Lab Values With Dehydration. In severe dehydration cases laboratory testing is often ordered to identify acid base and electrolyte imbalances and to evaluate general health status and kidney function. Fluid was given to16 out of 43 patients 37 withserumureaconcentrations514 3mmol l 29 49 59 with bicarbonate concentrations. Total serum protein and hematocrit provide a rough estimate of reduction in circulating blood volume but calculation from these data will usu. Lab values in isotonic dehydration isotonic dehydration will show normal serum laboratory values including normal osmolality of 285 295 mosm kg and normal serum sodium of 135 145 mmol l.

In an otherwise healthy child with acute dehydration known to be due to diarrhea or vomiting the amount of deficit can best be estimated by accurate weight. Total serum protein and hematocrit provide a rough estimate of reduction in circulating blood volume but calculation from these data will usu. They often tell the story of dehydration long before physical symptoms manifest. This is attributed to the fact that dehydration can cause blood volume to decrease leading to a drop in blood pressure and blood flow. Laboratory parameters were less important in helping reach a decision on uid replacement.
Urine volume will be decreased with low fractional sodium excretion and increased specific gravity.
In an otherwise healthy child with acute dehydration known to be due to diarrhea or vomiting the amount of deficit can best be estimated by accurate weight. In cases of severe dehydration laboratory testing is frequently ordered to identify electrolyte and acid base imbalances to evaluate kidney function and general health status. Look at the sodium level. Laboratory parameters were less important in helping reach a decision on uid replacement. Yes it is possible for dehydration to skew the results of a cholesterol test. Reading lab work to determine if a patient is dehydrated takes some experience.
