Hypovolemia refers to the condition of a reduction in the volume of circulating blood in the body.
The lab values that would suggest hypovolemia because of dehydration are enhanced hematocrit as the concentration of the HCT enhances with the reduction in the fluid. Subsequently, serum osmolarity upsurges and its concentration increases to more than 295 because of decrease in the fluid.
The urine specific gravity also flucuates and there is an increase in concentration of more than 1.030. Ultimately, there is an enhanced level of serum sodium of more than 145 because of hemoconcentration.
