I don't believe that carnitine, or lipoic acid will show up on testing.
(unless carnitine levels are ordered, which they are not typically).

B12 will show false elevations, so stopping that for 3 or more days is advised. You should have some stored by now, and not suffer this hiatus.

Magnesium levels have a large middle area of "normal", but I would still take that to see if you are edging into "high" with your supplements. That would be useful to know. So if you want that result, keep taking what you are taking for magnesium.

B-complex will read on blood testing. So stopping that would be a good idea for several days. B6 is stored for several days and not all excreted quickly. The benfotiamine is also stored, but it might be in tissues and not the blood.

What tests are you planning on having? Iodine of course could affect the thyroid panel in some way.
Typically high vit C should be avoided, as it can affect some blood work results. I'd stop that for at least 3 days.

You will want a renal panel, to check your kidneys. That is important.

Oh, I hope this post came earlier before my annual physical exam. I should have stopped the Vit C. I am taking Vit C at 500mg a day.

However, since yesterday, I am taking 1000mg a day because I developed.

Thank you Mrs.D. Everyday, there is always something new that I learn from this forum.

Here is a link with all the potential problems...of high dose Vit C and tests/drugs.

500mg might not be high enough... I don't know where the cut off is for it. The glucose testing is the most sensitive I believe.

This link clarifies Vit C and B12 interaction as not accurate with follow up testing:

This is a new doctor, but their usual tests include a kidney panel, potassium, magnesium, calcium, etc. And a urine test.

The additional tests I will request are for Vitamins B1, B6, B12, D. Also test for uric acid (because of the d-ribose I'm taking).

What else do you recommend?

Sounds like a good beginning. I would assume they do liver panel too?

Some potassium may test high if the sample lyses (bursts) the red cells. This happened to me last time, because they used a butterfly thin needle to get my small vein. Doctors know about this though. It is very common to have factitious highs in potassium. Just warning you on that one.

Yes, I think they do liver as well. It's an annual physical kind of thing.

I'm glad I can keep taking the magnesium, although it hasn't been working all that well lately on the foot cramps. I guess I'll stop the multi-vitamin, too.

Thanks, mrsD!
