# Best Lab Testing Companies for Med Spas (2026)

**In short:** A buyer list for med spa owners adding lab testing: eight companies compared on whether your medical director or the company's providers order, whether clients can collect during a clinic visit, whose name is on the results, and how labs connect to hormone and weight-loss programs.

Last reviewed 2026-11-09 · Written by Chad H.

## Key takeaways

- For a med spa, the first decision is whether the medical director's license carries the lab orders (Evexia Diagnostics, Vibrant Wellness, or Getlabs for home draws) or the vendor's own clinicians order them (Analyte Health, Choose Health, Karpa Health, OpenLoop, SiPhox Health).
- Choose Health says clients can collect its kits in the partner's clinic. Evexia Diagnostics, Getlabs and Vibrant Wellness offer mobile phlebotomists, and Karpa Health uses Labcorp patient service centers.
- Analyte Health, Karpa Health and OpenLoop can run lab testing and prescription programs such as hormones and GLP-1 weight loss under one med spa brand, which lets a baseline panel lead into a program the spa already sells.
- Karpa Health does not suit a med spa whose medical director must sign every order, that wants a clinician to review every result, or that sells mostly DUTCH, Genova or other specialty kits.

## Questions this page answers

**What is the best lab testing company for a med spa?**

The answer turns on your medical director. If they will order tests under their own license, look at Evexia Diagnostics or Vibrant Wellness, and add Getlabs if clients want blood drawn at home. If you would rather the vendor's clinicians order under your spa's brand, compare Analyte Health, Choose Health, Karpa Health, OpenLoop and SiPhox Health. Karpa publishes this guide, so confirm details on each company's site.

**Does our med spa's medical director have to order the lab tests?**

No, not with every vendor. Analyte Health's terms have an independent licensed clinician submit or decline each requisition, Choose Health processes physician requisitions for its kits, Karpa Health's independent provider network orders every test, OpenLoop's clinicians order and review results, and SiPhox Health's physicians issue requisitions. With Evexia Diagnostics and Vibrant Wellness, the order comes from your own licensed provider.

**Can clients give a sample during their appointment at the spa?**

Choose Health says patients can collect its finger-prick or Tasso kits in the partner's clinic. Getlabs, Evexia Diagnostics and Vibrant Wellness can send a mobile phlebotomist. Karpa Health uses Labcorp patient service centers, and SiPhox Health's upper-arm kit is designed for home use. If your spa plans to run any test on site, federal CLIA rules require a certificate for the tests performed.

**Can a med spa use lab results to sell a GLP-1 or hormone program?**

A baseline panel is a common first step before a clinician decides on a program, and three vendors here run both under one brand. Analyte Health offers consults through a partnered medical group with optional pharmacy fulfillment, Karpa Health adds TRT, HRT, GLP-1 weight loss and peptide programs from $297 a month plus a one-time implementation fee, and OpenLoop connects labs to its hormone and medical weight loss programs. The prescribing decision stays with the clinician.

**Who sets the price clients pay for lab tests at a med spa?**

On Choose Health, Karpa Health and SiPhox Health the spa sets the retail price, and Evexia Diagnostics' Client Bill option (part of its $50-a-year EvexiaComplete tier) lets the practice bill clients its own price. Vibrant Wellness lets practices set their own patient prices outside New York, New Jersey, California and Rhode Island. OpenLoop charges patients itself as merchant of record. Analyte Health does not publish who sets the price for partner customers.

---

The best lab testing company for a med spa depends on who signs the orders. If your medical director will order under their own license, Evexia Diagnostics and Vibrant Wellness fit, with Getlabs for home draws. If the vendor's clinicians should order under your spa's brand, compare Analyte Health, Choose Health, Karpa Health, OpenLoop and SiPhox Health.

