i wonder if by taking b-vitamin supps you might be skewing blood tests. I remember I had a certain b vitamin or two tested way back by my bad doc....about an hour after i had taken a b complex. He told me, your test is high, stop taking vitamins.
moron. also was teh same doc who wanted to diagnose based on body hair count.
urine-- current results, hourly fluctuations, early mornig void, 10hr history, 24 hr history taken
blood-- current results plus couple of weeks history on some analytes
blood-- red blood cels, packet erythrocytes, history up to month or little more
hair-- they usually want from back of the head about 2-3 months growth, no bleaches or color, wash with Baby Johnson shampoo two weeks prior to cutting sample
Interesting problem, when to take urine/blood sample while on all kinds of supplements and medications taken on variety of schedules.
Worst or close to hopeless with saliva samples.
Test kits at Genova Diagnostics come with some number of possiblilities depending on type of test, test objectives and few other variables.
Advice is written and comes with a package.
I am sure not all possibilities are covered.
======================================
My last color was 10 weeks ago, 5 weeks ago shaved back of my head, now use only Baby Johnson shampoo.
At the moment I still put shaping paste (only on front of my head).
Getting ready for possible hair testing, still not sure if I want that, now, since I discovered NutriEval test.
