What Causes Presence Of Codeine In Urine?
Don't worry.You will clear drug test this time.
Detailed Answer:
Hello XXXX
I have gone through your query in detail.
There may be false positive cases.I don't agree with lab statement that hydrocodone does not show up as codeine in a urine test.
It really depends on sophistication of drug test.Some drug tests can detect the exact substance while others may not even be able to differentiate between the basic structures of Hydrocodone and Codeine.So,it can give false positive results.
Hydrocodone is metabolized in the body into Codeine.
Ideally it can be re-tested with a gas chromatograph mass spectrometer.It has the ability to distinguish between Hydrocodone and Codeine.However,it is a costly test.
Don't worry.You will clear drug test this time as earlier test was done around february month.
Hope I have answered your question.
Further queries are most welcome.

Hello XXXXXXX XXXXXXX
I have doubt that gas chromatograph mass spectrometer test has been done for confirmation in second test.
We have to understand the metabolism of hydrocodone.Hydrocodone is metabolized in the our body into Codeine,it may be the reason for positive codeine test.
Don't worry.You should go for repeat test,it will be clear out of your body by this time.
Don't think much about pharmacy error.It may be one of the possibility.
Hope I have answered your question.
