Hi, i am voluntarily drug testing for CPS because my daughter's father (who had physical custody) passed away suddenly due to a motorcycle accident leaving her "without a legal guardian" I have a previous history of using Methamphetamine. I am clean now or so i thought. Yesterday my test apparently showed positive for Methamphetamine. I know i haven't used. So far i have only came up with two possible explanations.

1. I just had to serve my ex boyfriend with a domestic violence restraining order. To make a long story short, not thinking, I ate some fast food that he insisted on leaving for me. And the 2nd being a cold medicine that I just remembered. I took one pill approximately 2 maybe 3 days ago called ST. JOSEPH DECONGESTANT-FREE HBP. Is it possible that this medicine caused a false positive? Thanks in advance for listening and any insight.

Was the test they gave you a rapid screening test or did they send it to a lab for testing? Anyway all false positive should be sent to a lab for GC/MS confirmation. GC/MS is the "gold standard" for drug testing whether it is urine, oral or hair drug testing. I am assuming you had a urine drug test. You need to request a confirmation test. If it was a rapid screening test like you can get at the store the St Joseph might have caused a false positive. I would need more info to give a better answer.

Hi Thanks for your response. I'm not sure if this urine test was what you are referring to. The worker just told me that i tested positive for Meth and i overheard her tell someone to send it to the lab. I didn't mention St. Josephs to her because i automatically assumed my ex-boyfriend had put it in the food he brought me. I seen the medicine later and wondered if that could have caused the positive test. The social worker thought i was lieing about using. I'm so depressed.

If the worker said "send it to the lab" my best guess is that it was, initially, a rapid screening test. Sending the sample to a lab is a good thing because they should do a confirmation test using the Gas chromatography–mass spectrometry (GC-MS) method. I am guessing it will show negative for meth.

If you didn't do meth then the lab test (GC/MS) should be negative and clear you.

Thank you again. You really helped me stay strong and stand up for myself today in court. They were really trying push me to accept court ordered services and supervised visitation based on that positive test. The lab results haven't came back yet. I have a rehearinging on Friday. :) This is a 3 hour trip to the county where my case is filed and very costly. I pray the lab results are back by then. Lol Thank you again

Glad I could help. Since it is a long drive you might see if they can reschedule the hearing. Tell them you are waiting for lab results to come thru. I get calls like yours every once in a while. I am third party administrator for hair drug testing so I have heard similar stories. People usually call me trying to get a hair drug test to prove they haven't done a particular drug. It can get a little expensive but they usually don't care if they can clear their name. Good luck.

Hi They lost my test. It never made it to the lab. They also lost my negative tests. They tested me again, same result. This time the judge told the worker to personally walk it to the lab. Is it me or does something seem funny here? In the mean time my daughter is grieving the loss of her dad thinking her mom is in denial and wants out of this craziiness. I know i can't afford a hair test but how much it cost? Thanks again

OMG. Those people are incompetent. Hair testing isn't all that expensive but I guess it is all relative. The name I use on this forum is my company name. Look it up on the web and give me a call. Ask for Marty

EXPOMED... I am 52 and I had to submit a UA but had no reservation about it as I knew that there was no reason for concern. As it turns out, I tested positive for Meth I was in complete and utter shock. I demanded that they retest in a lab and they stated that the cup UA out in the field was as accurate as any lab test and that they had no need nor would they be sending it to the lab. Of course they had the UA and I could not have anything else done. I felt that I had no rights at this point..Until I read your reply. I am taking Adderall 30mg ir 2xdaily, morphine sulfate 60 mg ER, amitriptyline, Prozac and Neurontin . I have been taking a few over the counter medications for sinus and cold symptoms which included: vicks vapor rub, vicks inhaler(which I use regularily) Sudafed and Nytquil for bed time a few nights. Could any of this of caused the same, a false positive for methamphetamine? Thank you in advance for your assistance in this matter. I will be attending a hearing on Dec 7th and would like to be able to argue my case at the hearing, with facts and an educated argument. Sincerely, Jade

