 Vitamin Kit Instructions for use

Please take your Vitamin Blood Test kit sample in the morning. But please take it at least one hour before any medication.

Moreover, when you collect your sample, try the following tips:

  • Drink plenty of water. Being well-hydrated will make it easier to collect your sample.
  • Shower before you take your test or run your hands under warm water for a few minutes, as heat improves blood flow.
  • Do light exercise (move around, walk, etc.) to get the blood flowing.
  • Ensure your arm is below your heart level – let gravity do some of the work.
  • Nails that are too long can make it difficult to collect a sample.
  • Do not shake the sample vigorously, but invert the tube gently 10 times. (gently swirl the tube after each drop of blood).
  • Do not squeeze (milk) the finger.
  • Re-warm your hands during collection where needed.

Furthermore, view here for instructions on how to take a sample at home.
