BRCA gene testing is available through several channels: your doctor’s office, cancer centers, genetic counseling clinics, and even at-home test kits. The right option depends on your family history, insurance situation, and how comprehensive you need the results to be. Most people start by talking to their primary care doctor or OB-GYN, who can order the test directly or refer you to a genetic counselor.
Hospitals and Cancer Centers
The most thorough BRCA testing happens through clinical laboratories connected to hospitals, cancer centers, and specialized genetics clinics. Major academic medical centers often have dedicated hereditary cancer clinics. UCSF, for example, runs a Hereditary Cancer Clinic that integrates genetic testing with ongoing cancer risk management. Many NCI-designated comprehensive cancer centers across the country offer similar programs.
You don’t necessarily need a major cancer center, though. Community hospitals, OB-GYN offices, and primary care practices can all order clinical BRCA testing. The test itself uses a blood draw, saliva sample, or cheek swab, and results typically come back within a few weeks. What matters most is that the lab performing the analysis is clinically certified and screens for the full range of known variants, not just a handful.
Genetic Counselors: The Recommended First Step
Before testing, most guidelines recommend meeting with a genetic counselor. These professionals assess your personal and family history to determine whether testing makes sense, explain what results could mean, and help you decide on next steps regardless of the outcome. Many insurance plans and Medicare require documented genetic counseling before they’ll cover the test.
You can find a genetic counselor through your doctor’s referral, through a hospital genetics department, or by searching the National Society of Genetic Counselors directory online. Some counselors now offer telehealth appointments, which makes access easier if you don’t live near a major medical center.
At-Home Test Kits: What They Miss
Companies like 23andMe offer direct-to-consumer genetic tests that screen for BRCA variants. These kits are convenient: you spit into a tube at home and mail it back. But they check for only three specific BRCA mutations, all of which are most common in people of Ashkenazi Jewish descent. There are more than 1,000 known harmful BRCA variants.
The gap is significant. Research covered by the National Library of Medicine found that 23andMe misses nearly 90 percent of people carrying risky BRCA mutations. On top of that, third-party analysis of raw DNA data from consumer kits has produced false positives, meaning people were told they had a variant they didn’t actually carry. A negative result on a consumer test does not mean you’re in the clear, and a positive result needs confirmation in a clinical lab. These kits can be a starting point if you’re curious, but they are not a substitute for clinical-grade testing.
Who Should Get Tested
BRCA testing isn’t recommended as routine screening for everyone. National Comprehensive Cancer Network guidelines focus testing on people whose personal or family history suggests a hereditary pattern. That generally includes people with a close relative (parent, sibling, child) diagnosed with breast cancer before age 50, a family member with ovarian cancer at any age, multiple breast cancers on the same side of the family, a male relative with breast cancer, or a known BRCA mutation already identified in the family. Ashkenazi Jewish ancestry also raises the baseline likelihood enough to warrant discussion with a provider.
Men should know this applies to them too. Men who carry harmful BRCA2 changes face a 19 to 61 percent chance of developing prostate cancer by age 80 and up to a 7 percent chance of male breast cancer by age 70. BRCA mutations in both genes also raise pancreatic cancer risk to between 5 and 10 percent over a lifetime. Men with a strong family history of these cancers have good reason to pursue testing and, if positive, to discuss screening options with their doctor.
Cost and Insurance Coverage
Under the Affordable Care Act, insurance plans must cover genetic counseling for women at higher risk of breast cancer, and many plans also cover the testing itself when a doctor recommends it. That can mean zero out-of-pocket cost. The key is getting a referral and having documented medical necessity, which is where genetic counseling comes in.
Medicare covers BRCA testing when specific criteria are met: you need a personal or family history that fits established risk guidelines, genetic counseling from a qualified professional before and after testing, and documentation of medical necessity in your record. For multi-gene panels, Medicare requires that every gene on the panel be relevant to your specific history.
If you’re uninsured or underinsured, financial assistance programs exist. Quest Diagnostics caps out-of-pocket costs at $200 for qualified patients and offers testing at no cost for people whose income falls at or below the federal poverty level. Payment plans are also available. Other major testing laboratories run similar assistance programs, so it’s worth asking before assuming you can’t afford it.
Privacy Protections for Your Results
A common concern is whether genetic test results could be used against you. The Genetic Information Nondiscrimination Act (GINA) makes it illegal for employers to use genetic information in hiring, firing, promotions, pay, or any other employment decision. Employers cannot request, require, or purchase your genetic information. The law also prohibits health insurers from using genetic test results to deny coverage or raise premiums.
GINA has a notable gap, though. It does not cover life insurance, disability insurance, or long-term care insurance. Companies in those industries can legally ask about genetic test results and factor them into decisions. Some people choose to secure these policies before undergoing BRCA testing for this reason.
What to Expect From the Test Itself
The physical part of BRCA testing is simple. A blood draw takes less than five minutes. If your provider uses saliva or cheek swab collection, you may even be able to do it yourself in the office. Results from a clinical lab typically take two to four weeks.
Results fall into three categories: positive (a harmful variant was found), negative (no harmful variant detected), or a variant of uncertain significance, meaning a change was found but scientists don’t yet know whether it increases cancer risk. A genetic counselor can walk you through what your specific result means for your screening schedule, risk-reduction options, and whether family members should consider testing. If you test positive, your close blood relatives each have a 50 percent chance of carrying the same variant.
