positive
On rare occasions you can encounter a false positive due to improper testing, expired pregnancy tests, rare medical conditions such as certain types of cancer, evaporation lines, a recent pregnancy or a chemical pregnancy.
Yes. I have been a Drug and Alcohol Counselor in the State of California for 17 years. I've conducted UA on thousands of individuals. I also have personal experience of myself testing positive for methamphetamine multiple times after taking Bronkaid for my asthma. I've seen innocent people have their probation or parole violated and sent to jail for taking ephedrine and psydoephedrine products without counselors, parole officers, probation officers, DAs, PDs and Superior Court Judges doing the research or at least calling drug testing company.
If you have the correct testing strips you could test yourself for blood in your urine. If the test is positive you should see your medical care provider as soon as possible so she/he can do follow up tests do determine the cause of the bleeding.
Testing Truths says, "Currently, 50 nanograms of THC metabolites per millimeter of urine defines a "presumptive positive" by NIDA certified labs. These cutoffs are not mandated for all testing facilities. The lab your sample is sent to may use a cutoff level of anywhere from 50Ng/ml to 15Ng/ml for confirmation testing, The fact is, methodology, accuracy and cutoff levels vary from lab to lab. This makes it extremely difficult to take appropriate counter-measures."Source: http://www.passitkit.com/testing1.htm
Lidocaine will not trigger a positive drugs of abuse screen.
Topical anesthetics derived from cocaine (does not include lidocaine or novocaine) may show fail positive but lidocaine no. If you truly did not use cocaine yet still came up positive, you should insist on additional testing (a GC/MS test ).
No. Taking this preparation will not affect with allergy testing.
Yes, most allergy treatment centers will do allergy testing for a variety of common allergens. In addition, doctors at the allergy center can also prescribe appropriate allergy medications for your daughter.
Food allergy testing can be done in the doctor offices. If you cannot get to one try the free clinic to see if they could do it for you.
Provocation testing involves direct exposure to a likely allergen, either through inhalation or ingestion. Positive reactions from any of these tests may be used to narrow the candidates for the actual allergen causing the allergy.

Skin allergy testing is usually done by placing a series of adhesive patches on the skin containing potential allergens, or allergy-causing substances.
Allergy testing usually must be completed by a physician or trained allergist. One can contact their current healthcare provider to obtain information regarding allergy testing. Sometimes it may be required to send the patient to an alternative testing facility if the current one isn't capable of allergy testing.
Most often nuts. You can learn about testing for the allergy at http://www.peanutallergy.com/test-diagnosis.html
Significant allergic reaction
I had a reaction to Lidocaine at a dentist visit and then during a mole removal. My doctor had me tested at an allergist. I was tested with diluted pure lidocaine and found to be allergic. You can be tested but according to my allergist it has to be on the pure drug, not a name brand because they contain other substances. Allergy to Local anesthetics is extremely rare. Allergic reactions often present as rash and hives, but can be serious causing airway problems including swelling of the throat, tongue, and spasm of the airways of the lungs leading to wheezing and shortness of breath. Cardiovascular collapse and death are the worst senario. It is very common for people who have a "reaction" from local anesthesia in the dentist office to mistake the reaction for a lidocaine or novocaine allergy when in fact the reaction is due to epinephrine(adrenalin) which these anesthetics often include, designed to decrease bleeding and prolong the length of anesthesia. The reaction to epinephrine is caused by it's absorption into the bloodstream. The reactions commonly associated with this include anxiety, rapid heart beat, palpitations, changes in blood pressure, and shortness of breath. Local anesthetics may also contain preservatives which may cause reactions as well. Testing for lidocaine allergy can be done. Contact an allergist.