**Disclosure:** Karpa Health wrote this list and appears in it. The eight companies run in alphabetical order, which implies no ranking. We took each competitor fact from its own website, documentation or press coverage in November 2026 and flag anything a company does not publish. Check each vendor directly before signing. Our [white label lab testing companies](/compare/best-white-label-lab-testing-companies/) list covers the wider market.

## Why Do Med Spas Add Lab Testing?

Most med spas already sell services where lab values matter: hormone therapy, medical weight loss, peptides and IV therapy. A lab offer gives clients a reason to book before a program starts, and gives the spa a repeat visit when they retest. Aesthetic-only clients may also buy a wellness panel as an add-on, especially when it carries the spa's name.

Three things decide which vendor fits:

- **Your medical director's role.** A spa owner without a clinical license cannot order tests. Either your medical director or another licensed prescriber orders, or the vendor's own clinicians do. Some medical directors want every order under their name; others prefer to stay out of routine lab orders. Our guide on [who can order lab tests](/resources/who-can-order-lab-tests/) explains the rules.
- **Where the client gives the sample.** A Labcorp or partner draw site, a phlebotomist at the client's home, a kit at home, or a kit done in your treatment room. If you plan to run tests in the spa itself, see [whether you need a CLIA waiver](/resources/clia-waiver-to-sell-lab-tests/).
- **What happens after the result.** Whether a clinician reviews it, and whether a hormone or weight-loss program can follow under your brand.

## The Eight Companies, Alphabetically

### Analyte Health: Labs, Consults and Pharmacy for Aesthetics and Wellness Brands

Analyte Health names med spas, IV therapy and vitamin infusion clinics in its target audience. It runs the consumer testing sites STDcheck.com and HealthLabs.com and has been owned by Brightstar Capital Partners since August 2025.

**For a med spa:** your medical director does not sign the lab orders, because Analyte's terms have an independent licensed clinician submit or decline each requisition. The draw for spa clients is where Analyte publishes the least: it describes 4,500 CLIA-certified lab locations, and its consumer site STDcheck.com names Quest and LabCorp, but partner collection steps are not described. The bigger draw for a spa is the program side. Consults come from MD, NP or DO clinicians through a partnered medical group, with optional pharmacy fulfillment in categories including weight loss and GLP-1, testosterone, peptides, hair loss and dermatology. Pricing, who sets the client price and where payments land are handled through Analyte's partnership form. See [Karpa vs. Analyte Health](/compare/karpa-vs-analyte-health/).

### Choose Health: Kits a Client Can Do in Your Treatment Room

Choose Health includes med spas and weight loss facilities in the businesses it serves, and says patients can collect its kits in the partner's clinic as well as at home.

**For a med spa:** that matters if your front desk wants to sell a panel during a facial or injectable appointment. The client uses a finger-prick card or a Tasso arm device, and the kit goes back in a prepaid mailer; Choose Health says arm-collection results usually come back within 3 days of mailing. Panels are built from about 100 biomarkers covering hormones, thyroid, liver, kidney and metabolic health, which lines up with hormone and weight-loss intake. Box, emails and results dashboard carry your brand. Choose Health's physicians handle the requisitions (the group is not named), so your medical director stays out of routine orders. Wholesale terms are set with its sales team, and it does not describe a partner storefront, so you sell the kit through your own booking or retail system. Most partners launch in 2 to 6 weeks, per Choose Health. See [Karpa vs. Choose Health](/compare/karpa-vs-choose-health/).

### Evexia Diagnostics: For a Medical Director Who Wants Every Order

Evexia Diagnostics gives a licensed clinician one account for Labcorp panels plus more than 200 specialty kit tests from 30+ labs, including Precision Analytical (DUTCH) and Genova Diagnostics.

