Background

Nutritional panel testing aims to identify nutritional deficiencies that will lead to personalized nutritional supplement recommendations. Testing is proposed both for healthy individuals to optimize health and for patients with chronic conditions (eg, mood disorders, fibromyalgia, chronic fatigue) to specify supplements that will ameliorate symptoms.

Genova Diagnostics offers nutritional/nutrient panel testing. Among tests this company offers is NutrEval FMV, which involves analysis of urine and blood samples and provides information on more than 100 markers including organic acids, amino acids, fatty acids, markers of oxidative stress (direct measurement of glutathione and CoQ10, and markers of oxidative injury and DNA damage) and nutrient elements (see Table 1).1

Genova Diagnostics produces a report that includes test results categorized as normal, borderline, and high need, along with recommendations for supplements and dosages for items categorized as high need. NutrEval FMV patient reports can recommend supplementation or any of the nutrients listed in Table 1 if they are found to be areas of high need.

A related test, the ONE (Optimal Nutritional Evaluation) FMV also by Genova Diagnostics, limits testing to the organic acid, amino acid, and oxidative stress marker categories.

SpectraCell Laboratories offers a micronutrient test that measures functional deficiencies at the cellular level. The test assesses how well the body uses 33 vitamins, minerals, amino and fatty acids, antioxidants, and metabolites (see Table 1). SpectraCell categorizes test results into adequate, borderline, and deficient, and offers supplementation suggestions based on each patient’s deficiencies.

Regulatory Status
Clinical laboratories may develop and validate tests in-house and market them as a laboratory service; laboratory-developed tests must meet the general regulatory standards of the Clinical Laboratory Improvement Amendments. Nutrient/nutritional panel testing using urine and/or blood samples is offered (eg, NutrEval FMV and ONE FMV by Genova Diagnostics; micronutrient testing by SpectraCell) under the auspices of the Clinical Laboratory Improvement Amendments. Laboratories that offer laboratory-developed tests must be licensed by the Clinical Laboratory Improvement Amendments for high-complexity testing. To date, the U.S. Food and Drug Administration has chosen not to require any regulatory review of this test.

Policy:
(NOTE: For Medicare Advantage, please refer to the Medicare Coverage Section below for coverage guidance.)

Nutrient/nutritional panel testing is considered investigational for all indications including but not limited to testing for nutritional deficiencies in members with mood disorders, fibromyalgia, unexplained fatigue, and healthy individuals.


Medicare Coverage:
Per LCD L34914, Micronutrient Testing for NUTRITIONAL deficiencies that include multiple tests for vitamins, minerals, antioxidants and various metabolic functions are never necessary. Vitamin or micronutrient testing may not be used for routine screening. Once a beneficiary has been shown to be vitamin deficient, further testing is medically necessary only to ensure adequate replacement has been accomplished. Thereafter, annual testing may be appropriate depending upon the indication and other mitigating factors. For additional information and eligibility, refer to: Local Coverage Determination (LCD): Assays for Vitamins and Metabolic Function (L34914). https://www.cms.gov/medicare-coverage-database/details/lcd-details.aspx?LCDId=34914&ver=48&Keyword=nutritional+test&KeywordSearchType=Or&Date=&PolicyType=Both&ArticleType=SAD%7cEd&Cntrctr=323*1&KeyWordLookUp=Doc&SearchType=Advanced&CoverageSelection=Both&kq=true&bc=IAAAACAAAAAAAA%3d%3d&.

[RATIONALE: This policy was created in 2015 and has been updated regularly with searches of the MEDLINE database. The most recent literature update was performed through November 7, 2017.

Evidence reviews assess whether a medical test is clinically useful. A useful test provides information to make a clinical management decision that improves the net health outcome. That is, the balance of benefits and harms is better when the test is used to manage the condition than when another test or no test is used to manage the condition.

The first step in assessing a medical test is to formulate the clinical context and purpose of the test. The test must be technically reliable, clinically valid, and clinically useful for that purpose. Evidence reviews assess the evidence on whether a test is clinically valid and clinically useful. Technical reliability is outside the scope of these reviews, and credible information on technical reliability is available from other sources.

Direct evidence that nutrient/nutritional panel testing improves health outcomes would consist of randomized controlled trials that compare outcomes in patients managed with and without nutrient/nutritional panel testing. In the absence of direct evidence, a chain of evidence can be examined. Nutrient/nutritional panel tests are specifically targeted at patients with mood disorders, fibromyalgia, and chronic fatigue so that this review will focus on those conditions. The following is a summary of the key literature.

