Ok so my boyfriend called the lab back last night and they said it was invalid neither positive or negative and they said they will let the employer know and then they decide. So I know he went in today and went to them and said they had called and told them what they said. They said they haven't heard of that before. So the main guy wasn't there so I guess we don't know if they will just say whatever or will retest. Hopefully they will just say whatever but if not a retest is fine. Has anyone ever had invalid?

When a sample fails because it is overly dilute, as tested by specific gravity and creatinine levels, it is impossible to get a meaningful result. The sample is considered to be invalid. Dilution techniques add creatine and electrolytes to correct this problem. Simply drinking a lot of fluids to lower the concentration of THC metabolites in your urine tends to produce samples that test as overly dilute.

Substitution techniques always work, but take some practice and can't be used in a closely observed test.

Load up on creatine supplements, take heavy-duty B vitamins, stick with the Gatorade and aspirin, don't overdilute. All the info is contained in the threads linked in my earlier post.