**For a med spa:** this suits a spa whose medical director or nurse practitioner wants to choose tests client by client, for example a DUTCH hormone panel before starting HRT. With Client Bill, the spa pays Evexia per test and bills the client its own price. Clients draw at a Labcorp patient service center ($10 per specimen) or with one of 6,000+ mobile phlebotomists, which can mean a draw at the spa. A non-licensed staff member can order through Evexia's internal physician network, outside New York, New Jersey and Rhode Island, though those physicians only facilitate ordering. Evexia has no white label storefront and does not publish a prescription program, so the spa's own clinicians handle any treatment. Test prices appear after you create a free account. See [Karpa vs. Evexia](/compare/karpa-vs-evexia/).

### Getlabs: A Phlebotomist Sent to Your Client

Getlabs is a mobile phlebotomy company, not a lab or ordering service. Its W-2 phlebotomists draw blood at a home or office and deliver the sample to Labcorp, Quest, a specialty lab or your chosen lab.

**For a med spa:** Getlabs fits when your medical director already orders labs and your clients would pay for a concierge draw. You need your own lab account, because the lab bills the testing separately and Getlabs only charges for the visit, which you can absorb or pass on. Scheduling links are co-branded with Getlabs. Service covers 34 states plus Washington DC, so check every location if you run more than one spa. Function Health completed its purchase of Getlabs in April 2026. See [Karpa vs. Getlabs](/compare/karpa-vs-getlabs/).

### Karpa Health: A Branded Lab Menu That Can Lead Into Programs

Karpa Health runs Labcorp testing under the spa's name, as a ready-made lab storefront, a white-label checkout and patient portal on the spa's website, or an API.

**For a med spa:** a licensed provider in Karpa's independent network orders each test, so your medical director's license is not involved and labs-only does not need LegitScript certification. Clients go to a Labcorp patient service center for the draw today, and branded at-home kits, including white-labeled Tasso devices above a minimum order quantity, start December 1, 2026. You choose the price, the money settles to the spa's own Stripe account, and Karpa adds a $6 collection fee per order. Results go to the client's branded portal and are not reviewed by a provider unless the client books a TRT or HRT consult, so plan who will answer client questions. If a client's panel leads to interest in a program, the same brand can offer TRT, HRT, GLP-1 weight loss and peptide programs from $297 a month plus a one-time implementation fee. Labs-only pricing is shared on a call, and coverage is 47 states plus DC. See the [lab storefront](/solutions/diagnostic-labs/).

### OpenLoop: Results Visits Included, With OpenLoop Taking Payment

OpenLoop is a white label telehealth company whose lab offer includes clinician ordering, results review and 1:1 results visits under the partner's brand.

**For a med spa:** OpenLoop fits a spa that wants every client to hear results from a clinician without using its own staff. Labs connect to OpenLoop programs that include hormones, medical weight loss and dermatology, and its Whole Health Diagnostics membership bundles a 110+ biomarker panel, up to four tests a year and optional personalized supplements. Collection is an at-home kit or a partner lab where available, and the labs are not named. OpenLoop is the merchant of record, so clients pay OpenLoop inside the white label site it runs for you; pricing is quoted by sales.

### SiPhox Health: Retail Kits Sold at the Front Desk

SiPhox Health sells co-branded or white label at-home kits built around its EasyDraw upper-arm device, and lists clinics and longevity and concierge practices among its partners.

**For a med spa:** the model works like retail inventory. You buy kits at wholesale (SiPhox's articles state a 30-kit minimum to start and 500+ kits for full white label and custom panels), then sell them at a price you set, at checkout or online. SiPhox's physicians issue the requisitions, so no one at the spa orders. SiPhox frames its testing as wellness-only and names HRT/TRT and GLP-1 among its clinic use cases, though it publishes no prescription program for partners. Clients collect at home with live support. Kits are not available in Hawaii or New York. See [Karpa vs. SiPhox Health](/compare/karpa-vs-siphox-health/).

### Vibrant Wellness: Specialty Panels Ordered by Your Medical Director

Vibrant Wellness runs its own Zoomer panels in its Santa Clara labs and sells only to licensed providers.

