Which labs in the U.S. do HER1 testing?

[Stephanie]

For those of you who have had HER1 testing done, do you know which lab in the U.S. your samples were sent to? My mother's onc has agreed to test her pleural effusion fluid for HER1, but the lab he uses in San Diego doesn't do the test.

Thanks in advance.
