Edema Inspection

Edema caused by different reasons according to laboratory tests carried out are not the same need. Common clinical edema often due to some important system caused by disease or organ, so in addition to edema, general laboratory examination, also need to be checked for their primary disease, to determine prognosis and estimation edema edema. For patients with generalized edema should generally be considered for the following laboratory tests.

1. Measurement of two plasma protein albumin

Such as plasma protein is less than 55 g / l or albumin less than 23 g / l, expressed plasma colloid osmotic pressure. Which is particularly important to reduce albumin. Plasma protein and albumin reduce common in cirrhosis, nephrotic syndrome and malnutrition.

2. urinalysis and renal function tests

There are systemic whether there is protein, red blood cells and casts, etc. should be checked within edema urine. If no proteinuria and edema probably not caused by heart or kidney disease. Patients with heart failure often have mild or moderate proteinuria, and persistent severe proteinuria characterized by nephrotic syndrome. Persistent proteinuria, red blood cells and casts in urine increased significantly associated with renal dysfunction often prompted edema kidney disease; although patients with heart failure may also have the above performance, but changing urinalysis and renal function in degree lighter than normal. And edema of renal function tests, often used a peptide known as phenol methyl phenol red test, urine concentration and dilution test, urea clarification tests aimed at measuring renal excretory function.

3. Determination of red blood cell count and hemoglobin content

Such as red blood cell count and hemoglobin content was significantly reduced edema should consider this possibility and anemia.

The daily intake and excretion of water and sodium computing

Calculate the daily water and sodium intake and excretion were measured in plasma sodium content when necessary, help to understand the body of water and salt retention situation.