Hey Jade, I am not a doctor so I can't say for sure but adderall might cause a false positive for meth but usually would cause a false positive for amphetamine. But you are taking many different things so there might be some cross reactivity. You really need to consult with an MRO (medical review officer). An MRO is a doctor trained to interpret drug test results and make a determination if something is causing a false positive. For them to tell you they are not going to send it to a lab for GC/MS confirmation is just wrong. I have the EZ Split Key Cup II drug test and this is what the test instructions say about a positive reading "Configurations of the Integrated E-Z Split Key Cup II can consist of any combination of the drug analytes listed above. This assay provides only a preliminary analytical test result. A more specific alternate chemical method must be used in order to obtain a confirmed analytical result. Gas chromatography/mass spectrometry (GC/MS) is the preferred confirmatory method. Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are indicated." So, you need to stand your ground and insist on a confirmation test but it might be too late because they might have thrown out the remaining urine that would be used for confirmation. I doubt if a rapid screening test like that would hold up in a "real"court but if it is not a formal hearing the judge/magistrate might accept the results as they are so don't let them screw with you.

My step-daughter is a former meth user. She has been clean for over 3 months and involved in a case with CPS. She suddenly started testing positive again periodically to a very low degree. She is also hypoglycemic and I'm wondering if this could be causing her to positive tests. I've read where diabetes can cause a false positive but can't find any information on hypoglycemia. Is this a possibility and how do we handle the testing if it is? And yes.....CPS is incompetent!!!!

Expomed Says:

I'm assuming it was a urine drug test. My next question would be: was it a urine dip test like you can do at home or was it a full GC/MS lab test. It sounds like it might have been a lab test. I doubt if being hypoglycemic would cause a false positive but I am not a medical professional. Part of it depends on what meds she might be on but for the most part being hypoglycemic won't cause a false positive. If you read some of my other posts I usually recommend people seek the help of an MRO. A medical review officer is a doctor trained to read and interpret drug test results and say why something might be causing a false positive. You can find an MRO in you r area by looking at their association web site aamro.com. Look for a link that says something like "locate a mro". You say she is a former user and clean for 3 months. In my dealing with substance abuse issues I have found that people sometimes aren't completely honest about what is going on. Since I do a lot of hair drug testing for custody issues it might be a way for her to shut up child protective services if she comes up negative on the limits of detection (LOD) hair drug test. {edited for privacy}

The tests that are coming back (and unfortunately I don't know how to read these test) are saliva tests. She had clean tests until her case worker changed. I'm trying to cover all our basis.I understand that we have to be cautious about what's the truth here. CPS is a joke. They want her to have a job, but expect her to just leave at the drop of a hat to come in when they say. There is a lot of problems there and I wouldn't put anything past them.

I used Meth one time on February 2,2014. First time in almost 2 years. Tested positive on the 3 what I new I would
. Just found out that 7 days later I tested positive again what was the 10th of February but My UA on the 8th was clean. All the ua's get sent to a lab. I don't understand how this could happen. I drink very little water or anything really because I can't keep My creatin level up I will get a diluted UA if I don't drink 60 grams of whey protein 2 hours before I UA and still times I'm diluted. I was very honest about My use but I didn't use between the 8th and 10th. How could this happen. I have court on Monday again and need help in why this could have happened. If you could help me understand why or if there is even an explanation.

It might be a good idea to have a hair drug test done. IT is better at showing a history (or lack there of) of substance use. If you are POSITIVE you didn't use meth than a hair test might workout better. Did you fill out and sign a chain of custody form for the urine test?? If not the lab could have mixed up your sample with someone else's. I would request the lowest limits of detection hair drug test, it would work to your advantage if you are trying to prove you didn't do anything. My name on this forum is my company name. If they don't edit this out give me a ring.
