You should discuss this with your attorney, he/she can explain what is happening in your specific case. That being said, most crime labs only conduct "presumptive" analysis which means that your blood offered values that were presumptive of meth use. Your attorney has asked for a more specific value, sometimes legal drugs will provide values when testing for illicit drugs is performed. There is no "legal" limit for an illegal drug AND even legally prescribed dosages, taken in compliance with the prescription can result in DUI charges, Ambian is drug that has caused many DUI arrests, prosecutions and (unfortunately) convictions for unsuspecting (otherwise law abiding) citizens.
