Different tests.
Different views into your biology.
From metabolic biomarkers to cellular response to comprehensive nutritional analysis, Chemistry at Work™ gives organizations different ways to bring private, personal laboratory information to employees.
Personal insight. Private results. A deeper view of individual biology.
Three different ways to look at your nutritional picture.
From metabolic biomarkers to cellular response to comprehensive nutritional analysis, each approach examines different laboratory measurements or responses relevant to nutritional assessment.
chemistry your
metabolism leaves behind.
Screening Option 1
Metabolic Nutritional Assessment
See what your metabolism can reveal.
This option measures metabolites associated with nutrient-related biochemical pathways, providing information for an individualized nutritional review.
Instead of asking only what nutrients are present, it examines the chemical footprints created as metabolism does its work, providing another view of an individual's nutritional picture.
Measurements and Areas of Interpretation
Nutritional Insights
Metabolic indicators associated with B1, B2, B3, B6, B7, B9 & B12
Antioxidant-related interpretation
Indirect mineral-related interpretation: magnesium, manganese, molybdenum & zinc
Amino acids
Laboratory nutritional interpretation for professional review
Metabolic Insights
Metabolites associated with energy pathways
Neurotransmitter-related metabolites
Oxidative-stress-related biomarkers
Digestive- and microbial-associated metabolites
Metabolites associated with methylation and glutathione pathways
Many nutrient interpretations are indirect, rather than measurements of vitamin or mineral concentrations. These findings do not, by themselves, establish a deficiency, brain neurotransmitter levels, or overall methylation or detoxification capacity. Interpretation considers health history, diet, medications and other findings; additional testing may be appropriate. Exact coverage depends on the ordered panel.
Testing availability: Metabolic Nutritional Assessment is unavailable in NY, NJ, and RI.

Available through separate assessments where offered; these are not measurements included in the core Metabolic Nutritional Assessment.

Other nutrient-related interpretation
The laboratory may use metabolic and amino-acid patterns to generate nutritional interpretations involving antioxidants (including vitamins C and E, vitamin A/carotenoids, glutathione, lipoic acid and coenzyme Q10) and minerals (magnesium, manganese, molybdenum and zinc). These interpretations are indirect, are not confirmed deficiencies, and require professional review in context.
Specific markers and collection requirements are subject to the ordered panel. Fatty-acid profiling and expanded elemental testing are not assumed to be part of this standard assessment. Cortisol and sleep-related assessments, where offered, are separate add-ons.
Screening Option 2
Cellular Functional Assessment
Explore how your cells
respond in the laboratory.
This assessment examines immune-cell growth responses under controlled laboratory conditions with individual nutrients and related compounds.
This screening option evaluates laboratory cellular responses across a 55-item panel of nutrients and related compounds. Results provide additional information to discuss with an appropriate healthcare professional.
Measurements and Areas of Interpretation
Nutritional Insights
B vitamins: B1, B2, B3, B5, B6, B7, B9, B12
Vitamins A, C, D, E & K
Minerals & trace elements
Amino acids
Antioxidants & other nutrients
Cellular Responses
Cellular micronutrient responses
Immune-cell growth responses
Laboratory cellular redox responses*
Laboratory oxidative-stress responses*
Laboratory antioxidant responses*
Measures immune-cell responses in the laboratory, not blood nutrient concentrations. A laboratory response alone does not establish a whole-body nutrient deficiency or demonstrate that supplementation will improve health. *Redox and antioxidant-response assessments depend on the ordered package.
The laboratory measures how well immune cells reproduce under controlled conditions and whether individual nutrients improve that response.

The full panel combines urine-based metabolic markers with blood-based components. Genetic variants and vitamin D may be available as separately ordered add-ons; they are not represented as standard included measurements. Exact coverage varies with the ordered version and collection method.

Compare collection approach, primary insight area, privacy, and follow-up options.
Help employees understand what comes next.
Screening can be paired with independent professional support so employees can better understand their results, identify appropriate follow-up, and decide what questions to bring to their own healthcare providers.
Dietitian Guidance
Participants book directly with a registered dietitian through the program portal, may choose to share their results, and use insurance where applicable or self-pay.
Follow-Up
Preliminary findings can be reviewed with an appropriate professional and, when needed, verified through additional testing before treatment decisions.
Retesting Options
Follow-up screening can be incorporated where appropriate to give employees another point of reference over time.
Individual screening results stay private.
Chemistry at Work™ is structured so employers can sponsor screening and education without receiving or managing an employee's individual screening results.
Individual screening results are delivered to the participant through the appropriate testing or provider pathway.
Employers do not receive an employee's individual laboratory or screening results through Chemistry at Work.
Good Health Geek coordinates program delivery and does not receive individual screening results. Results remain with participants and their testing providers.
Simple for the employer. Private for the employee.
The selected screening pathway can be integrated into the Chemistry at Work™ rollout without requiring HR to handle individual screening information.
Choose the Screening Path
Select Screening Option 1, 2, 3, 4, or the approved combination that best fits the organization.
Employees Receive Access
Participants receive the appropriate ordering, collection, or kit instructions.
Private Testing
Samples are collected and processed through the selected testing provider.
Employee-Directed Next Steps
Employees receive their individual results through the applicable provider pathway and can access appropriate follow-up resources.
Common Questions
Does every employee have to use the same testing option?
Screening pathways are chosen by the employer. All participating employees receive the same screening pathway.
Does Good Health Geek receive employee test results?
No. Individual results are delivered to participants through the applicable laboratory or provider pathway. Good Health Geek does not receive individual results.
Does the employer receive individual results?
No. Chemistry at Work™ is designed around employee privacy. Individual screening information is not provided to the employer.
Can employees be tested again later?
Retesting can be incorporated where appropriate. For example, an employer program may include a follow-up screening several months after the initial test.
Is professional support available?
Yes. Participants access registered dietitian networks through the program portal and book directly with a provider. Appointments are billed separately through insurance or self-pay. The provider confirms network participation and coverage before the visit. Participants may choose to share their testing results with their dietitian for individualized nutrition guidance.