Nutrient/Nutritional Panel Testing

Clinical Context and Test Purpose
The purpose of nutrient/nutritional panel testing in patients who have mood disorders, fibromyalgia, or unexplained fatigue or in healthy individuals seeking to optimize health and fitness is to inform a decision whether the patient might benefit from specific nutrient supplementation.

The question addressed in this policy is: Does nutrient/nutritional panel testing, to identify nutrient deficiencies, result in improved health outcomes among patients with mood disorders, fibromyalgia, or unexplained fatigue or among healthy individuals seeking to optimize health and fitness compared with standard of care.

The following PICOTS were used to select literature to inform this review.

Patients
The relevant populations of interest are patients with mood disorders, fibromyalgia, or unexplained fatigue, or healthy individuals seeking to optimize health and fitness.

Interventions
The relevant intervention of interest is nutrient/nutritional panel testing.

Comparators
The relevant comparator of interest is standard of care.

Outcomes
The potential beneficial outcomes of primary interest would be an improvement in symptoms, change in disease status, and functional outcomes. The potential harmful outcomes are those resulting from a false test result. False-positive or false-negative test results can lead to the initiation of unnecessary treatment and adverse events from that overtreatment or undertreatment.

Timing
Nutrient/nutritional panel testing might be conducted before or after starting specific therapy for the specific conditions addressed herein or as a screening test for healthy individuals seeking to optimize health and fitness.

Setting
Ordering and interpreting nutrient/nutritional panel testing should be done by physicians in an outpatient or inpatient setting.

Technically Reliable
Assessment of technical reliability focuses on specific tests and operators and requires review of unpublished and often proprietary information. Review of specific tests, operators, and unpublished data are outside the scope of this policy and alternative sources exist. This policy focuses on the clinical validity and clinical utility.

Clinically Valid
Evidence to support the clinical validity of nutrient/nutritional panel testing would require studies that report the sensitivity, specificity, and positive and negative predictive values of these tests in detecting nutritional deficiency compared with a criterion standard test, preferably among the study population of interest. Currently, there is no literature reporting on the clinical validity of nutrient/nutritional panel tests in this target population.

Clinically Useful
The chain of evidence to support the clinical utility of the use of nutrient/nutritional panel testing would consist of: (1) evidence that specific nutritional deficiencies included in the panel test are significantly associated with mood disorders, fibromyalgia, and/or chronic fatigue; (2) evidence that, in patients with mood disorders, fibromyalgia, and/or chronic fatigue, treatment of a patient found to have specific nutritional deficiencies (eg, with nutritional supplements) improves health outcomes; and (3) evidence that, if there is sufficient evidence on the first 2 items, panel testing is more appropriate than testing for specific nutrients.

No studies were identified that directly evaluated the impact of nutrient/nutritional panel testing on health outcomes. Evidence for a chain of evidence is examined next.

Mood Disorders, Fibromyalgia, or Unexplained Fatigue
Several systematic reviews and meta-analyses evaluating associations between the indications of interest and specific nutrient deficiencies were identified, and they are described in Table 2. No systematic reviews or meta-analyses were identified on the association between nutritional deficiencies and unexplained fatigue. A limitation of all reviews is that, although they compared low and high levels of nutrient levels, none addressed whether these low levels constituted actual deficiencies in a particular nutrient.

Subsection Summary: Mood Disorders, Fibromyalgia, or Unexplained Fatigue
Evidence from multiple systematic reviews and meta-analyses of observational studies have indicated an association between deficiency of nutrients (vitamin B12, vitamin D, folate, magnesium, zinc) and different outcomes (depression, fibromyalgia). There is no evidence whether screening for these nutrient deficiencies results in improved health outcome compared with no screening.

Treatment of Mood Disorders, Fibromyalgia, or Unexplained Fatigue in Patients With Nutritional Deficiencies
Several systematic reviews and meta-analyses evaluating health outcomes in patients with depression treated with nutritional supplementation were identified, and they are described in Table 3. A limitation of all of the reviews is that they did not require patients to have an established deficiency of any nutrient. No systematic reviews or meta-analyses were identified on nutritional interventions in patients with fibromyalgia or unexplained fatigue.

CI: confidence interval; HDRS: Hamilton Depression Rating Scale; MD: mean difference; RCT: randomized controlled trial; SMD: standard mean difference.

