It depends on the context of the test you're referring to. If you're asking about a substance test, such as for drugs or other analytes, "dilute" typically means that the sample may have been watered down, which can affect the accuracy of the results. If you have specific guidelines or procedures for the test, those will clarify whether dilution is expected or acceptable. Always refer to the testing protocol for precise information.
Drinking water will not dilute an EtG test for alcohol consumption, as EtG is detectable even with high water intake. It is best to abstain from alcohol for a few days before the test to ensure accurate results.
No
No. A "dilute drug test" is one where the test can't find certain levels of certain enzymes. Those enzymes are also in blood, so you're safe. You do, however, still have blood in your urine, where it should not be.
yes it can.
If your urine is too diluted, the test may show a false -. It's best to test with your first morning urine to ensure it is at it's highest concentration.
Don't just sit there and slam water trying to get enough in you to pee.
You can't dilute urine, because the only thing you'd have to dilute it with is tap water, and that would show up on the urinalysis. Urine does not contain H2O. It's been chemically changed by the time it comes out as urine.
Because there's a chemical reaction going on.
No but if you swish some visine around in your mouth right before, it will dilute the sample.
Calcite is a common mineral that fizzes when in contact with dilute hydrochloric acid due to the release of carbon dioxide gas. This reaction is a simple test used to identify calcite in the field or in the lab.
Carbonate minerals, such as calcite and dolomite, will typically react with dilute hydrochloric acid by releasing carbon dioxide gas. This reaction can be used as a simple test to identify these minerals.
When dilute HCl is added to Na2CO3 in a test tube, effervescence (bubbling) occurs due to the formation of carbon dioxide gas. This is because the reaction between the acid and carbonate produces carbonic acid, which quickly decomposes to release CO2 gas.
