Lab Values That Indicate Dehydration. Higher volumes of bun and creatinine indicate that the kidneys are not working properly. If you re dehydrated you re also likely to have low blood pressure especially when moving from a lying to a standing position a faster than normal heart rate and reduced blood flow to your extremities. Sodium potassium and blood urea nitrogen bun are all indicators of a patient s hydration status. Look at the sodium level.
Higher volumes of bun and creatinine indicate that the kidneys are not working properly. Both tests measure the amount of waste product in the blood. Dehydration is known to reduce blood flow to the kidneys and elevate creatinine and bun levels in the blood. The significant differences observed before and after dehydration were maintained for the next 60 minutes. Due to the lack of a reliable way of clinically measuring dehydration laboratory tests are usually used to improve the accuracy of clinical assessment of dehydration in children the purpose of this study was to compare the relationship between clinical and laboratory parameters in the assessment of dehydration and to evaluate the improvement of those parameters over time. 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.
If organ dysfunction and or imbalances are discovered then serial testing might be conducted to monitor an individual over time as well as how they respond to treatment.
They often tell the story of dehydration long before physical symptoms manifest. To help confirm the diagnosis and pinpoint the degree of dehydration you may have other tests such as. The significant differences observed before and after dehydration were maintained for the next 60 minutes. Both tests measure the amount of waste product in the blood. If imbalances and or organ dysfunction are found then serial testing may be performed to monitor the person over time and their response to treatment. Total serum protein and hematocrit provide a rough estimate of reduction in circulating blood volume but calculation from these data will usually underestimate the deficit.