Nowak et al (2016) conducted a single-center, double-blind, placebo-controlled trial to determine whether a single vitamin D dose would reduce fatigue after 30 days among 120 otherwise healthy persons with low serum 25-hydroxyvitamin D (25(OH)D) levels (mean age, 29 years; 53% women).10 The outcome was measured using the Fatigue Assessment Scale. The vitamin D group had a significantly greater decrease in mean (standard deviation [SD]) Fatigue Assessment Scale score (-3.3, SD=5.3) than the placebo group (-0.8, SD=5.3; p=0.01). Improvements were reported more frequently in the vitamin D group (42 [72%]) than in placebo group (31 [50%]; p=0.01; odds ratio, 2.63; 95% confidence interval for odds ratio, 1.23 to 5.62). Among all participants, improvement in Fatigue Assessment Scale correlated with the rise in 25(OH)D levels (r=0.22, p=0.02).

Subsection Summary: Treatment of Mood Disorders, Fibromyalgia, or Unexplained Fatigue in Patients With Nutritional Deficiencies
A systematic review and meta-analysis of randomized controlled trials have suggested that folate might have a role as a supplement to other therapies. However, it is unclear whether folate supplement would benefit both people with normal folate level and those with folate deficiency. A meta-analysis of randomized controlled trials has suggested no significant benefit of vitamin D supplementation vs placebo in the case of depression. There is no evidence whether screening for these nutrient deficiencies (vs no screening) would result in significant improvement in outcomes.

Panel Testing vs Testing for Individual Nutrients
There is no evidence on any indication to suggest that nutritional panel testing improves the net health outcome compared with testing for one or several individual nutrients. This includes patients with mood disorders, fibromyalgia, and/or unexplained fatigue, as well as healthy individuals seeking to optimize health and/or fitness. Moreover, with nutritional panel testing, there is a potential for incidental findings that could cause harm. Examples of potential harms include unnecessary confirmatory tests, unnecessary treatments provided for clinically insignificant conditions, and toxicity related to supplementation, or interactions between nutritional supplements and prescription medication.

Summary of Evidence
For individuals who have mood disorders, fibromyalgia, or unexplained fatigue, or healthy individuals who seek to optimize health and fitness who receive nutritional panel testing, the evidence includes several systematic reviews on the association between a single condition and a single nutrient and on the treatment of specific conditions with nutritional supplements. Relevant outcomes are symptoms, change in disease status, and functional outcomes. There was no evidence of associations between fibromyalgia or unexplained fatigue and nutrient deficiencies. Systematic reviews have found statistically significant associations between depression and levels of several nutrients; however, there is no evidence that nutrient supplementation for patients with depression improves health outcomes. Also, there is no direct evidence on the health benefits of nutritional panel testing for any condition, including testing healthy individuals, and no evidence that nutritional panel testing is superior to testing for individual nutrients for any condition. The evidence is insufficient to determine the effects of the technology on health outcomes.

Supplemental Information

Practice Guidelines and Position Statements
No guidelines or statements were identified.

U.S. Preventive Services Task Force Recommendations
The U.S. Preventive Services Task Force has not addressed nutritional panel testing. The Task Force has made several recommendations addressing screening for individual nutrients. The Task Force concluded that there is insufficient evidence to recommend for or against screening for iron deficiency anemia in asymptomatic children and vitamin D deficiency in asymptomatic adults.11,12 Screening for iron deficiency anemia is recommended in pregnant women.

Ongoing and Unpublished Clinical Trials
A search of ClinicalTrials.gov in November 2017 did not identify any ongoing or unpublished trials that would likely influence this review.]

Horizon BCBSNJ Medical Policy Development Process:

This Horizon BCBSNJ Medical Policy (the “Medical Policy”) has been developed by Horizon BCBSNJ’s Medical Policy Committee (the “Committee”) consistent with generally accepted standards of medical practice, and reflects Horizon BCBSNJ’s view of the subject health care services, supplies or procedures, and in what circumstances they are deemed to be medically necessary or experimental/ investigational in nature. This Medical Policy also considers whether and to what degree the subject health care services, supplies or procedures are clinically appropriate, in terms of type, frequency, extent, site and duration and if they are considered effective for the illnesses, injuries or diseases discussed. Where relevant, this Medical Policy considers whether the subject health care services, supplies or procedures are being requested primarily for the convenience of the covered person or the health care provider. It may also consider whether the services, supplies or procedures are more costly than an alternative service or sequence of services, supplies or procedures that are at least as likely to produce equivalent therapeutic or diagnostic results as to the diagnosis or treatment of the relevant illness, injury or disease. In reaching its conclusion regarding what it considers to be the generally accepted standards of medical practice, the Committee reviews and considers the following: all credible scientific evidence published in peer-reviewed medical literature generally recognized by the relevant medical community, physician and health care provider specialty society recommendations, the views of physicians and health care providers practicing in relevant clinical areas (including, but not limited to, the prevailing opinion within the appropriate specialty) and any other relevant factor as determined by applicable State and Federal laws and regulations.
