Brief Answer:
I know this one.

Detailed Answer:
Hydrocodone sometimes overlaps in its metabolism with morphine.
The normal test is Run by putting proteins that binds morphine onto a piece of paper and seeing what sticks. XXXXXXX seeds,

sometimes antibiotics.
http://www.ncbi.nlm.nih.gov/pubmed/0000
some metabolites of hydrocodone
(hydrocodone metabolizes to hydromorphone )and.. just sticky urine can interfere with the testing.

GC MASS SPECT is a more accurate test and should always be used for confirmation.
HAIR analysis can only be done by GC Mass Spect.

Doing a hair test is very reliable and very very sensitive to use of morphine but will show any morphine used during the time the hair was growing (months) (the time the hair was there).
