This thought just occurred to me:
If I know I'm having blood work done, and there might be a possibility of a urine analysis before/after the blood work... should I attempt taking 10X the daily amount of B complex vitamins to change the color of my urine for the dilution method? Or will that be detected in the blood test and raise some red flags?
The substitution method is sounding better and better as I research this...
No flags will be raised as a result in using vitamins.
The proper vitamin for "color" is B2 (Riboflavin). But it must be understood that specimen validity checks had become SOP in recent years, rendering sample color the least aspect in determining an overly-diluted urine sample. Even samples with a nice yellow color to them can still register unsatisfactory specific gravity and creatinine (the two urine constituents thats tested in determining overdilution) levels.
Therefore, when utilizing dilution techniques, the focus now is to ensure that the creatinine and S/G are within satisfactory ranges. Tips to help accomplish this are found in the Dilution "sticky" thread. When going the Dilution route, its a good idea to have some validity test strips at hand so you can keep tabs on the creatinine and S/G when diluting. These kits are inexpensive and are found online by doing a Google search for "drug adulteration test kits".
Thank you for the reply. I have scoured the sticky for tips on using the dilution method. However, I couldn't get any solid advice on increasing my S/G. Since I know for a fact I will be having blood work done (they told me to fast after midnight and only drink water/black coffee if needed) I cannot use gatorade to increase my S/G.
Do you have any recommendations for increasing my S/G without intaking any sugary drinks or any other substances that could show up as red flags on a blood test?
I may have missed this, but would Rolaids or Tums work for increasing the specific gravity of urine? If so how much should be ingested?
