One of my friends said that she was diagnosed with depression and put on medication. The doctor ran some blood tests and when she got her results they said it was depression. I had never heard of this before. Have you?

Still looking for answer.  Thanks Lorie for the websites.  I found this part of an article on WebMD interesting:

Diagnosing Depression and Lab Tests

Your doctor can usually tell if you have depression by asking you specific questions and doing a physical exam. Your doctor may, however, ask for lab tests to rule out other diagnoses. Your doctor will likely do blood tests to check for medical conditions that may cause depressive symptoms. He or she will use the blood tests to check for such things as anemia, and thyroid, hormone, and calcium levels.

Diagnosing Depression and Other Testing Methods

The doctor may include other standard tests as part of the initial physical exam. Among them may be blood tests to check electrolytes, liver function, and kidney function. Because the kidneys and liver are responsible for the elimination of depression medications, impairment to either of these two organs may cause the drugs to accumulate in the body.

So, what it sounds like to me is this:   blood tests to check for medical conditions that may cause depressive symptoms. He or she will use the blood tests to check for such things as anemia, and thyroid, hormone, and calcium levels.  And that there is not a blood test for depression, but rather, " lab tests to rule out other diagnoses" 

So, that is my thoughts.  Does this make sense?  It does to me.  There does not appear to be a specific blood test for depression, but other blood tests to check for other things. 

What does everyone else think???  I may start a new thread because this is interesting.

Hi Jayne,

Looks like you've got lots of links there.  I've had numerous blood tests and other tests done, but they've all been, as in the info that Heidi posted, to rule out other diagnoses or to check for organic causes of my depression and depression-related symptoms.  My (non-medical) thought is that her diagnosis was a result of what didn't show up on the blood tests, rather than what did.

Hope those links Laurie posted were helpful in finding what you were looking for.  :)
