When performing a blood alcohol concentration test is there a time frame what that results will no longer be valid?

We are not sure what you are asking, but if your question means "Is there a limit beyond which tests are no longer accurate," the answer is no. There will, however, be less alcohol in the body the longer the period before the test. In the case of blood samples, alcohol in the sample does not deteriorate and can be measured after long periods if the sample has been properly preserved.
In this sort of testing, any error will be favorable to the person being tested, as all errors cause the sample to test low.

How does chain length of alcohols affect viscosity?
The longer the chain length, the more viscous the alcohol
Why does simple diffusion end?
Diffusion is complete when there ceases to be a concentration gradient. For example diffusion has ended if the concentration of a substance is equal on the inside and outside of a permeable membrane, this state is also referred to as dynamic equilibrium.
How does etg testing work?
Ethyl glucuronide (EtG) is a direct metabolite of ethanol alcohol. The presence of EtG in the urine can be used to detect recent alcohol consumption, even after the ethanol alcohol is no longer measurable. The presence of EtG in the urine demonstrates that ethanol alcohol was ingested within the past three or four days, or roughly 80 hours after the ethanol alcohol has been metabolized by the body. As a result, it can be determined that a urine alcohol test employing EtG is a more accurate indicator of the recent consumption of alcohol as opposed to simply measuring for the existence of ethanol alcohol.
Can alcohols dissolve fats?
Really depends on the fat and alcohol you are talking about. Alcohol has two ends, hydrophilic end, OH group (water loving) and hydrophobic end (water hating). If the alcohol is long chain molecule with longer hydrophoic end, then probably will be able to dissolve fat better.
Why is mercury preferably used in a thermometer when compared to alchol?
Mercury does not evaporate as fast as alcohol, so mercury thermometers stay accurate longer.
Does sherry wine vinegar have alcohol in it?
Vinegar of any type - white grain, cider, sherry, wine, etc - results from the oxidation of alcohol molecules. Acetic acid (vinegar) molecules are no longer ethyl alcohol molecules. I suppose some homemade vinegar which hadn't completed the oxidation could contain a minute amount of alcohol.
Do people that drink alcohol live longer?
People who drink alcohol in moderation tend to live longer than those who don't.
I had 4 beer before 6 pm and a alcohol blood test at 8 am the next morning will the results be positive for alcohol?
No. Your body will filter out alcohol one drink (12oz beer) per hour if you're a guy. For a girl, it's longer. If you chugged them all at six you would be fine after ten that night.

How long after a DUI stop should you be given a breathe test?
The sooner the test, the more accurate the results. If you had just finished drinking (or were drinking) when you were stopped, your blood alcohol may still be going up so a delayed BAC may show more alcohol than you actually had at the time of the violation. If you had stopped drinking a while before being stopped, then your blood alcohol may be going down and the result would be a lower reading. Obviously the longer the wait for a BAC, the more a good attorney can argue about the results.

Librium is a benzodiazepine that effects you much like alcohol , but with a longer half life(stays in your system longer).It lessons withdrawal symptoms by weaning you off slower.
What is the balance in motion of particles when a concentration difference no longer exists in the solution called?
equilibrium
How does concentration of a fluid affect the motion of falling objects?
The higher the concentration of a fluid, the longer the time it takes for an object to fall and therefore the smaller the terminal velocity.
