Testing for Malnutrition

URINARY AMINO ACIDS AND PLASMA AMINO ACIDS

  • Identify protein nutritional status. Deficiencies can occur from inadequate intake of protein, maldigestion, malabsorption, or over utilization of amino acids, often in times of stress such as mercury toxicity

RBC MINERALS

  • Analysis of your mineral levels

URINARY ORGANIC ACIDS

  • A complex panel of tests that looks at fatty acid, carbohydrate, energy metabolism, as well as B vitamin status, oxidative stress, detoxification and digestion function

METHYLATION (B6, B12 and folate insufficiencies)

  • COMPLETE BLOOD COUNT
    • Large red blood cells or anemia might give a clue. Check the MCV or mean corpuscular volume (the size of the red blood cells). If the MCV is greater than 95 you might have a methylation problem
  • HOMOCYSTEINE
    • This is one of the most important tests you can ask for. The normal level is less than 13, but the ideal level is likely between 6 and 8.
  • SERUM OR URINARY METHYLMALONIC ACID
    • This more specific for B12 insufficiency and may be elevated in the face of a normal serum B12 level or even homocysteine
  • SPECIFIC URINARY AMINO ACIDS
    • These can be used to look for unusual metabolism disorders involving B6 or folate or B12 that may not show up just by checking methylmalonic acid or homocysteine

ESSENTIAL FATTY ACID TESTING

  • It may be useful to test red blood cell fatty acid levels to look for the proper balance of fats. It can identify essential fatty acid deficiencies as well as excesses of inflammatory fats and trans fats.

MAGNESIUM TESTING

  • Serum magnesium is most often used, but rarely helpful. Level less than 2.0 can be significant
  • Red blood cell magnesium is more accurate, but still not ideal
  • Urinary amino acids or organic acids can identify poorly functioning metabolic pathways dependent of magnesium
  • Magnesium loading tests are complicated but accurate in assessing total body magnesium depletion. This requires intravenous magnesium and a 24-hour collection

ZINC TESTING

  • The zinc taste test using liquid zinc sulfate can be very accurate in picking up marginal zinc deficiency
  • Simply swish about 2 tablespoons in your mouth for a minute or two. It should taste horrible. If you immediately taste something bad, metallic or bitter, then you are OK. If you taste nothing or have a delayed taste, then you are likely zinc deficient. You can swallow or spit it out when you are done.
  • WBC or RBC zinc can also be useful
  • Alkaline phosphatase is a common blood test looking for liver or bone disease. It is an enzyme that depends on zinc and if it is low it indicates zinc deficiency. Most doctors only pay attention to high numbers, but if it is low (less than 70), you likely need more zinc.

25 OH VITAMIN D

  • Low vitamin D levels are a very good clue to poor nutrition, risk of osteoporosis, multiple sclerosis, seasonal affective disorder and more
