===== Diagnosis =====

====  Laboratory Tests ====

Blood tests:

↑ Hematocrit and hemoglobin (hemoconcentration)

↑ Serum sodium ([[hypernatremia]] in some cases)

↑ Blood urea nitrogen (BUN) and creatinine

↑ Serum osmolality

Urine tests:

↑ Urine specific gravity (>1.020)

↑ [[Urine osmolality]]

↓ Urine sodium
----

Blood [[Urea/Creatinine Ratio]] is considered to be an ideal [[biomarker]] of [[dehydration]].
