OP, I don't know your age but Medicare approves 2 appointments a year, 1 is just a yearly "look" at bloodwork, and the other is a regular physical exam. Both are done along with labs. I once asked why I was having this done twice a year and she said because I was on a medicine and Medicare approved it. Of course, they will order stuff as often as they can, as long as someone will pay for it! My dr. did tell me I didn't need to fast any more, they had determined that didn't change lab values much. I disagreed with that and continued to fast before my tests. Try eating a bit less animal protein and see if that affects your numbers. I have a friend who did that and his numbers are fine now.

Translation: "I can get paid for it and it also helps in legal defense when you sue me if I've done it more frequently."

Once a yr routine blood work is good enough for screening. Some conditions require more frequent, specific testing: BS in DM, BUN/Cr in renal failure, LFT in liver failure, blood counts in anemia or certain treatments for ca etc, 'lytes when using diuretics-- frequency depending on troubles they've caused in a given pt.


BS & triglyceride levels are the only two tests that are significantly affected by the fasting vs fed state before the blood draw (and we can argue that a 2hrpp test is better for BS screening).

Re: dehydration, drinking water & BUN levels-- we lose ~1.5L of water /day in urine, sweat, breathing, BMs. (More when exercising/working & sweating.)...Obviously, it needs to be replaced on a daily basis. Animals & plants (ie-food) are about 70% water on average, so we can get almost all the water we need just by eating.

A given pt will have a slightly higher BUN when relatively dehydrated compered to his level when well hydrated---so, unless you have his baseline, well hydrated level on file for comparison, a single, isolated test is meaningless.---More importantly, if your doc needs a BUN test to see if you're dehydrated when you appear in the ER with dry tongue, wrinkled skin and a history of diarrhea and vomiting for 2 days, maybe you should get a new doc (better-- an old doc).

Thanks to everyone except one who has posted with intelligent and respectful information. I have studied your info and at least I feel better about the numbers. I will try to drink more water daily and have my Doc retest in a month or so once I feel my water intake has increased. I am 6'-3" and weight 292. So, I know my weight needs to come down and that is the hard part for me. There are too many foods that I enjoy that are not indicative of a healthy diet. I feel I have quite a few changes that must be made for my health now.
