How can you test for pituitary disfunction other than an MRI?
I had one dr tell me my pituitary gland was sluggish and that could be what's causing all my problems. I had an MRI, but they didn't see anything. I've read that MRI's only pick up tumors up to a certain size though. Is there a blood test or another way to find out if my pituitary gland isn't working?

From an online encyclopedia:
"The diagnosis of hypopituitarism is made on blood tests. Two types of blood tests are used to confirm the presence of a hormone deficiency: basal levels, where blood samples are taken–usually in the morning–without any form of stimulation, and dynamic tests, where blood tests are taken after the injection of a stimulating substance. Measurement of ACTH and growth hormone usually requires dynamic testing, whereas the other hormones (LH/FSH, prolactin, TSH) can typically be tested with basal levels. There is no adequate direct test for ADH levels, but ADH deficiency can be confirmed indirectly; oxytocin levels are not routinely measured."
