Inconistent Results In Test For Cocainei
UpdatedI have a client who teste positive for cocaine in a urine test. Two hours later she tested negative. In the second test it said the creatnine level was low. I had her take a hair follicle test 71 days after the oringinal urine test which indicated no cocaine for the period of time which I believe was 90 days. Why would there be those inconsistencies?

You should check with her about what else she was taking.
There are some antibiotics that can sometimes cause these oddities in some people. For example, the sulfa based on that's commonly prescribed under the brand name Bactrim, which contains Sulfamethoxazole and Trimethoprim is a known culprit for throwing off such tests and giving strange results.

If she'd taken it or a similar medication within a few weeks of the test, it may have caused it.
Did she report being on any medications?
