Micronutrient Testing

About The SpectraCell Test

SpectraCell’s Micronutrient test provides the most comprehensive nutritional analysis available by measuring functional deficiencies at the cellular level. It is an assessment of how well the body utilizes 31 vitamins, minerals, amino/fatty acids, antioxidants, and metabolites, while conveying the body’s need for these micronutrients that enable the body to produce enzymes, hormones, and other substances essential for proper growth, development, and good health. Repletion recommendations are made based on need.

This test is unique because it measures the functional level and capability of micronutrients present within white blood cells (lymphocytes), where metabolism takes place and where micronutrients do their job – thus taking a person’s biochemical individuality into account. Unlike static serum measurements, which only assess the concentration of nutrients present outside of the cell (extracellular) and only provide a glimpse of your health, SpectraCell’s Micronutrient test is a long-term assessment (4-6 months) that addresses the functional impact (performance) of micronutrients – what really matters.

Why is nutrient status important?

Virtually all metabolic and developmental processes that take place in the body require micronutrients, and strong evidence suggests that subtle vitamin, mineral, and antioxidant deficiencies can contribute to degenerative processes such as arthritis, cancer, cardiovascular disease and diabetes. Evaluating micronutrient status can therefore be the first step in identifying metabolic inadequacies while shedding light on the possible underlying causes of complex chronic conditions.

Vitamin deficiencies are not just a reflection of diet. We are all biochemically unique and nutrient deficiencies vary from client to client, and do not necessarily correlate directly with nutrient intake, as many factors beyond diet determine whether nutrient function is adequate. These include

  • biochemical differences
  • genetics
  • absorption
  • metabolism
  • and age

Who could benefit from micronutrient testing?

Many disease conditions and medications can have an effect on nutrient levels. Every biochemical process in the body depends on specific nutrients to carry out the process. Those who are suffering with the following could benefit from micronutrient testing:

  • Inflammation
  • Resistance to weight loss
  • Hormonal imbalances
  • Decreased energy
  • Depression
  • Lack of proper blood sugar regulation
  • Inability to burn fat or gain muscle

are just a few symptoms that can result from a lack of vital nutrients. If you are feeling unhealthy, a nutrient deficiency may be to blame.

Extensive scientific and clinical studies spanning over 50 years have repeatedly demonstrated that micronutrient deficiencies can adversely affect health. These deficiencies can set the stage for chronic disease and compromised immune health at any stage in life, particularly if they persist.
