Vitamins Profile D and B12 Blood Deficiency Tests

What is a Vitamin B and D blood Test?

Vitamins are organic compounds necessary to sustain life, most taken from food. A lack of them means the number of healthy red blood cells decreases.

Why get Vitamin Blood Tests for B and D?

A person who has deficiencies may experience symptoms like:

  • Fatigue.
  • Breathing problems.
  • Dizziness.
  • Lack of concentration.
  • Irregular heart rhythm.

Vitamins Instructions for use:

Please take your test samples in the morning. Take it at least one hour before any medication.

Also, here are some tips for collecting your sample:

  • Drink plenty of water, as being well-hydrated will make it easier to collect your sample.
  • Shower before you take your sample or run your hands under warm water for a few minutes, as this improves blood flow.
  • Do some exercise (move around, go for a walk, etc.) to get the blood flowing.
  • Let gravity do some of the work by keeping your arm below your heart level.
  • 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 the finger.
  • Re-warm your hands during collection where needed.

2 Vitamins Biomarkers:

  • B12 helps produce red blood cells, which carry oxygen around your body.
  • D: measures how much D you have in your blood, essential for healthy bones, teeth and muscles.
