What Does Race Actually Mean In Healthcare?

Race is a social category, not a biological one. In healthcare, that distinction matters more than most people realize. Doctors and researchers have used race for decades to guide medical decisions, but the science behind those decisions is often shaky. Race does not change your blood, your cells, or your organs. It does shape your environment, your stress levels, and your access to care — and those factors genuinely affect your health.

Why Is Race Not a Biological Fact?

Human genetic variation does not sort neatly into racial groups. Studies consistently show that there is more genetic variation within any single racial group than between different racial groups. If you picked two Black Americans at random, their genetic differences would likely be greater than the average difference between a Black American and a white American.

Racial categories were created by societies, not by nature. They have changed over time and differ between countries. A person classified as “Black” in the United States might be classified differently in Brazil or South Africa. Biology does not work that way. Your DNA does not change based on which country you live in.

What race does capture is shared ancestry in a rough sense. Some genetic variants are more common in certain ancestral populations. But ancestry is not the same as race. Ancestry is a genetic fact. Race is a social label that imperfectly tracks ancestry.

How Did Race Get Into Medicine in the First Place?

Race entered medicine through historical error and bias, not through careful science. In the 19th century, doctors used race to justify slavery and colonial practices. They claimed biological differences explained why Black people could endure harsh conditions or why certain diseases only affected certain groups. Those claims were false.

Some of those false beliefs persist in medical textbooks and clinical tools. For example, some kidney function calculators include race as a variable. The original data used to create those calculators came from small studies with flawed assumptions. Recent research has shown that removing race from these calculations produces more accurate results for Black patients.

Lung function tests offer another example. Some spirometers — devices that measure breathing — have a “race correction” button. Pressing it adjusts the results downward for Black patients. This can make lung damage look less severe than it actually is. Some studies suggest this leads to underdiagnosis of lung disease in Black patients.

What Does Race Actually Mean in Healthcare Today?

In current clinical practice, race is used as a proxy for things that are hard to measure directly. Those things include environmental exposures, discrimination, stress, diet patterns, and access to care. Race is not the cause of health differences. It is a stand-in for the real causes.

Consider high blood pressure. Black Americans have higher rates of hypertension than white Americans. This is not because Black bodies are biologically prone to high blood pressure. Research points to chronic stress from discrimination, neighborhoods with fewer healthy food options, and less access to quality medical care. These are social conditions, not genetic ones.

When a doctor sees a Black patient and thinks about hypertension risk, the doctor is responding to real statistical patterns. But acting on race alone can lead to wrong decisions for individual patients. A Black patient with normal blood pressure does not need hypertension treatment just because of race. A white patient with high blood pressure needs treatment regardless of race.

When Does Race Matter for Medical Decisions?

There are a few situations where race-based adjustments are still common in medicine. These are increasingly controversial, and the evidence is mixed.

Kidney function is the most discussed example. The eGFR blood test estimates how well your kidneys filter waste. Many labs historically adjusted this number upward for Black patients. The logic was that Black people have higher average muscle mass, which affects creatinine levels. But the data behind this adjustment came from limited studies. Major medical organizations now recommend against using race in eGFR calculations.

Heart failure treatment also has a race-based history. A medication called BiDil was approved specifically for Black patients with heart failure. The approval was based on a trial that only enrolled Black participants. The drug works, but researchers later found that the benefit was not unique to Black patients. The drug was simply understudied in other groups.

Some genetic tests for ancestry can identify increased risk for certain conditions. For example, BRCA mutations are more common in people of Ashkenazi Jewish descent. But this is ancestry, not race. And even here, family history matters more than ancestry alone.

Why Do Health Outcomes Differ Between Racial Groups?

Health disparities between racial groups in the United States are large and well documented. Black infants die at roughly twice the rate of white infants. Black women have higher rates of maternal mortality. Hispanic and Black adults have higher rates of diabetes. These differences are real.

The causes are social, not genetic. Housing segregation concentrates poverty in certain neighborhoods. Poor neighborhoods have fewer grocery stores, more pollution, and less safe spaces for exercise. These conditions drive higher rates of obesity, diabetes, and heart disease.

Discrimination in healthcare also plays a role. Studies have found that Black patients receive less pain medication than white patients with the same injuries. Some research suggests that false beliefs about biological differences — such as the idea that Black people have thicker skin or feel less pain — influence treatment decisions.

Stress from discrimination damages health directly. Chronic stress raises cortisol levels, which can increase blood pressure and blood sugar. Over years, this wear and tear on the body contributes to the very conditions that doctors often blame on race.

What Is the Alternative to Race-Based Medicine?

The shift in medicine is toward using actual measured data instead of race as a guess. This means measuring blood pressure, cholesterol, blood sugar, and kidney function directly. It means asking about family history, diet, exercise, and stress. It means considering where a person lives and works.

Some researchers are working on polygenic risk scores — calculations that look at many genetic variants at once. These scores can estimate disease risk more precisely than race. But they are not ready for widespread clinical use. They also raise concerns about privacy and equity.

For now, the best approach is what doctors call individualized medicine. Treat the person in front of you based on their actual test results and symptoms. Do not assume a patient’s risk based on skin color or ethnicity.

This does not mean ignoring race entirely. Race still matters because it correlates with real experiences of discrimination and unequal treatment. But those experiences are the problem to address — not the patient’s body.

What Should Patients Do With This Information?

If you are a patient, you can advocate for yourself by asking questions. Ask your doctor what your actual test results show. Ask whether race was used in any calculation that affects your care. You have the right to understand how clinical decisions are made.

If a doctor tells you that a condition is more common in your racial group, ask what that means for you personally. The statistical pattern may not apply to your situation. Your individual risk depends on your family history, your environment, and your measured health markers.

You can also share your social context with your doctor. Mention if you are experiencing discrimination, financial stress, or difficulty accessing healthy food. These factors are medical information. They affect your health as much as your cholesterol level.

What Does the Future of Race in Medicine Look Like?

Medical schools are changing how they teach race. Many now teach that race is a social construct with limited biological meaning. Textbooks are being revised. Clinical calculators are being updated to remove race adjustments.

This change is not complete. Many older clinicians were trained with race-based thinking. Some clinical tools still include race. The transition will take time.

Research is also shifting toward studying the effects of racism rather than race. This means measuring discrimination, segregation, and unequal treatment directly. It means asking how being treated differently affects health over a lifetime. This research direction is more accurate and more useful for improving health outcomes.

The honest summary is this: race predicts health outcomes in the United States because it predicts exposure to unequal conditions. Race itself does not cause disease. When you separate the social effects of racism from the biology of the human body, you get a clearer picture of what actually drives health and illness.
