Thirty to 60 mL is the standard amount of urine obtained in a midstream urine specimen. At least 3 mL are required to perform a urine culture. Twenty milliliters are necessary for routine urine studies.
Routine urine is 12 mL.
No. The test stick is held in the urine stream. No matter how much urine comes into contact with it, it can absorb only so much.
None.

Millions of people worldwide depend on oxygen machines. As an everyday routine, a part of their lives, oxygen machines provides much needed oxygen for many people that can't breathe on their own without assistance.
Routine urine is 12 mL.
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.
Drinking too much water before a drug test can cause an inconclusive result. Any urinalysis will be skewed from too much water in the sample.
Yes, it will contaminate the sample causing them to mark it as Unusable. But doing so can be seen as tampering your urinalysis and get you in big trouble. If its just a home test it wont help you much.
A blood drug test is when a person draws blood from you and checks it for any sign that you have been drinking or using illegal drugs. A urinalysis drug test is when you urinate in a cup and a person checks it for any sign that you have been drinking or using illegal drugs.
Depends on whether or not it shows possible infection or something. If positive for infection then culture would be needed. Another cost. Call a lab in your area for cash pays they do charge less.
1. Both wastes and needed materials, such as glucose, are removed from the blood. 2. Much of the needed material is returned to the blood.
It varies and depends on how long and much you used. Heroin stays in urine 2-4 days so if you have a urinalysis you need to be on the safe and take the test after you have not used in 4-5 days.
yes, very much so!
From the original filtrate, a lot of much needed electrolytes (Sodium e.t.c) are reabsorbed (absorbed back into blood), a few substances secreted further into the urine, then loads of water reabsorbed to fine tune body water to exactly how much you need(as much as possible), making urine far more concentrated than the original filtrate.

when the probation department comes to you for a urine test, they give you a small cup that you have to urinate into. Usually they prefer to have it as full as you can get it, but, it has to be at least a fourth the way filled up.
