What Are The Possibilities Of An Inconclusive Pre-employement Drug Test ?

Thanks for writing to us.
First of all being flagged suspicious does not mean that you have been found guilty.
The first urine sample of the day is always strong and contains all the metabolites in a bit higher concentrations.
Taking pain killer like ibuprofen or a muscle relaxant or a nasal decongestant spray or taking any herbal medicine whose exact composition is not known can cause falsely doubtful results. Even exposure to spirit or passive smoking for long hours can cause a false positive test.
To pass the test it is best to stop taking all kinds of medicines two days before the test, restrict coffee intake and drink plenty of water and a tablespoon of vinegar daily for 2-3 days. This will most likely clear your urine from all the contaminants.
I hope my answer and recommendations are adequate and helpful. Waiting for your further follow up queries if any.
Wishing you good health.
Regards.
