Brief Answer: You are likely to test positive (not to pass). Detailed Answer: Hi and thanks for the query, I am afraid the timeline, given the half life of the drug makes it very difficult for you to pass the test. It is true that drinking much fluids decreases its concentration in the blood. However, the time separating the intake and when you have to pass the test, considering its half life, makes it very very probable for you to test positive. Thanks and kind regards as I wish you the best of health. Dr Bain

Brief Answer: They are accurate, but however, less sensitive Detailed Answer: Hi and thanks for the query, Home tests are generally used as a screening tool. NOt that they are not accurate. THEY ARE HOWEVER LESS SENSITIVE THAN THE ROUTINE TESTS THAT ARE GENERALLY USED. FROM MY EXPERIENCE, i DO NOT THINK WITH THE TESTS GENERALLY USED, THE TEST COULD FAIL TO DETECT OR TEST POSITIVE. Thanks and kind regards Dr Bain
