Answer

Serum lactate elevation is indicative of tissue perfusion and oxygenation resulting in anaerobic metabolism. It may be helpful in cases of severe dehydration or sepsis. The CBC may be helpful in cases in which volume depletion is due to sepsis or hemorrhage. On urinalysis, the urine specific gravity indicates the degree of volume depletion. Urinalysis may also reveal an underlying infectious etiology.
