Is genetic testing covered by insurance?

Genetic testing is sometimes covered by insurance when there is a strong family history or specific clinical indication, like a first-degree relative with BRCA-related cancer. Most optimization or preventive genomic panels are out-of-pocket. We help you find the most cost-effective option.

Is genetic testing private?

Yes, the genetic testing we use prioritizes privacy. We work with labs that comply with HIPAA (the federal health privacy law) and GINA (the Genetic Information Nondiscrimination Act, which prevents discrimination by employers and most health insurers). We do not share your data with third parties without your written consent.

Can the test be done at home?

Yes, the test can be done at home. Most of the advanced tests we use are simple saliva or cheek swab kits that ship directly to your home in Philadelphia. We then review the results together by [virtual consultation](/about/texting-your-doctor).

Should I get tested if I have a family history of cancer?

You should consider genetic testing if you have a strong family history of cancer, especially breast, ovarian, prostate, pancreatic, or colon cancer. We use a focused intake to decide if testing is appropriate and which panel to use, often guided by NCCN (National Comprehensive Cancer Network) criteria.

Can I use my 23andMe data?

Yes, you can use your 23andMe or Ancestry raw data for some clinical context, although DTC tests have important limits. We can interpret raw data through services that focus on clinically validated variants. For high-stakes decisions (like BRCA), a confirmatory clinical test is required.

Is genetic testing painful?

Genetic testing is not painful. Most tests use a saliva sample or cheek swab. Some advanced panels require a blood draw, which is the same as a routine lab test.

How long do genetic results take?

Genetic results usually take 2 to 4 weeks, depending on the lab and the size of the panel. We schedule a follow-up visit to walk through the report once it arrives.

What if my genetic test shows something concerning?

If your genetic test shows something concerning, we sit down and explain exactly what it means, how it changes your screening or treatment, and what your options are. For complex findings, we coordinate with genetic counselors and specialists.

What is APOE and why does it matter?

APOE (apolipoprotein E) is a gene that influences cholesterol metabolism and dementia risk. Carriers of one or two APOE4 alleles have higher long-term risk of Alzheimer's disease and cardiovascular disease. We use the result to plan earlier and more thorough cardiovascular and brain-health prevention.

What does MTHFR actually do?

MTHFR (methylenetetrahydrofolate reductase) is a gene that codes for an enzyme involved in folate metabolism and homocysteine processing. Common MTHFR variants slightly affect how the body handles folate and B12. The clinical importance is often overhyped; we use it as one input among many, not a master switch.

How does pharmacogenomics change prescribing?

Pharmacogenomics changes prescribing by predicting how you metabolize specific drugs (like SSRIs, blood thinners, statins, or pain medications). Knowing if you are a fast or slow metabolizer helps us pick the right starting dose, avoid toxicity, and reduce trial-and-error switching.

When is BRCA testing appropriate?

BRCA testing is appropriate when there is personal or family history of breast, ovarian, pancreatic, or aggressive prostate cancer, especially at younger ages. Ashkenazi Jewish ancestry also raises the threshold for testing because of higher founder mutation frequency.

What is polygenic risk scoring?

Polygenic risk scoring (PRS) combines small effects from many genetic variants into a single risk number for a disease, such as coronary artery disease or type 2 diabetes. PRS tools are improving but still imperfect. We use them as one part of a multi-factor risk assessment.

How does genetic testing affect cancer screening intervals?

Genetic testing can change cancer screening intervals. For example, BRCA1 carriers often start annual breast MRI in their 20s and consider risk-reducing surgery later. APC variants raise colon cancer risk and trigger earlier colonoscopies. Each finding tailors the schedule.

Are direct-to-consumer hereditary cancer tests reliable?

Direct-to-consumer hereditary cancer tests catch only a small subset of variants and miss many clinically important mutations. A negative DTC test does not rule out hereditary cancer risk. For clinical decisions, we use a comprehensive panel from a medical-grade lab.

How do you balance genetic anxiety with useful information?

We balance genetic anxiety with useful information by framing results as guidance, not fate. Most variants raise risk modestly, and lifestyle changes can offset much of that risk. We focus on what the result tells us to *do*, not just what it says to fear.

Can children be tested?

Children can be tested for specific conditions when there is a clear medical reason (for example, family history of an early-onset cancer or a treatable condition). We avoid speculative testing for adult-onset conditions in childhood, since the result is not actionable yet and can cause unnecessary worry.

What is the role of epigenetics?

