Will the lab still test a very diluted sample and will cocaine still show up if it is diluted with lots of water?

It really depends on the amount of cocaine that was taken, and the strength of the test. If a lab test probably caught.

What is a negative diluted urine sample?
A diluted urine drug test is one where the sample was diluted. It happens in two ways--you drank too much water to make yourself pee (DOT's standard says drink no more than 40 ounces of water), or you put water in your sample after you peed it out.A negative diluted test says "no drugs in this sample passed the test thresholds, but it was diluted so there MIGHT be drugs in here." Basically, a diluted negative is a test failure.
How do you dilute urine for a lab test?
There is none. Most labs cannot get a good reading if the urine sample is very diluted and will know this is the reason. At best it would require submitting another sample to be tested. Some states consider submitting a diluted sample as a violation and will still obtain another to get a good reading.

How to calculate BOD value in a sample?
if unseeded, BOD = (D1-D2)/Pif seeded, BOD = ((D1-D2)-(B1-B2)f)/PD1 = DO of diluted seeded wastewaterD2 = DO of wastewater after incubationB1 = DO of diluted seed sampleB2 = DO of seed sample after incubationf = ratio of seed volume in seeded wastewater test to seed volume in BOD test on seedP = decimal fraction of wastewater sample used. (vol. of wastewater)/(vol. of dilution water plus wastewater)Maybe that helps
If i mix 1 liter of coke with 1 liter of water will the sugar be reduced or will be equal?
The term is diluted. The sugar is still there, just 'spread out' into a larger volume along with all the other ingredients. It can be called a diluted solution.

Is staining what you call it if you diluted a blood sample with distilled water and the red blood cells burst?
You can certainly expect the blood cells to stain the water as their cell membranes rupture from being in a hypotonic solution. The term that describes this is "To lyse". Blood cells lyse in distilled water.
