I am 25 and had a blood test the day after Christmas (not the best time, I know). My doctor told me that my blood pressure was higher than normal as was the amount of sugar in my bloodstream. Is it possible that having eaten lots of junk food during the holidays skewed my results? Also, doctors appointments have always made me nervous, so could that have affected my blood pressure? I could use some improvement in my diet, but I think I eat healthier than most people my age, so these results were a shock to me.

The blood test tells you what's going on at the time your blood was drawn and indicate quite accurately what's happening inside you body. Your doctor is telling you if you continue on the same diet path that you'll more than likely have some health problems down the line.
Blood pressure levels vary day to day hour to hour minute to minute, depending on the activity or stress you're under at the time of the BP test.

Stress at the doctor's office can affect your blood pressure, but what were your numbers? If the blood glucose test was done properly (after overnigt fast), I think it should not be affected by eating junk foods for few days before. I would recommend you to make the full blood glucose testing that involves glucose tolerance test, which can show if you have diabetes or not.

Did you fast before your blood test? There are some tests (like glucose, for example) that require fasting for a more accurate picture.

Some people have "white coat syndrome" but most do not. You would really need to monitor your BP for awhile with multiple readings to see if it is continuously high.

Oh I get the "white coat" thing where my systolic BP goes real high. Like once it was 145/70 and usually I'm 95/60. Also I found out in blood chemistry tests that dehydration can skew results. I tend not to drink enough.

That could've been the case with me. I had a urinalysis at the same time and will have to redo it because I was too "dry".

My doctor's office says "Don't eat* anything so many hours before the blood draw for the test!". Basically I schedule the test for the morning and don't have anything to eat OR DRINK* (except water) after 9:00 the evening before the blood draw.

*Note they said to not eat anything, but that includes not drinking anything with sugar in it! They don't say that.

Basically just drink water.

Could you have taken any OTC medication like Advil, Tylenol, etc.? Some foods can affect blood test results, especially junk food because of the high sugar content. I don't know if stress would have an affect on blood test results though, but it would on bp. Blood test results can fluctuate, so if it is something to worry about your doctor would recommend retaking the tests in a few weeks just to make sure. You are only 25 and the chances of something seriously wrong with you is pretty low on average, especially since you eat healthier than most young adults.

Alot of things can affect the blood tests result. This is why my doctor always told me to fast before take blood test for accuracy. Example like if I take blood test tomorrow, today evening I will stop eating. Just only drink water, no juice (becuze juice contain sugar).
For sure if you eat like a whole box of ice cream before going do a blood test, your sugar level will be higher.

High blood pressure also can be affect too. I remember one time I run from the parking lot to the doctor office, eventhough it was short distance, it does give me high blood pressure result as well as fast heart beats. It was said my heart beat faster than normal people, LOL! After like 30 minutes, I got my heart rate and blood pressure measure again, and this time it was Normal. So definately the running affect the result.

For accurate result, fast the evening before your blood test. Like after dinner today start fasting, then tomorrow you ready for the blood drawn.