Epigenetics is the study of how environment and behavior influence gene activity without changing the DNA sequence itself. Diet, stress, sleep, and toxin exposure all affect epigenetic patterns. This is why lifestyle changes can shift outcomes even when genes stay the same.

How does Fishtown Medicine handle uncertain or "VUS" findings?

We handle uncertain or "VUS" findings (variants of uncertain significance) by interpreting them with humility. A VUS is a genetic change with unclear clinical meaning. We track the variant in databases that update over time and avoid making major decisions until the evidence is clearer.

Will genetic data affect my insurance?

Genetic data is protected from health insurer discrimination by GINA in most cases. GINA does not cover life insurance, disability insurance, or long-term care insurance. We discuss those nuances before any genetic test so you can make an informed choice.

TL;DR · 30-second take

Genetic testing in our practice means clinically validated panels that change daily care: cardiovascular markers like Lp(a) and APOE, methylation genes (MTHFR), pharmacogenomics for safer prescribing, and BRCA1/2 when family history calls for it. We use data to turn risk into a prevention plan.

Precision Prevention: The Role of Genetic Testing

TL;DR: At Fishtown Medicine, your genes are not your destiny. They are your roadmap. By using genetic testing, we can identify your unique predispositions and create a personalized health strategy that offsets your risks before they become problems. The goal is "actionable genomics," meaning information we can use this week, not interesting trivia. Below we explain how we use genetic data, which markers matter most, and how we keep this affordable and focused on healthspan.

How is clinical genetic testing different from direct-to-consumer DNA tests?

Clinical genetic testing is different from direct-to-consumer (DTC) DNA tests because it uses higher-resolution sequencing, lab-validated reporting, and clinical interpretation. Many people in Philadelphia have tried services like 23andMe or Ancestry. Those tests are great for genealogy, but they often lack the clinical depth required for serious medical decision-making. We look for actionable genomics, the variants that actually change how we treat you today. We do not just tell you that you have a higher risk for something. We use that information to adjust your nutrition, your movement, and your screening intervals.

How do we use genetic data in clinical care?

We use genetic data in three specific ways: risk stratification, nutrigenomics, and pharmacogenomics. Each connects directly to a decision about your daily care.

1. Risk Stratification

If you have a genetic predisposition for early-onset cardiovascular disease (for example, elevated Lp(a)), we do not wait until your 50s to start monitoring your arteries. We start in your 30s.

2. Nutrigenomics

Your genes influence how you process fats, carbohydrates, and specific micronutrients. By understanding your nutrigenomic profile, we can recommend a diet that is built for your unique metabolism. Nutrigenomics is the study of how genes and nutrition interact.

3. Pharmacogenomics

We use genetic data to understand how you metabolize medications. This lets us choose the right medication and dose from the start, which avoids the trial-and-error process common in traditional medicine. Pharmacogenomics is the science of how genes affect drug response.

Which key genetic markers do we analyze?

We analyze the genetic markers with the highest impact on longevity and daily clinical decisions. While we can review thousands of variants, we focus on a small set with the strongest evidence.

Lp(a) and APOE: Important for cardiovascular and neurodegenerative risk.
MTHFR and Methylation Pathways: Influence how your body handles inflammation and B-vitamins.
Cancer Predisposition Panels: Screen for variants like BRCA1 and BRCA2 when clinically indicated.
Detoxification Genes: Help us understand how your liver processes environmental compounds.

Guidelines from the Clinic

"I often tell my patients: genes load the gun, but lifestyle pulls the trigger. Knowing which gaps are in your genetic armor lets us spend our energy in the right places. If we know you are genetically predisposed to poor insulin sensitivity, we double down on your [Zone 2 training](/longevity/muscle-vo2max). We are using data to turn probabilities into prevention."

How Fishtown Medicine Approaches Genomics

We are clinical-first. We do not order every test on every patient. Instead, we use your medical history and your goals to decide which genetic tests will give the most value. We then spend the time to walk you through the results, so you understand exactly what the data means for your daily life.

Actionable Steps in Philly

Start leveraging your genetic data.

Gather Family History: Talk to your relatives about any patterns of early-onset disease. This is the first genetic test.
Review Old Results: If you have done a 23andMe or Ancestry test, we can often help you re-interpret that raw data through a clinical lens.
Consult Before You Test: Do not spend money on generic DNA kits. Let's discuss which high-resolution tests are actually relevant to your healthspan goals.
Know the Costs: Some panels are insurance-covered with strong family history; others are cash-pay. We map this out before testing.
