- Proteinuria is most often detected by screening with reagent strip dipstick.
- Proteinuria is the presence of a significant amount of protein (>300mg/24 hours), mostly albumin.
- Proteinuria can occur when the filters of the kidney, called glomeruli, are damaged.