**For a med spa:** your medical director or NP orders in Vibrant's portal, and its terms require them to confirm state law lets them order each test. The Hormone, Nutrient and Gut Zoomers line up with hormone and wellness programs. Kits ship to the client within 24 hours, or blood is drawn through its network of 2,000+ draw sites and mobile phlebotomists. Clients or the spa pay Vibrant, and the spa can set its own patient prices, with its share credited to Vibrant's Wallet and paid out to your bank, except in New York, New Jersey, California and Rhode Island, where prices cannot be adjusted. You can put the spa's logo on the patient portal; Vibrant has no published white label program. See [Karpa vs. Vibrant Wellness](/compare/karpa-vs-vibrant-wellness/).

## Questions to Ask Each Vendor Before You Sign

1. Whose license is on the requisition, and does my medical director need to sign or supervise anything?
2. Can a client give a sample in my spa, and if so, who supplies the kit or phlebotomist?
3. Who reviews abnormal results, and who contacts the client?
4. Whose name appears on the checkout, the receipt and the results report?
5. Do I set the price, and does the money settle to my account or the vendor's?
6. Can results flow into a hormone, weight-loss or peptide program under my brand, and who prescribes?
7. Is every state where I have a location covered?

## A Worked Example: A Pre-Program Panel

Say your spa sells medical weight loss and wants a baseline panel before a client's first consult.

1. **Pick the panel.** Let the clinician who will prescribe set the biomarker list, so the panel answers the questions they ask at intake.
2. **Decide who orders.** If your medical director orders, Evexia Diagnostics or Vibrant Wellness. If you want the vendor to order, Analyte Health, Choose Health, Karpa Health, OpenLoop or SiPhox Health.
3. **Decide where the sample happens.** In the treatment room (Choose Health), at a lab (Evexia Diagnostics, Karpa Health, Vibrant Wellness), at home by kit (Choose Health, OpenLoop, SiPhox Health) or by phlebotomist (Evexia Diagnostics, Getlabs, Vibrant Wellness).
4. **Price it.** Your margin per panel is your retail price minus the vendor's cost, any collection fee (for example, Karpa's $6 per order or Evexia's $10 per Labcorp specimen) and card processing. Our guide on [how much to charge for lab tests](/resources/how-much-to-charge-for-lab-tests/) walks through the math.
5. **Plan the handoff.** Decide whether the client books the program consult before or after results arrive, and who explains the numbers.

## When Karpa Is the Right Fit, and When It Is Not

Karpa Health fits a med spa that wants a Labcorp lab menu under its own name, ordered by Karpa's provider network rather than the medical director, priced by the spa and paid into the spa's Stripe account, with hormone, GLP-1 and peptide programs available under the same brand when the spa is ready.

Karpa Health is not the right fit when:

- **Your medical director insists on ordering every test.** Karpa's network orders on Karpa. Evexia Diagnostics and Vibrant Wellness run on your own provider's orders.
- **Every client should hear results from a clinician.** Karpa's provider reviews results only when a client books a TRT or HRT consult. OpenLoop includes results visits.
- **You want clients to collect in the spa today.** Karpa uses Labcorp draws now, with at-home kits from December 1, 2026. Choose Health supports in-clinic kit collection, and Evexia's mobile phlebotomists can draw at an office.
- **Your hormone work depends on DUTCH or Genova panels.** Karpa runs Labcorp tests only. Evexia Diagnostics lists those labs, and Vibrant Wellness runs its own specialty panels.
- **A spa location is in Hawaii, Maine or North Dakota.** Labcorp has no patient service center in those states, so Karpa does not operate there.
- **You need to see labs-only storefront pricing before talking to anyone.** Karpa quotes it on a call.

## How to Choose

Ask your medical director first whether they want to sign lab orders. A yes points to Evexia Diagnostics or Vibrant Wellness, with Getlabs for home draws. A no points to Analyte Health, Choose Health, Karpa Health, OpenLoop and SiPhox Health; from there, choose on where clients give the sample and whether you want labs to lead into programs under your brand.
