Yes. Many specialty laboratory tests can be collected at home, but it depends on the test and the type of specimen required. Urine, saliva, stool, cheek-swab, and some finger-prick samples can often be collected by the patient at home. Other tests require a traditional venous blood draw and may need to be completed by a phlebotomist or at a laboratory collection site.
At-home collection can make specialty laboratory testing more convenient, particularly when the testing requires multiple specimens, collection at a particular time of day, or samples such as stool or saliva that are easier to obtain at home.
However, collecting a sample at home does not necessarily mean that the laboratory test itself is performed at home. In many cases, you collect the specimen yourself, package it according to the laboratory's instructions, and send it to a clinical laboratory for analysis.
What Does “At-Home Specialty Lab Testing” Actually Mean?
There are two concepts that can easily be confused:
At-home specimen collection means you collect a blood spot, urine, saliva, stool, cheek swab, or another approved specimen at home and then send it to a laboratory for analysis.
At-home testing means both the sample collection and the actual test are performed at home, with the result generated without sending the specimen to a laboratory.
Many specialty laboratory panels fall into the first category.
The FDA similarly distinguishes tests involving home specimen collection from tests that are performed completely at home. Some direct-to-consumer tests, for example, involve collecting saliva or urine and sending the specimen to a laboratory rather than obtaining the result at home.
If you are new to this type of testing, our Complete Guide to Specialty Laboratory Testing explains how specialty tests differ from routine blood work and how physicians decide whether additional testing may be helpful.
What Types of Specialty Lab Samples Can Be Collected at Home?
The exact collection method depends on the laboratory and the individual test.
Common at-home specimen types may include:
Urine
Many specialty tests use urine samples.
Depending on the panel, urine testing may be used to evaluate selected environmental exposures, metabolic markers, hormones or hormone metabolites, organic acids, nutrients, or other compounds.
Some tests use a single urine sample, while others require several collections at specific times.
Patients should follow the instructions for the specific test being ordered, because requirements for first-morning urine, fasting, timing, refrigeration, medications, supplements, and shipping can differ considerably between tests.
For example, Vibrant Wellness provides patient collection protocols for several urine-based specialty tests, including specific instructions regarding sample volume and handling.
Saliva
Saliva is another specimen that can often be collected at home.
Depending on the test, saliva may be used for certain hormone, genetic, infectious, or other specialized measurements.
Some panels require only one saliva sample, while others require several samples collected throughout the day.
Because eating, drinking, brushing your teeth, medications, supplements, and the timing of collection may affect certain tests, it is important to follow the laboratory's instructions rather than assuming that every saliva test is collected the same way.
Stool
Stool-based specialty testing is generally designed to be collected at home.
A collection kit may include:
Collection material
Specimen tubes or containers
Labels
Protective packaging
Detailed instructions
Shipping materials
Depending on the panel, stool testing may evaluate gastrointestinal microorganisms, digestive markers, inflammatory markers, immune-related findings, or other characteristics of the gastrointestinal environment.
Vibrant Wellness, for example, provides patient-directed stool collection kits and instructions that allow specimens to be collected outside a laboratory and returned for analysis.
You can learn more about the broader role and limitations of these tests in our Specialty Laboratory Testing Resource Center.
Cheek or Buccal Swabs
Certain genetic and molecular tests can use cells collected from the inside of the cheek.
These collections are generally simple and may involve rubbing a sterile swab against the inside of the cheek for a specified period before placing it into the laboratory's collection container.
Patients should avoid assuming that a cheek swab can substitute for another specimen type. The laboratory determines which specimen is appropriate for the test being performed.
Finger-Prick or Dried Blood Spot Samples
Some specialty blood tests do not require a traditional venous blood draw.
Instead, a patient may use a small lancet to obtain blood from a fingertip and collect it into a small tube or onto specially designed collection material.
This is sometimes called dried blood spot, or DBS, testing.
Some Vibrant Wellness tests, for example, are specifically available using patient-collected dried blood spot samples.
However, dried blood spot testing is not interchangeable with venous blood for every laboratory test. Whether it can be used depends on the particular test methodology and the specimen type for which that test was developed.
Which Specialty Lab Tests Cannot Be Collected Completely at Home?
Some specialty tests require a conventional venous blood sample.
In these situations, blood is usually collected by a trained phlebotomist using a needle and collection tubes.
Depending on the testing arrangement, this may occur at:
A laboratory collection center
A physician's office
A mobile phlebotomy appointment
An in-home blood draw
Therefore, a test requiring venous blood does not always mean that you must travel to a laboratory.
For selected testing packages, Ask Dr. Hu's Specialty Laboratory Testing service can include standard in-home blood draw or specimen collection when required, subject to availability, the selected test, and service area.
Can an Entire Specialty Lab Test Be Completed Without Leaving Home?
In some cases, yes.
Certain specialty tests are designed so that the complete specimen-collection process can occur at home.
For example, depending on the specific panel, you may be able to:
Meet with your physician virtually.
Determine which laboratory test is appropriate.
