Hypernatremia Diagnosis

1. Blood tests:

1) serum sodium concentration: higher than 145mmol / L. Accompanied by many high chlorine levels, and increased the extent of both the general consensus.

2) osmotic pressure of plasma crystals: higher.

3) blood volume: normal or increased red blood cell count, hemoglobin, plasma protein and hematocrit were normal or mildly decreased.

4) red blood cell morphology: narrow red blood cell volume, mean corpuscular hemoglobin concentration increased.

2. Urine test:

1) urinary sodium concentration: increased many, but the stress response in many patients with early decline; in endocrine disorders, and many lower urinary sodium concentration.

2) urinary chlorine concentrations: sodium concentration and urine change.

3) urine osmolality and urine relative density: with the changes in urine sodium concentration in line, the majority of patients discharged because of an increase in sodium chloride, water absorption increased, osmotic pressure and relative density were significantly increased; in endocrine disorders, urinary osmolality and relatively low density.

Cerebrospinal fluid examination: in some patients can be found in the number of red blood cells and protein.
