nameWater deprivation challenge panel - Urine and Serum or Plasma
descriptionA water deprivation test is used to help diagnose diabetes insipidus (DI) and differentiate between different forms of DI and other disorders such as primary polydipsia. In the first phase of the test, the body's response to fluid fasting is measured with a series of timed urine osmolality +/- serum/plasma analyte measurements. The exact analytes that are measured and the timing depends on the protocol used. At the end of the first phase, if the patient has not developed significant dehydration or hyperosmolarity (in which case the testing would be stopped), the second phase of testing is begun. The second phase involves assessing the body's response to a dose of vasopressin and helps differentiate between central and nephrogenic DI.