Have a collection kit sent to you.
Collect urine, saliva, stool, cheek-swab, or eligible finger-prick specimens at home.
Package the specimen according to the laboratory instructions.
Return it using the provided shipping materials.
Have the laboratory analyze the specimen.
Review your results with your physician virtually.
Some specialty laboratories specifically categorize tests according to whether the entire sample collection can be completed from home. Vibrant Wellness, for example, identifies certain tests using dried blood spot, saliva, stool, urine, and other self-collected specimens as eligible for at-home collection.
Other tests may require a mobile phlebotomist to come to your home.
Is At-Home Sample Collection as Reliable as Laboratory Collection?
The location where a specimen is collected is only one part of laboratory quality.
What matters is whether the correct specimen is collected using the method required for that particular test and whether the sample is properly labeled, stored, transported, processed, and analyzed.
CMS regulates laboratories that perform clinical testing through the Clinical Laboratory Improvement Amendments, or CLIA. CMS specifically distinguishes facilities performing laboratory testing from locations that only collect or prepare specimens.
For a test designed and validated for patient self-collection, home collection may be an appropriate way to obtain the specimen.
However, errors during collection can potentially interfere with the sample.
What Can Go Wrong With an At-Home Sample?
Collection instructions matter.
Depending on the test, potential problems may include:
Collecting the wrong amount of specimen
Using the wrong collection tube
Collecting at the wrong time
Contaminating the specimen
Failing to follow fasting instructions when required
Taking medications or supplements contrary to test-specific instructions
Incorrectly labeling the specimen
Improper storage
Delaying shipment beyond the permitted interval
Exposure to inappropriate temperatures during handling
Incomplete collection of a timed specimen
A specimen that does not meet the laboratory's requirements may occasionally need to be recollected.
This is one reason that choosing the test should come before trying to determine how to collect it.
Do I Need to Stop Medications or Supplements Before Collecting a Sample?
Not unless your physician or the laboratory specifically instructs you to do so.
Preparation requirements can differ significantly between tests.
Some laboratory measurements can be affected by:
Food
Fasting
Hydration
Exercise
Alcohol
Caffeine
Medications
Vitamins and supplements
Menstrual timing
Time of day
Recent illness
Never stop a prescription medication solely because you are preparing for specialty laboratory testing unless the healthcare professional managing that medication advises you to do so.
Your physician should review any special preparation requirements before collection whenever they may influence the usefulness of the result.
Do At-Home Specialty Tests Need to Be Mailed Immediately?
It depends on the specimen.
Some specimens need prompt shipment, while others remain stable for a longer period under specified conditions.
The laboratory may instruct you to:
Ship the sample the same day
Refrigerate it temporarily
Freeze a particular specimen
Avoid collecting immediately before a weekend or holiday
Use an included cold pack
Place samples into designated protective packaging
Always use the instructions supplied with your specific collection kit rather than general laboratory advice found online.
Can Specialty Blood Tests Be Done at Home?
Sometimes.
There are generally three possibilities:
Finger-prick collection: Some specialty tests can use dried blood spot or small-volume capillary samples that patients collect themselves.
Mobile phlebotomy: A trained professional comes to your home and performs a conventional blood draw.
Laboratory collection: Certain tests require you to visit an appropriate phlebotomy or laboratory collection center.
The appropriate method depends on the laboratory, test methodology, amount of blood required, specimen stability, and other collection requirements.

Frequently Asked Questions
Can I collect a stool test at home?
Usually, yes, when the selected stool panel is specifically designed for patient collection. Follow the laboratory's instructions carefully regarding specimen quantity, collection containers, storage, and shipping.
Can I collect a urine test at home?
Many specialty urine tests are designed for home collection. The required timing varies. Some require a single specimen, while others may involve timed or multiple collections.
Can saliva testing be completed at home?
Many saliva-based tests can be collected at home. Follow the test-specific instructions regarding eating, drinking, oral hygiene, medications, supplements, and timing.
Can someone come to my house to draw my blood?
Depending on your location and the laboratory test being ordered, mobile phlebotomy or in-home blood collection may be available. Ask Dr. Hu currently offers in-home collection with qualifying specialty testing packages, subject to availability and service area.
Does every specialty lab test have an at-home option?
No. The specimen requirements depend on the specific laboratory test. Some require venous blood or another collection method that cannot be self-collected.
The Bottom Line
Many specialty laboratory tests can be collected at home.
Urine, saliva, stool, cheek-swab, and some finger-prick samples are particularly well suited to home collection. Other tests require a traditional blood draw, although mobile phlebotomy may sometimes allow that collection to occur in your home as well.
The most important consideration is not simply whether a test is convenient to complete.
A specialty laboratory test should be selected because it addresses a meaningful clinical question and because the result has the potential to influence your evaluation, treatment, or monitoring.
At Ask Dr. Hu, specialty testing is physician guided. We help determine whether testing is appropriate, select the laboratory panel, explain collection requirements, coordinate collection when necessary, and interpret the results in the context of your overall health.
