Certain tests have an indicator the show when the sample has been "diluted", but not every test has this indicator. Also, if ample water has been consumed urine typically turns clear leaving the authority to wonder why you've been drinking so much water.
That depends. If you are trying to take a HPT to determine whether you are pregnant or not and you drink a lot of water, the water will dilute your urine and might give a false negative. first morning urine is the best to test with as it will be the most concentrated with HCG.
No. only large amount of water will affect the result of pregnancy test.
What would be the point? It'd test negative or nothing at all..
no but it can effect a urine test for marijuana
nothing. it just makes it more clear. and it makes it so you have more urine
positive
no. If you add water to your urine the test will still detect the cocaine in it. giving positive results.
Depends on what kind of urine
3 to 4 days
Water
Can drinking enough water help me pass a urine drug test
Water in high quantities before a drug test dilutes your urine. Mix it with a B-2 vitamin to get some color to your urine. Cocaine is out of your body in approximently 3 days.
No, blueberries shouldn't have an effect on these tests.
If you are talking about diluting your urine with water to pass a urine test, then no, this would not be an ideal method to use in a urine test situation. If the color of your urine is too clear, many places that test urine will ask for another sample. Only time will clear your body of THC.
It's not necessarily bad to drink lots of water before a urine test but it could make you have to reschedule your appointment. The more water you drink the more diluted your urine is going to be. If your urine is to diluted they will make you come back after a day or two.
