How to Add Whole-Health Diagnostics to Your Medspa: A Step-by-Step Guide
Learn how to build a diagnostic testing program that connects client insights with more informed, ongoing care.
Your clients are already coming to you for improved wellness, not just a single treatment. They're booking facials for skin health, injectables for confidence, and increasingly asking about weight, hormones, and aging along the way. The opportunity for medspas is to meet that broader interest with data, not just another service on the menu.
Diagnostics can help bridge the gap between appointments by turning testing into an ongoing touchpoint. With real client data to inform care, patients gain a clearer view of what's actually driving their skin, weight, or energy concerns.
But diagnostic testing today extends well beyond a single lab order. From at-home testing to ongoing monitoring and integrated results, the options for bringing diagnostics into a medspa's existing service menu continue to expand.
If you're exploring how to add whole-health diagnostics to your medspa, this guide walks through eight high-level steps for building a program designed to fit seamlessly into your medspa's existing workflows.
What is diagnostic testing?
Whole-health diagnostics takes a broader look at a client's health rather than focusing exclusively on a single symptom or concern.
Depending on the client, clinical context, and services your medspa is equipped to support, testing may include areas such as:
Metabolic health: glucose, cholesterol, and other metabolic biomarkers
Hormone health: thyroid and other hormone-related markers
Micronutrients: vitamin D, B12, iron, and other commonly evaluated nutrients
Cardiovascular health: lipid testing and other relevant cardiovascular risk markers
Recovery and wellness: testing or monitoring that may provide additional context around sleep, recovery, and overall health
The broader movement behind this approach isn't simply about generating more data. It's about giving clients and clinicians information that can help support more informed conversations about health.
Clients are asking for more health data
Demand for diagnostics is growing alongside a broader shift toward more proactive and personalized care.
According to Grand View Research, the global clinical diagnostics market was valued at $115.5 billion in 2024 and is projected to reach $169.2 billion by 2030. Growth is being driven by rising rates of chronic disease, an aging population, greater demand for personalized medicine, and increased patient awareness around disease diagnosis.

For medspas, the takeaway is straightforward: clients increasingly want more information about their health and more convenient ways to access it.
Where whole-health diagnostics fits into your business
Where diagnostics fits into the care you already provide
Adding diagnostics to your clinic doesn't mean creating an entirely new service line.
Instead, testing can strengthen the services already on your menu by giving clinicians and clients another source of information for treatment planning and follow-up.
Diagnostics can help your business support:
Establishing a baseline before starting a new treatment or wellness program
Identifying hormone or metabolic factors behind skin, weight, or energy concerns
Informing nutrition or lifestyle recommendations that complement in-office treatments
Monitoring progress across a longer-term program over time
Supporting membership or package renewals with data that shows real change
This is where whole-health diagnostics become particularly valuable for business models that are limited to treatment rooms and provider hours.
Instead of the client relationship ending when they walk out the door, testing creates another meaningful touchpoint between the client and their care team. Building those capabilities in-house can require additional workflows, technology and team resources to coordinate testing and follow-up. Working with a white-label diagnostics partner can help take on much of that operational lift while allowing you to keep the experience under your brand.
Common types of diagnostic panels
Several categories commonly appear in medspa wellness and diagnostic programs.
Comprehensive metabolic testing
Testing may include markers such as glucose, HbA1c, fasting insulin, and other measures related to metabolic function, often used to support weight and body-composition programs.
Hormone and thyroid testing
Depending on clinical appropriateness, panels may evaluate markers such as TSH, cortisol, and sex hormones, all of which can influence skin quality, weight, and energy, some of the most common concerns clients bring to a medspa.
Cardiovascular and inflammation markers
These panels may include lipids, hsCRP, and other markers clinicians can use when evaluating cardiovascular or inflammatory risk, which is increasingly relevant as medspas expand into longevity and whole-health programs.
General wellness testing
Depending on the program, medspas may also consider testing biomarkers such as vitamin D and B12 alongside other general wellness markers, a natural fit for clients already asking about IV therapy or supplement add-ons.
