Hi there,
This is Dr Basu, experienced Internal Medicine Specialist.
I am here to address your concerns and provide great service.

Which drug you tested positive for?

Zyprexa should not cause any false positive.

OTC cold medications can for amphetamines sometimes.

GCMS testing of the sample will eliminate any false positive screen.
