A routine checkup is a preventive medical visit where your doctor assesses your overall health, screens for common diseases, updates vaccinations, and identifies risk factors before symptoms appear. Most healthy adults schedule one annually, though the specific tests and screenings you receive depend heavily on your age, sex, and personal risk factors.
What Happens During the Visit
A routine checkup typically starts with a nurse or medical assistant recording your vital signs. The two most important numbers are your blood pressure and resting heart rate. Normal blood pressure falls between 90/60 and 120/80 mmHg, and a healthy resting pulse ranges from 60 to 100 beats per minute. You’ll also be weighed and measured so your provider can calculate your BMI.
After vitals, your doctor performs a physical examination using four basic techniques: listening to your heart and lungs with a stethoscope, visually inspecting your body, feeling specific areas with their hands, and tapping on parts of your body to assess what’s underneath. During the hands-on portion, your provider will gently press along the sides of your neck to check your lymph nodes for swelling, and feel your abdomen to evaluate the size and position of your organs. You may be asked to lie down for this part. They’ll also look in your ears, eyes, nose, and throat, and may check your reflexes.
The whole exam portion usually takes 15 to 20 minutes, but the full appointment often runs 30 to 45 minutes once you factor in the conversation about your health history, lifestyle, and any concerns you want to raise.
Blood Tests You Can Expect
Your doctor may order bloodwork either before or during your visit. Three panels show up most often in routine care:
- Complete blood count (CBC): One of the most common blood tests in medicine. It measures your red blood cells, white blood cells, and platelets, giving your doctor a broad snapshot of your overall health and ability to fight infection.
- Basic metabolic panel (BMP): This checks blood sugar, calcium, electrolytes, and kidney function. It’s a quick way to flag metabolic problems that haven’t caused symptoms yet.
- Lipid panel: This measures your total cholesterol, LDL (“bad”) cholesterol, HDL (“good”) cholesterol, and triglycerides. The results help your doctor estimate your risk of heart disease and decide whether lifestyle changes or medication are warranted.
Not every checkup requires bloodwork. Your doctor decides based on your age, existing conditions, and how recently you were last tested. If you’re young and healthy with no risk factors, you might go several years between blood draws.
Age-Based Screenings
The most important function of a routine checkup is connecting you with screenings appropriate for your age and risk profile. The U.S. Preventive Services Task Force maintains a list of recommended screenings, and your doctor uses these guidelines to decide what you need.
Blood pressure screening is recommended for all adults 18 and older. Diabetes screening begins at age 35 for adults who are overweight or obese. Colorectal cancer screening starts at 45 for everyone, regardless of family history, and continues through age 75. Women should begin mammograms at 40, repeated every two years through age 74. Cervical cancer screening starts at 21, with a Pap test every three years for women in their twenties. After 30, women can switch to testing every five years with an HPV test alone or combined with a Pap.
Lung cancer screening applies to a narrower group: adults aged 50 to 80 with a 20 pack-year smoking history who currently smoke or quit within the last 15 years. Men aged 65 to 75 who have ever smoked are recommended a one-time ultrasound to check for abdominal aortic aneurysm.
Your doctor may also assess your 10-year cardiovascular risk using factors like cholesterol, blood pressure, diabetes status, and smoking history. If that risk hits 10% or higher and you’re between 40 and 75, preventive medication may be part of the conversation.
Vaccinations
A checkup is a natural time to catch up on vaccines. The CDC’s adult immunization schedule includes several that apply to most people: an annual flu shot, a tetanus and pertussis booster every 10 years, and updated COVID-19 vaccines. HPV vaccination is routinely recommended through age 26, with the option to discuss it with your doctor up to age 45. Hepatitis A and B vaccines are recommended for adults who haven’t been vaccinated, and pneumococcal vaccines become relevant as you get older or if you have certain health conditions.
Mental Health Screening
Many primary care offices now screen for depression and anxiety as part of a routine visit. You may be handed a short questionnaire in the waiting room or on a tablet before your appointment. The two most widely used tools are the PHQ-9 for depression and the GAD-7 for anxiety. The PHQ-9 asks nine questions about symptoms like low energy, trouble sleeping, and loss of interest in activities. The GAD-7 covers seven questions about worry, restlessness, and irritability. Both use a simple scoring system where higher numbers indicate more severe symptoms. These aren’t diagnostic on their own, but they give your doctor a structured way to open a conversation about your mental health.
How to Prepare
A little preparation makes the visit more productive. Bring an updated list of every medication you take, including over-the-counter supplements and doses. If you have a family history of heart disease, cancer, diabetes, or other major conditions, write that down too. Your doctor uses family history to decide which screenings to recommend and when to start them.
Think about what you want to discuss before you arrive. If you’ve noticed changes in your sleep, mood, energy, digestion, or pain levels, mention them even if they seem minor. Routine checkups are also a good time to ask about lifestyle factors like exercise, diet, alcohol use, and stress. Many people leave appointments wishing they’d asked about something they forgot in the moment, so a written list helps.
Insurance Coverage
Most health insurance plans cover one preventive visit per year at no cost to you, with no copay or deductible. This is true for plans under the Affordable Care Act and for Medicare, which covers a yearly “Wellness” visit with no out-of-pocket cost as long as your provider accepts Medicare assignment.
There’s an important distinction, though. A preventive wellness visit covers the checkup itself, recommended screenings, and health counseling. If your doctor discovers a problem during that visit and orders additional tests or addresses a new concern, those extras may be billed separately and could trigger a copay or deductible. For example, Medicare’s yearly wellness visit is not the same as a full physical exam, and a physical may not be covered. If you’re unsure what your plan includes, call your insurer before scheduling.
Do Routine Checkups Actually Help?
This is worth addressing honestly. A large Cochrane review pooling data from 11 trials and over 233,000 participants found that general health checks had no measurable effect on overall mortality, cancer mortality, or heart disease events over follow-up periods of 4 to 30 years. The evidence was rated high-certainty for most of these outcomes.
That sounds discouraging, but context matters. The review looked at blanket “health checks” applied to broad populations, not targeted screening based on individual risk. The value of a routine checkup lies less in the physical exam itself and more in the specific, evidence-based screenings it connects you to: catching high blood pressure before a stroke, identifying prediabetes before it progresses, or detecting colorectal cancer at a treatable stage. Health checks also appear to increase the number of new diagnoses, meaning conditions are found earlier even if the overall mortality numbers don’t shift in large population studies.
The practical benefit of a routine checkup is that it gives you a relationship with a primary care provider who knows your history, keeps your screenings on schedule, and can spot changes over time that a single visit wouldn’t catch.
