What lab value is consistent with diabetes insipidus

Normal values of vasopressin can range from 1 to 5 pg / mL (0.9 to 4.6 pol / L). If you are below 1 you can indicate diabetes insipidus

Explanation:

For the diagnosis what I can see is the amount of sugar in the urine to rule out diabetes mellitus. For diabetes insipidus, a blood test will show abnormal concentrations of many electrolytes, such as sodium.  

A water deprivation test is also performed. With this test you can confirm the diagnosis and determine the cause of diabetes insipidus.

 The test is to stop drinking fluids for some time so that your doctor can measure changes in your body weight, the production of urine, the concentration of your urine and blood when you retain liquids. It must be done under medical supervision  

The doctor may also order an vasopressin blood test or administer synthetic vasopressine during the test.

Normal values of vasopressin can range from 1 to 5 pg / mL (0.9 to 4.6 pol / L). If you are below 1 you can indicate diabetes insipidus
