Order online for $499, walk into any of 2,000+ Labcorp locations for a blood draw — no doctor's visit needed. Screens 163 genes linked to inherited cancer, heart, and metabolic risk, with results in 10–21 days and a genetic counselor to help read them — but it is built for generally healthy adults, not for people with a strong family history.
The short version
$499, one walk-in visit, results in 10–21 days
The Marker genetic health panel ($499) analyzes 163 genes tied to more than 100 inherited conditions — hereditary cancers, heart disease, and metabolic disorders — from a single blood draw. Results arrive in 10 to 21 days, and a genetic counselor is included to help you understand them. The honest catch: this is a screen for generally healthy adults. If you already have a personal or strong family history of a genetic condition, this is the wrong test — you need clinical genetic testing through a doctor, not a consumer panel.

What 163 genes actually covers — and what it does not
The panel tests for variants in 163 genes, grouped into three buckets. Hereditary cancers: BRCA1 and BRCA2 (breast, ovarian, prostate, and other cancers), the Lynch syndrome genes MLH1, MSH2, MSH6, and PMS2 (colorectal and other cancers), TP53, and APC, among others. Heart disease: genes tied to cardiomyopathies and arrhythmias, plus the familial hypercholesterolemia genes LDLR, APOB, and PCSK9. Metabolic and other inherited conditions: HFE (hereditary hemochromatosis), GLA (Fabry disease), ATP7B (Wilson disease), and SERPINA1 (alpha-1 antitrypsin deficiency), among others. What it does not do: it is not whole-genome sequencing — it reads the listed genes, not your entire DNA — and it does not diagnose disease. A variant found here is a risk flag, not a diagnosis, and a clean result does not rule out risk: most cancers and heart disease are not inherited in a single gene, and the panel cannot see what it does not test for.
Who this panel is for — and who should not buy it
This panel is intended for generally healthy adults who want a picture of their inherited risk — people with no personal history and no strong family history of a genetic condition, who would act on what they learn. It is not appropriate for high-risk individuals: if you have a personal history of cancer or heart disease at a young age, or a strong family history of a genetic condition, this consumer panel is the wrong tool. Clinical genetic testing — ordered through a doctor, with pre-test counseling and a test chosen for your family's specific history — is the right route, and it is often covered by insurance where a consumer panel is not. The test must be taken by the purchaser, and it is available to adults 18 to 100. If you are buying it because a relative just tested positive for a variant, ask your doctor about targeted testing for that variant first — it is cheaper and more informative than a 163-gene sweep.
What a result means — positive, negative, and in between
A positive result means the lab found a variant in one of the 163 genes that is associated with higher risk for a condition. It does not mean you have the condition, or will develop it: many carriers never do, and risk varies by gene, variant, and family history. What it does mean is a conversation — with the included genetic counselor first, then with your clinician — about screening, prevention, and whether blood relatives should be told, since they may share the variant. A negative result means no variant was found in the genes tested. That lowers the inherited-risk picture but does not erase it: the panel covers 163 genes, not every gene, and most disease risk comes from a mix of many small genetic effects plus lifestyle and environment that no panel measures. A third outcome is possible too: a variant of uncertain significance, where the lab finds a change it cannot yet classify as harmful or harmless. That result is a waiting game, not an answer — and it is one more reason the counselor is part of the package, not an add-on.
A cholesterol number changes with diet; a gene variant does not. Think before you test about whether you want this knowledge, who else in your family it affects, and what you would do differently with a positive result. If the answer is nothing, the test buys worry, not health.
Before you order: privacy, insurance, and the law
Genetic information is treated differently from other lab results, and the law is only partial protection. The federal Genetic Information Nondiscrimination Act (GINA, 2008) bars health insurers and employers from using genetic information against you — a health plan cannot raise your premium or deny coverage because of a variant, and an employer cannot use it in hiring or firing. But GINA does not cover life insurance, disability insurance, or long-term-care insurance, where genetic results can still be requested and used. Your results live in your secure portal, and the test is self-pay, so no insurer sees a claim for it — but the result itself is yours to disclose or not, and once shared with a clinician it becomes part of your medical record. The practical rule: decide before ordering whether you are comfortable with a result that follows you, not just with the price.
How walk-in genetic testing works
You order the test online, then visit a patient service center for a standard venous blood draw — no doctor’s order, no appointment, and no insurance needed. The wait is the long part: results typically post to a secure portal 10 to 21 days after your sample arrives at the lab, because sequencing and analysis take longer than a blood-chemistry test. HSA/FSA accepted. When the results land, access to a genetic counselor is included — use it before you act on anything, especially a positive result. The counselor helps you understand what the variant means, what it does not mean, and what next steps look like — then take the result to your own clinician for any screening or prevention decisions.
Common questions
Does this test diagnose cancer or heart disease?
No. It screens for inherited risk variants in 163 genes. A positive result means higher risk, not a diagnosis — many carriers never develop the condition — and a negative result does not rule out risk. Diagnosis and any screening plan need a clinician.
Is this a saliva kit or a blood draw?
A blood draw, in person. You order online, then visit a patient service center for the sample collection — no appointment needed.
How long do results take?
Typically 10 to 21 days from when your sample arrives at the lab — longer than a standard blood test, because sequencing and analysis take time. Results post to a secure online portal.
Is genetic counseling really included?
Yes. Access to a genetic counselor is included to help you understand your results and next steps — use it before acting on a positive result, and before telling relatives.
I have a strong family history of breast cancer — is this the right test?
No. The panel is intended for generally healthy adults, not high-risk individuals. With a personal or strong family history of a genetic condition, talk to your doctor about clinical genetic testing chosen for your family’s history — it is often covered by insurance and comes with pre-test counseling.
Can a health insurer use my results against me?
No — the federal Genetic Information Nondiscrimination Act (GINA) bars health insurers and employers from using genetic information against you. But GINA does not cover life, disability, or long-term-care insurance, where genetic results can still be requested and used.
