A general checkup typically takes about 30 minutes and covers a combination of vital signs, a physical exam, blood work, and age-appropriate screenings. The exact components depend on your age, sex, and personal risk factors, but the core structure is similar for most adults.
Vital Signs and Physical Exam
Every checkup starts with a set of baseline measurements. A nurse or medical assistant will record your blood pressure, heart rate, temperature, respiratory rate, and weight. These numbers give your provider a snapshot of your overall health and flag anything that needs a closer look.
During the physical exam itself, your provider will listen to your heart and lungs with a stethoscope, feel your abdomen for tenderness or organ enlargement, check your ears, nose, and throat, and look at your skin for any unusual moles or changes. They’ll also feel along your neck to check your thyroid and lymph nodes. If you have a known condition like high blood pressure or diabetes, expect your provider to spend extra time on the systems those conditions affect.
Standard Blood Work
Most providers order blood tests as part of a routine checkup. The most common panels include a complete blood count, which measures your red and white blood cells and can reveal anemia, infection, or clotting issues, and a comprehensive metabolic panel, which checks your blood sugar, kidney function, liver function, and electrolyte levels. A cholesterol panel is also standard, measuring your total cholesterol, LDL, HDL, and triglycerides to assess heart disease risk.
If your provider orders a cholesterol panel or a fasting blood sugar test, you’ll need to avoid eating or drinking anything except plain water for 8 to 12 hours beforehand. Skip gum, smoking, and exercise during that fasting window as well. Keep taking your prescription medications unless your provider specifically tells you to stop, and let them know about any vitamins or supplements you use. Bringing a snack to eat right after the blood draw is a good idea, since fasting can leave you feeling lightheaded.
Mental Health Screening
Many primary care offices now include a brief mental health check as part of the standard visit. You may be handed a short questionnaire in the waiting room or on a tablet before you see your provider. These typically ask about your mood, energy level, sleep, appetite, and feelings of worry or hopelessness over the past two weeks. The most widely used tools are the PHQ-9 for depression and the GAD-7 for anxiety, each taking under two minutes to complete. Your answers help your provider identify concerns you might not bring up on your own.
Screenings That Change With Age
The physical exam and blood work stay fairly consistent from year to year, but the screenings layered on top shift as you get older. Here’s a general timeline for the major ones:
- Cholesterol: Screening typically begins in your 20s for people with risk factors and becomes routine for most adults by age 35 to 40.
- Cervical cancer: Pap smears are recommended every 3 years starting at age 21. From age 30 to 65, you can switch to testing every 5 years if HPV testing is included.
- Mammograms: Annual breast cancer screening starts at age 40, including 3D mammography.
- Colorectal cancer: Screening begins at age 45, with a colonoscopy every 10 years being one of several options. If you use a stool-based test and it comes back positive, a colonoscopy follows within a year.
- Bone density: Screening for osteoporosis starts at age 65, repeated every two years. People with risk factors may start earlier.
Your provider won’t necessarily perform all of these during the checkup itself. Some, like mammograms and colonoscopies, are scheduled separately. But the checkup is where your provider reviews what you’re due for and puts in the orders.
What’s Different for Women
A well-woman visit may include a pelvic exam and clinical breast exam, but these aren’t automatic every year. Current guidelines from the American College of Obstetricians and Gynecologists recommend performing them when your medical history or symptoms call for it, rather than as a blanket annual requirement. Cervical cancer screening follows its own schedule (every 3 to 5 years depending on the testing method and your age), so you won’t necessarily need a Pap smear at every visit.
Your provider will also ask about your reproductive plans. This isn’t just about contraception. It helps guide decisions about which tests, vaccines, and medications are appropriate. For example, the RSV vaccine is now recommended during pregnancy on a seasonal basis.
What’s Different for Men
There’s no equivalent of the well-woman visit that’s widely standardized for men, but a few male-specific topics come up. Prostate cancer screening using a PSA blood test is a conversation, not an automatic order. Guidelines recommend that men between 55 and 69 discuss the benefits and risks with their provider and make a shared decision based on individual risk factors like family history. Routine testicular exams by a provider are no longer broadly recommended because testicular cancer is rare and treatment is highly effective even when caught at later stages.
Vaccines Your Provider Will Review
Your checkup is a good time to make sure your immunizations are current. The specific vaccines depend on your age and health status, but the most common ones your provider will check include:
- Flu shot: One dose annually for all adults.
- COVID-19: One or more doses of the current season’s updated vaccine, with additional doses recommended for adults 65 and older.
- Tetanus booster: One dose every 10 years.
- Shingles vaccine: Two doses starting at age 50.
- Pneumococcal vaccine: Recommended for adults 65 and older, or younger adults with certain health conditions.
- HPV vaccine: Available through age 45 for those who weren’t vaccinated earlier.
- Hepatitis A and B: Catch-up doses if you were never vaccinated.
Your provider will review your vaccination history and recommend any you’re missing or due to receive.
How to Prepare
Beyond fasting for blood work if instructed, a little preparation makes the visit more productive. Bring a list of all medications, vitamins, and supplements you take, including doses. Write down any symptoms or health changes you’ve noticed since your last visit, even minor ones you think might not matter. If you have family members who were diagnosed with cancer, heart disease, or diabetes, note their ages at diagnosis. Your family history directly influences which screenings your provider recommends and when.
If you’re seeing a new provider, request that your medical records be transferred ahead of time. Having your previous lab results, imaging, and vaccination records available prevents duplicate testing and gives your new provider the full picture from the start.