Additional screening
STI testing, urinalysis, and other screening services may also be appropriate depending on the population you serve and the clinical structure of your program.
How to add whole-health diagnostics to your medspa
1. Identify what your clients actually need
Start with the needs already appearing in your client population.
Review:
Common client questions
Existing services and care pathways
Gaps in your current offerings
Areas where additional health information could support care decisions
Opportunities for appropriate follow-up or monitoring
This exercise should help you identify the purpose of your whole-health diagnostics program before you select individual tests.
A medspa looking to support metabolic health may need a very different testing strategy than one focused on hormones, preventive wellness, or cardiovascular risk.
Start with the problem you're trying to solve. Build the testing menu around it.
2. Choose the right diagnostic panels
Once you've defined the program's purpose, determine which tests support it. Depending on your client population and care model, there are several health diagnostics you may want to consider, including:
Comprehensive bloodwork
Metabolic testing
Hormone and thyroid testing
Cardiovascular markers
Inflammation markers
Nutritional biomarkers
STI testing and urinalysis, when appropriate
Resist the temptation to launch with an enormous menu.
A smaller number of clearly defined panels is often easier to explain, operate, and measure. Additional testing can be introduced as client demand and clinical needs become clearer.
3. Identify your diagnostic collection type
Next, determine how specimens will be collected.
Options may include:
National laboratory locations
Mobile phlebotomy
On-site collection
Your model may use more than one option.
When evaluating each approach, consider convenience, geographic availability, cost, specimen requirements, client preferences, and the operational impact on your staff.
The best collection strategy is one that fits naturally into the client journey without creating unnecessary friction for clients or your team.
4. Establish provider oversight and clinical support
Diagnostics is a clinical service, which means oversight and clinical support need to be part of the infrastructure from the beginning.
Determine:
Who has authority to order testing
Who reviews results
How abnormal findings are escalated
Which licensure requirements apply
How client consent is documented
How health information is stored and transmitted
How results and follow-up communication are documented
If your program reaches members across multiple states, clinician must be licensed in the state the patient is requesting care. This can lead to state specific licensure and credentialing complexities.
5. Build the clinical protocols behind the tests
Ordering the test is only one part of the program.
Before launch, define what happens before and after that order.
Your protocols should address areas such as:
Client eligibility
Test-selection criteria
Ordering workflows
Result review
Abnormal-result escalation
Follow-up recommendations
Retesting intervals
Documentation requirements
Standardization matters because it helps your team deliver a more consistent experience as testing volume grows.
It’s important to build a repeatable pathway your clinicians and staff can follow.
6. Design the complete client journey
Now map the experience from the client's perspective.
A typical pathway might look like:
Intake → clinician recommendation → Lab order → Specimen collection → Results → Clinician review → Next step → Follow-up or retesting
Look for friction at every stage. Ask yourself:
Can clients easily understand which test they need?
Do they know where to go?
Can they access their results easily?
Will someone explain what those results mean?
Do they know what happens next?
Strong diagnostics programs don't leave those questions unanswered.
Your client experience should connect every step into one clear journey.
7. Connect results to actionable care
A lab result shouldn't be the end of the experience.
Diagnostics can help uncover opportunities for more personalized care based on a client's results, goals, and clinical needs. Appropriate next steps could include:
Nutrition or lifestyle interventions
Ongoing wellness support
Clinician follow-up
Additional testing or monitoring
Medication when clinically appropriate
Enrollment in a more comprehensive or personalized care program
The specific path will differ from client to client— what's important is having a clear process for turning diagnostic insights into relevant next steps and ongoing care.
8. Launch, measure, and expand
You don't need to launch every possible panel on day one.
Start with a focused program, measure how it performs, and expand based on real client and operational data.
Consider tracking:
Test utilization
Client engagement
Test completion rates
Follow-up rates
Operational efficiency
Relevant clinical outcomes
These metrics can show where the client journey is working and where additional support may be needed.
As demand grows, you can evaluate additional panels, collection methods, and complementary services.
Build vs. buy: choosing your whole-health diagnostics infrastructure
