Lab tests can be ordered only by people their state authorizes to order them, which in practice means licensed practitioners such as physicians, nurse practitioners and physician assistants acting within their scope of practice. Health coaches, personal trainers, gym owners and med spa owners without a clinical license cannot order lab tests for clients. They can still offer lab testing under their own brand when a licensed provider orders each test.
This guide is for business owners who want to sell lab testing to clients. It covers the federal and state rules, a profession-by-profession table, the states that restrict consumer-ordered testing, where ordering ends and interpreting begins, and the provider-ordered model that keeps a non-licensed business on the right side of all of it. For the full business setup, see our guide on how to start a lab testing business.
Who Is Allowed to Order Lab Tests?
The short answer is whoever state law says, and federal law defers to the states on that point.
Clinical labs in the US operate under CLIA, the federal lab quality rules run by CMS. Under 42 CFR 493.1241, a lab “must have a written or electronic request for patient testing from an authorized person.” The definition of that term in 42 CFR 493.2 is short: “an individual authorized under State law to order tests or receive test results, or both.”
So CLIA sets the requirement that someone authorized orders the test, and each state decides who counts. State lab rules then repeat the point in their own words:
- New York: a clinical lab examines specimens “only at the request of licensed physicians” or other persons authorized by law to use the findings in their practice (10 NYCRR 58-1.7).
- New Jersey: “The laboratory shall examine specimens only at the request of a licensed physician, dentist, or other person authorized by law” (N.J.A.C. 8:44-2.7).
- Rhode Island: “Specimens shall be examined only at the documented request of a licensed physician or other authorized medical personnel” (216-RICR-60-05-4).
Each state’s practice acts then decide which licenses include ordering labs, and for which tests. That is why the honest answer for many professions is “it depends on the state.”
Can My Profession Order Lab Tests? A Table by Role
If you don’t hold a clinical license, you cannot order lab tests on your own authority in any state. If you do, the answer depends on your license, your state and sometimes your practice setting.
| Role | Can they order labs on their own? | What to know |
|---|---|---|
| Health coach | No | No state license to practice medicine. Fullscript’s state-by-state review notes health coaches “don’t have independent ordering rights.” |
| Personal trainer or gym owner | No | A fitness certification carries no authority to order tests. |
| Nutritionist (unlicensed) | No | Same as a health coach. A few states give certain licensed nutrition specialists limited authority, so check your state if you hold a state license. |
| Registered dietitian (RD/RDN) | Varies by state and setting | Typically only where a hospital or institution has granted ordering privileges under state law. Rarely an independent right in private practice. |
| Chiropractor (DC) | Varies by state | Limited to tests within chiropractic scope. Some states allow certain lab tests and others restrict them. |
| Naturopathic doctor (ND) | Varies by state | Only in states that license NDs, such as Oregon, Washington, Arizona and Vermont. In unlicensed states, no. |
| Nurse practitioner (NP) | Yes in full practice states, otherwise with a collaborating or supervising physician | AANP defines full practice as letting NPs “diagnose, order and interpret diagnostic tests.” |
| Physician assistant (PA) | Generally yes, under the supervision or collaboration terms their state requires | Authority runs through the PA’s practice agreement. |
| Pharmacist | Varies by state | Usually only for specific tests under a collaborative practice agreement or state protocol, often for medication monitoring. |
| Med spa owner (unlicensed) | No | Owning the business confers no ordering authority. Orders come from the med spa’s medical director or another licensed prescriber. |
| Esthetician | No | An esthetician license covers cosmetic skin services, not ordering lab tests. |
| Physician (MD/DO) | Yes | Licensed in the patient’s state, within their scope. |
Two practical points sit behind the table.
First, a license is tied to a state. A nurse practitioner licensed in Texas generally cannot order tests for a client who lives in Ohio unless they also hold an Ohio license. Fullscript’s review puts it plainly: “Telehealth lab orders are governed by the laws of the patient’s state, not the provider’s location.”
Second, scope applies test by test. In 2015, New York’s attorney general found that a New York-licensed chiropractor who signed lab requisitions for an online testing company “could not legally order” four of the tests involved: CA 27.29, rheumatoid factor, PSA and tacrolimus (NY AG Assurance of Discontinuance). A license that allows some lab orders does not allow all of them.
If your role is in a “varies” row, your state licensing board is the authority. Don’t rely on a vendor’s summary, including this one.
Can a Health Coach or Personal Trainer Order Blood Work?
No. A health coach or personal trainer cannot order blood work for a client, because neither role is licensed under state law to order lab tests.
That does not mean you can’t offer testing. It means the order has to come from a licensed provider. The usual mistakes in this group are:
- Buying tests in bulk and reselling them through a consumer testing site under your own account, so the client’s order runs through a service meant for individuals ordering for themselves.
- Choosing the tests for each client and presenting the order as your recommendation, which looks like ordering by another name.
- Reading results back to clients and telling them what a number means for their health, covered in the next section.
The compliant version is simple. Your client chooses a test or panel from your storefront, completes an intake, and a licensed provider orders the test. You sell it, brand it and set the price. You don’t order it.
Ordering vs. Reviewing vs. Interpreting: Where the Line Is
Ordering a test, reviewing a result and interpreting it are three different acts, and a non-licensed business owner should do none of them for a client.
