Fasting makes you more dehydrated than you would otherwise be. Without sugar and salt water just goes in and goes out rarely doing much to your hydration status. Plus people tend just not to have that much time to get rehydrated if they get their labs done first thing in the morning.
ETA my doctor has never ONCE told me to be sure to drink enough water not to get dehydrated
Your kidneys regulate water balance just fine. No need to take salt and sugar with it.

And what makes you "THINK" I don't listen to what my doctor says. You assume a lot. Amazing how so many assumptions from members here.
The rationale for fasting has been explained to you. Perhaps if your doctor does not follow the directions from the lab doing the test you need a different doctor.

The comment was made to the thread readership in general and was not directed at you. What makes you think it was? I did not quote you.

Thank you for your correction as always. Mine was a general comment too that many can change their lipids with changes in diets, what one puts in their mouths ongoing.
Fasting doesn't mean to not drink water. Fasting is done to ensure a more standard comparison from one time you've tested to the next so it is not unduly influenced by what you've recently eaten.
No reason to be dehydrated before a fasting test - drink as much water as you want and you'll avoid the issue! Don't invent some crazy conspiracy where there is none.
And perhaps they are making it easier by combining two "fasting" tests on the same occasion so you won't be doubly inconvenienced - they're being NICE...go figger.
Drinking water also makes it easier to find a vein.
I always drink water before blood tests unless they are in conjunction with a test that requires being knocked out.
And that's not a set in stone rule anymore
I had a rigid cystoscope with propofol anesthesia scheduled on same day as CT and blood work. (I had blood in urine and my urologist decided that she wanted to to see ct before she scoped me)
I was told to drink 16 oz water an hour before I went to Urology Center because of the dye used in CT. Totally new protocol.
All tests came back negative, DX was just urethral stricture with no prostate or kidney stone issues. All she had to do was dilate me before I woke up (Although, dilation can easily be done while awake with only minimal discomfort)

Because you don't stop or slow down in your intake of water just because you are fasting! Why would your doctor tell you this? He didn't say to stop drinking - he told you to FAST.
I don't know about you, but if I wake up thirsty, I drink. But not coffee...or tea...or juice if I'm fasting. And just because you're fasting doesn't mean you have to have labs done at the crack of dawn - are you sooooo hungry after 12 hours that you can't wait to drink a glass or two of water and then have labs done? Seriously... a little common sense. If you're hungry, you're even told to drink a glass of water - exactly what you'd do if you were fasting!
My doctor wanted me on medications immediately both times she saw the LDL over 200. How many people end up on cholesterol medication for life because of being dehydrated?
For some reason every time I have a lipid test, I must have a blood sugar and triglycerides test. Both of those do require fasting. MY triglycerides test and blood sugar were elevated because I wasn't fasting. Why do doctors do it this way? Honestly it seems they do it because these two tests will have something unfairly elevated no matter what you do... fast or not.
I have to ask, who told you those numbers were normal? They seem rather high. Do you eat a lot of sugar and fats?

Because the definition of fasting is no food, but includes water?

No, clearly it is genetic. These numbers have never moved my entire life.
When I was on a medically supervised liquid diet.. so I only drank medically supervised shakes all day.. they went way up. So you can drink all day long and still be dehydrated - kidneys just eliminate what you take in unless you have something like salt or sugar to hold it there. Why do you think you lose "water weight" when you start dieting. Cause you eat less food.
My doctor is fine with them as long as the blood sugar and the triglycerides stay low. Which they do, when I am fasting.

The A1C test is also the primary test used for diabetes management.
Well ok but I don't have diabetes so my doctor doesn't order it. She orders the lipid profile first which includes the blood sugar and triglycerides which are the gate way to concern and "lets consider drugs" discussion.

No you can't "drink all day and still be dehydrated".....not physiologically plausible or possible
Your erroneous ideas about how kidneys function in regards to presence or absence of "salt and sugar" are also unsupported with even a basic understanding of human physiology.....
