Direct-to-Consumer Lab Testing: Where to Order Your Own Laboratory Tests

Have you ever wanted to check your vitamin D level, thyroid function, hormones, or other health markers without scheduling a separate doctor’s appointment?

Today, many companies offer direct-to-consumer (DTC) laboratory testing, allowing individuals to select and purchase tests online or at participating walk-in locations.

Some companies operate their own laboratories, while others arrange testing through established laboratories such as Quest Diagnostics or Labcorp.

This guide provides a convenient directory of companies, the general types of laboratory tests they offer, and where to find them.

Direct-to-Consumer Lab Testing Companies

The following companies offer consumer-accessible testing services. Test availability varies by location, and some services arrange the required laboratory order through an affiliated licensed healthcare professional.

Specialty Functional Medicine Laboratories

Some specialized tests are typically ordered through a healthcare professional rather than purchased directly from the laboratory by an individual consumer.

These laboratories may offer testing beyond standard bloodwork.

Some specialty tests may also be available through third-party ordering services. Check with the individual laboratory or ordering provider for current access requirements.

What Kinds of Lab Tests Can You Order?

Here are some common testing categories to help you find what you’re looking for.

Not every company offers every test. Use the company’s online directory to confirm the exact test and collection method.

How Does Direct-to-Consumer Testing Work?

Although procedures vary by company, the process is usually straightforward.

Step 1: Select your test. Visit the company’s website, browse its testing categories, and choose the laboratory test or panel you want.

Step 2: Purchase your test. Most services accept online payment. Some also accept eligible HSA or FSA funds.

Step 3: Complete the sample collection. Depending on the test, you may visit a participating laboratory, use a walk-in collection center, arrange an in-home blood draw, or collect a sample using a mailed kit.

Step 4: Receive your results. Results are generally delivered through a secure online account or patient portal.

Step 5: Share your results. You can save your reports and share them with a qualified healthcare professional for interpretation and follow-up.

Frequently Asked Questions

Do I need a doctor’s order?

Many direct-to-consumer services allow you to purchase testing without visiting your own doctor first. Some arrange for a licensed healthcare professional to authorize the laboratory order.

Specific requirements depend on the test, provider, and state.

Can I use insurance?

Most consumer-ordering services require payment at the time of purchase and do not submit claims to health insurance. Some payments may qualify for reimbursement through HSA or FSA accounts, depending on your plan.

Can I order specialty tests such as GI-MAP, DUTCH, or organic acids?

Some specialty tests are available only through approved healthcare professionals or authorized ordering services. Consult the laboratory’s website for current requirements.

Are these services available in every state?

Not always. Testing availability can differ by state, company, test type, and patient age.

For example, Quest Health’s consumer ordering service does not currently offer testing in Arizona, Hawaii, or Puerto Rico. Arizona residents can explore Sonora Quest’s My Lab ReQuest program.

Can I compare prices between companies?

Yes. Several online services offer overlapping test menus, making it possible to compare the cost of an individual test or a combination of tests.

Remember to compare the complete price, including any ordering, specimen-collection, and service fees.

Choosing a Laboratory Service

The right service depends on which tests you need, whether you prefer home or in-person collection, and which companies are available where you live.

You may find that one company offers convenient routine bloodwork while another provides a particular specialty test.

Save copies of your reports so that your healthcare professionals can review results and compare measurements over time.