Ordering is choosing a test for a specific person and signing the request. In New York, the attorney general’s office treats this as medicine: “Writing prescriptions, including those for laboratory testing, constitutes the practice of medicine” (NY AG). The same document cites New York Education Law § 6512, which prohibits the unauthorized practice of a licensed profession.
Reviewing is looking at a result to decide whether anything needs to happen. When a licensed provider reviews a result, that is clinical work. When a coach looks at a client’s result, the risk is in what the coach says next.
Interpreting is telling someone what a result means for their health, such as “your thyroid is off” or “your testosterone is low, you should start TRT.” That edges into diagnosis, which every state reserves for licensed practitioners.
What a coach or trainer can usually do:
- Talk about general wellness habits, like sleep, training load, protein intake and stress, that apply to anyone.
- Encourage a client to share results with their own doctor or a licensed provider.
- Help the client keep track of when they last tested and when to retest.
What to avoid:
- Labeling a result as normal, abnormal, low or high for that client.
- Recommending a medication, dose or supplement protocol to treat a result.
- Telling a client they don’t need to see a doctor about a result.
Write these limits into your staff scripts, not just your own habits. Your front desk and coaches are the people clients will ask.
Which States Restrict Direct Access Lab Testing?
New York, New Jersey and Rhode Island are the states most often cited as restricting direct access testing, where a consumer orders their own lab test without a practitioner. For a lab business, this matters mainly for one reason: it decides which states you can serve with a model that relies on consumers ordering for themselves.
- New York allows direct access testing only by labs holding a New York permit, and only for tests where an FDA-approved test or collection device is sold over the counter, or a test serving the same purpose, under amendments to the Public Health Law effective September 24, 2002 (Wadsworth Center). Everything else needs an authorized practitioner. The attorney general describes New York law as generally prohibiting direct access testing.
- New Jersey lab rules allow testing only at the request of a licensed physician, dentist or other person authorized by law (N.J.A.C. 8:44-2.7).
- Rhode Island lab rules require the documented request of a licensed physician or other authorized medical personnel (216-RICR-60-05-4).
Beyond those three, the picture is less clear. Lab-testing vendors publish their own lists of states they can’t serve, and those lists disagree, with Massachusetts and Maryland among the states that appear on some lists and not others. Some exclusions also reflect where a lab company has collection sites rather than what the law says. If you plan to serve a specific state, check that state’s lab licensing rules directly or ask counsel.
A provider-ordered model avoids relying on these consumer-ordering rules, because the order comes from a licensed provider rather than the consumer. Practitioner-ordered testing is the default that every state’s lab rules allow. The questions that remain are whether the provider is licensed in the client’s state and whether the test is within their scope.
What Is the Compliant Way to Offer Lab Testing Without a License?
The compliant way is to sell testing under your brand while a licensed provider, licensed in your client’s state, orders each test. You handle the business side. The provider handles the order.
This is how Karpa’s lab storefront for diagnostic labs works:
- Your client buys a test or panel under your brand: on Karpa’s white-label lab storefront, on your own website with Karpa’s lab checkout and patient portal, or in your own app through Karpa’s API.
- The client completes a patient intake form on the storefront.
- A licensed provider in Karpa’s independent network orders the test. You never order, interpret or diagnose.
- The client collects a sample by walking in or booking a time at a Labcorp patient service center (Labcorp runs 2,200+ locations), or, from December 1, 2026, with a branded at-home collection kit.
- The Labcorp report lands in the client’s branded portal.
Some details business owners ask about:
- License and certification. No medical license is needed, and no LegitScript certification is needed for a labs-only brand.
- Where it’s available. 47 states plus Washington DC. It is not available in Hawaii, Maine or North Dakota, because Labcorp has no patient service center there.
- Pricing and payments. You set the retail price, and payments settle to your own Stripe account. Partners typically charge $50 to $200+ per order and aim for around a 50% margin. Our guide on how much to charge for lab tests covers pricing in detail.
- Your dashboard. A partner portal shows revenue, orders, lab results, custom panels and discount codes.
- Results review. Results are not reviewed by a provider by default. A provider looks at them only if the client books a TRT or HRT consult. Plan your client communication around that, and encourage clients to share results with their own clinician.
If you want recurring revenue, starting December 1, 2026, Tasso at-home collection devices can be white-labeled under your brand above a minimum order quantity and sold as a subscription, such as a retest every quarter. And if clients who test their testosterone, thyroid, A1c or lipids want treatment, the same brand can add prescription programs like TRT, HRT or GLP-1 weight loss later, from $297 a month plus a one-time implementation fee, with LegitScript certification at $3,000 through Karpa.
Questions to Ask Any Lab Testing Platform
Whatever platform you use, the order is the part regulators look at. Ask these before you sign:
- Who orders each test? You want a named model: a licensed provider orders every test. If the answer is that you order, or that the client orders through a consumer account you resell, walk away.
- Is the ordering provider licensed in my client’s state? Lab orders follow the patient’s state.
- Is each test within the ordering provider’s scope? The New York chiropractor case turned on exactly this.
- Who is responsible for the results? Know who sees results, when a provider reviews them, and what happens with an urgent value.
- Which states are covered, and why are any excluded?
The Bottom Line
Who can order lab tests is decided by each state, and it comes down to licensed practitioners acting within their scope. If you’re a coach, trainer, gym owner, med spa owner or wellness brand without a clinical license, you can’t order labs for clients, and you shouldn’t interpret them. You can still sell lab testing under your own brand when a licensed provider orders each test.
