Updates for the Elemental Analysis Profile

We've Updated the Collection Process for Elements

The Elemental Analysis Profile is changing. The table below outlines the specimen matrix updates. Additionally, the collection process is being simplified. See the below corresponding box descriptions and instructions for more details.

New Collection Process LabelWe have created a collection update reminder label for Elemental Analysis collection boxes. When you see the reminder label, simply follow the collection process instructions included within the labeled box.

If you DO NOT see the update reminder label on your Elemental Analysis box, follow the collection process included within that test box.

Specimen-Matrix Updates

Elemental Markers are currently measured in red blood cells (RBCs) specimen matrix. The updated collection process is part of a change to this specimen matrix.

For the complete details on these enhancements, view the linked Specimen-Matrix Updates.

If you have questions regarding this change or what it means for your patients, please contact us at 800.522.4762 to speak with one of our Client Services Representatives.

Important Updates to NutrEval®

We've Updated the Collection Process and Designed New NutrEval® Boxes

Redesigned NutrEval BoxUpdated blood collection and processing steps will be implemented for our NutrEval family of testing. To facilitate this update, we have designed a new NutrEval box.

The collection process will be aligned with the NutrEval package you are using. This update is reflected in the following tests:

  • NutrEval® FMV
  • NutrEval® Plasma Amino Acids

Collection Process Corresponds to your NutrEval Box Design

Old NutrEval Box If you're using our original NutrEval FMV or Plasma box design, use the collection process detailed on the instructions included within the box.


Redesigned NutrEval Box If you're using our new NutrEval FMV or Plasma box design, use the NEW collection process detailed on the instructions included within the box.

Elemental Markers are currently measured in red blood cells (RBCs) specimen matrix. The updated collection process is part of a change to this specimen matrix. Additionally CoQ10 will be measured in serum.

Highlights of these changes are shown at the Specimen-Matrix Updates link below.

January 2017

Important Information Related to Salivary Cortisol Testing

Effective January 16, 2017, due to a vendor change, we will begin measuring salivary cortisol using Salimetrics Salivary Cortisol Immunoassay Kit (EIA). Per the FDA, this kit is for in vitro diagnostic use. The diurnal pattern and clinical interpretation will remain the same; however, reference ranges will change.

Impacted tests include:

  • Adrenocortex Stress Profile
  • Menopause Plus
  • One Day Hormone Check
  • Rhythm Plus
  • Male Hormones Plus
  • Salivary Cortisol (this is a stand-alone test)

The diurnal pattern depicted on our report graphics will remain exactly the same. Values that are below the detection limit of the assay will be reported as: < 0.007. The reference ranges will change and are based on a healthy cohort of individuals with normal diurnal cortisol patterns and DHEA results.

When performing follow-up testing, result comparison can be made by assessing the relative placement of the result value in relation to the reference range for historic and new reporting.

If you have questions regarding this change or what it means for your patients, please contact us at 800.522.4762 to schedule a free consultation with one of our clinicians on staff.

Platform Change for Celiac and Gluten Sensitivity Panel

Effective January 3, 2017, a portion of the Celiac and Gluten Sensitivity Panel will run on a new, more automated platform, Phadia 250. Phadia 250 is an FDA-cleared fluorescence enzyme immunoassay (FEIA). New reference ranges will be provided by the manufacturer, however report algorithms and clinical interpretation of the test will remain the same.

Minor changes to the language and graphics on the Celiac and Gluten Sensitivity Panel will occur. Instead of reporting "weak positive" results, Phadia 250 will report "equivocal" and this result will be represented with a colorimetric change to yellow on the report. "Equivocal" will signify that results fall within the intermediate range and require further investigation. Additionally, the graphic algorithmic tree will also reflect the language change of "equivocal or positive" to represent how to proceed with further work up required for diagnosis.

Please note that the isolated markers of total IgA and the reflex measurement of Anti-EMA are not available on Phadia 250 and will continue to be run using the previous platform.

If you have any questions related to this upgraded platform, please call us at 800.522.4762.

Medicaid of Minnesota and Medicaid of Oregon

Genova Diagnostics will no longer be contracted with Medicaid of Minnesota and Medicaid of Oregon effective 01/15/2017.

The schedule B prices for each test can be found on your laboratory fee schedule and online via our EasyPay Assist Tool.

November 2016

Updated Test Requisition Form

We've redesigned the back of the requisition for easy completion. Notable changes are as follows:

  • The back of the requisition now depicts five easy steps to guide patients through completion.
  • A new section below the patient demographic section has been added to capture employment information for specific states relative to lead reporting in the States of Ohio and New Hampshire. These states now mandate all patients to include information employment data when doing testing that evaluates lead levels.

GI Effects® Kit Instruction Changes

Kit instructions for both One-Day and Three-Day GI Effects® Stool Profiles have been reformatted and will appear in all kits beginning November 22, 2016. Updates include:

  • Reformatted and rewritten instructions to increase ease-of-use and patient compliance
  • New kit tube labels will be utilized to reduce name legibility issues on tubes and decrease rejections
  • Paper surveys have been eliminated; patients are encouraged to visit the Patient Resource Center and complete the online health survey

Amino Acids Discontinuation

In order to provide the highest value testing, we have made the decision to discontinue the Amino Acid Analysis 24 Hour Urine test. Discontinuing tests with very low volume allows us to free up lab equipment and staff that can be used on tests that are in greater demand.

Beginning December 1st, this test will no longer be processed. Kits currently being processed will be completed. Kits received after December 1st will no longer be processed.

We invite you to learn more about our two most popular amino acids tests including Amino Acids Analysis, Plasma, and Amino Acids, Urine. Contact your sales representative for more information.
