No liability for a false drug test

A drug test.
A false positive.
The employee loses his job.
Is the drug-test lab liable to the employee?
In Texas, the answer is NO, because "the third-party testing entities hired by an employer do not owe a common-law negligence duty to their clients’ employees."
