do you know if the test your parents are using is just a single dipstick? If it is, just do like the other person said and dilute your urine. All you need to do is drink 48 oz of water, or a drink that is chiefly water like gatorade, tea, or koolaid. You'll be urinating every 15-25 minutes, drink 4 oz (half a normal glass) each time you urinate and your urine will be dilute enough to pass a home test. The Vitamin B just makes your urine more yellow, its not needed to pass the actual test, so don't sweat it if you can't get it. The third time you urinate it should be clean. Use your midstream urine to help your chances of passing.
