A general check-up is a routine visit to your primary care provider designed to assess your overall health, catch potential problems early, and update preventive screenings. Unlike a sick visit where you go in with a specific complaint, a check-up happens when you’re feeling fine. For most healthy adults, the recommendation is once a year regardless of age, starting in your 20s.
What Happens During a Check-Up
The visit typically starts before anyone touches a stethoscope. Your provider will review your medical history, ask about any new diagnoses or surgeries since your last visit, and go over your family health history. If a parent or sibling has been diagnosed with heart disease, diabetes, or certain cancers, that information shapes which screenings you need and how early they should start. You’ll also be asked about all medications and supplements you currently take, including dosages.
Next come your vital signs. A nurse or medical assistant will measure your blood pressure, heart rate, breathing rate, and temperature. For a healthy adult at rest, normal ranges look like this:
- Blood pressure: between 90/60 and 120/80 mmHg
- Heart rate: 60 to 100 beats per minute
- Breathing rate: 12 to 18 breaths per minute
- Temperature: 97.7°F to 99.1°F, averaging 98.6°F
Your height and weight will be recorded to calculate your BMI. Then your provider performs a physical examination, which usually includes listening to your heart and lungs, checking your abdomen, examining your ears, nose, and throat, and testing basic reflexes. The whole visit often lasts 20 to 40 minutes depending on how much there is to discuss.
Blood Work and Lab Tests
Depending on your age and risk factors, your provider may order blood work as part of the visit. The most common tests include a blood sugar test, a cholesterol panel (which measures both cholesterol and triglycerides), and sometimes a basic metabolic panel that checks kidney function and electrolyte levels. Liver function tests may also be ordered if there’s a reason to check.
Several of these tests require fasting, meaning you can’t eat or drink anything except water for 8 to 12 hours beforehand. Blood sugar, cholesterol, and triglyceride tests all fall into this category. Your provider’s office should tell you ahead of time whether fasting is needed, but if you’re unsure, ask at least a full day before your appointment so you can prepare. Bringing a snack to eat right after your blood draw is a good idea.
Preventive Screenings by Age
One of the most valuable parts of a check-up is staying current on screenings that detect serious conditions before symptoms appear. Blood pressure screening is recommended for all adults 18 and older. If your reading comes back elevated in the office, your provider may ask you to take additional readings at home or at a pharmacy before making any treatment decisions, since a single high reading in a clinical setting isn’t always accurate.
Cancer screenings follow specific age-based timelines for people at average risk:
- Cervical cancer: Pap test every 3 years starting at age 21. From age 30 to 65, you can switch to a Pap test every 3 years, an HPV test alone every 5 years, or both tests together every 5 years.
- Breast cancer: Mammography every 2 years. The recommended starting age was expanded in 2024 to include ages 40 to 49, down from the previous threshold of 50.
- Colorectal cancer: Screening from age 45 to 75 (previously starting at 50). Options include a colonoscopy every 10 years, a stool-based test every 1 to 3 years depending on the type, or a flexible sigmoidoscopy every 5 years.
Your provider will recommend the right schedule based on your age, sex, and personal or family history. People with higher risk factors may need to start certain screenings earlier or have them more frequently.
Mental Health Screening
Check-ups increasingly include a brief mental health assessment. Many primary care offices now use short questionnaires to screen for depression and anxiety. These are simple forms where you rate how often you’ve experienced symptoms like low mood, trouble sleeping, or persistent worry over the past two weeks. Your answers are scored to flag whether further evaluation might be helpful. This screening is routine and doesn’t mean your provider suspects a problem. It’s treated the same way as checking your blood pressure: a quick baseline measurement that can catch something you might not have brought up on your own.
Vaccine Review
Your check-up is also when your provider reviews whether you’re up to date on vaccinations. Adults need more vaccines than many people realize. A flu shot is recommended every year for all adults. A tetanus booster is needed every 10 years. Beyond those basics, the CDC schedule includes vaccines for shingles (starting at age 50), pneumonia (for adults 65 and older or those with certain conditions), hepatitis A and B, and HPV (through age 26, or up to 45 in some cases). COVID-19 vaccination recommendations are updated seasonally. If you’ve missed any childhood vaccines or don’t have records, your provider can help figure out what you still need.
How to Prepare for Your Visit
A little preparation makes the appointment more productive. Before you go, write down a complete list of every medication and supplement you take, including dosages. If you track your blood pressure, sleep, or diet with an app or device, bring that data along. Note any changes since your last visit: new symptoms you’ve noticed, vaccines you received elsewhere, or procedures you had with a specialist.
Think about your family health history, too. Your provider will want to know about conditions affecting your parents, grandparents, siblings, or children, particularly heart disease, diabetes, and cancer. If you’re not sure, it’s worth asking family members before your appointment. And if blood work is planned, confirm whether you need to fast so you don’t have to reschedule.
What It Costs
Under the Affordable Care Act, most health insurance plans are required to cover a set of preventive services at no cost to you. This includes screenings, immunizations, and wellness visits when provided by an in-network provider. You won’t pay a copayment or coinsurance for these covered services, even if you haven’t met your deductible. The key requirement is staying in-network. If your provider orders additional tests or addresses a specific health concern during the same visit, that portion may be billed separately and could involve cost-sharing, so it helps to ask beforehand what’s covered as preventive versus diagnostic.
