Hi,
I am looking for information on lab testing for Hypopituitarism.
Can anyone please post what are the common lab tests done for diagnosis of Hypopituitarism?
Thanks so much,

Note that hypopituitarism will occur in up to 30% of people who sustain a moderate or severe traumatic brain injury (TBI), and can sometimes occur even in mild TBI cases. Hypopituitarism can have symptoms very close to those of ME/CFS.1 Thus there is a real danger of misdiagnosing such symptoms ME/CFS when the true cause is hypopituitarism.

If a traumatic brain injury is involved, and ME/CFS-like symptoms ensue, testing for hypopituitarism would be advisable. The short synacthen test (also called the ACTH stimulation test) is a standard test for hypopituitarism, but this test is not very accurate, and in fact misses 40% of hypopituitarism cases. A more accurate but more complex and risky test for hypopituitarism is the insulin tolerance test.
