Routine blood work, age-based screenings, and lifestyle-specific labs can turn a short annual visit into a useful review of your health when you ask for them by name. A complete blood count, lipid panel, and glucose or A1C test form the floor, while mammograms, colonoscopies, and TSH round out the picture based on your age, sex, and risk factors.
The sections below cover routine panels, screenings that shift with age and sex, tests worth requesting beyond the basics, insurance coverage, and how to advocate for yourself during the appointment.
Why the Default Physical Often Leaves Gaps
An annual exam usually opens with height, weight, blood pressure, and a short chat about how you feel. After that, many clinicians order a reflex panel: complete blood count, metabolic panel, lipid panel, sometimes a glucose check. That template works for a healthy adult with no complaints, but it was never designed to catch everything you might face.
Time is the hidden variable. Preventive counseling takes a documented chunk of a twelve- to twenty-minute visit, so anything outside the template depends on you raising it. Silent problems like prediabetes, mildly elevated cholesterol, and Stage 1 hypertension produce no symptoms, which is exactly why they slip past a visit focused only on complaints. Asking informed questions signals to your clinician that you want shared decision-making, not just a clean bill of health.
Preventive care earns its keep by catching these quiet shifts before they turn into prescriptions or referrals. Screening schedules should be built around your age, sex, and risk factors because the right test for a thirty-five-year-old woman differs sharply from the right test for a sixty-year-old man with a diabetic parent. That framing aligns with guidance from the U.S. Preventive Services Task Force (USPSTF).
Routine Blood Work Every Adult Should Expect
Baseline labs form the floor of any useful physical. These are the tests a primary care physician almost always orders, and understanding what each one screens for helps you track your own trends over time.
The Standard Panel
- Complete blood count (CBC): Screens for anemia, infection, and abnormal blood cell counts that can hint at nutritional gaps or immune issues.
- Comprehensive metabolic panel (CMP): Evaluates kidney function, liver enzymes, electrolytes, and blood sugar in one draw.
- Lipid panel: Measures total cholesterol, LDL, HDL, and triglycerides to assess cardiovascular risk.
- Fasting glucose or A1C: Screens for prediabetes and diabetes; A1C or fasting glucose is recommended starting at age 35 for adults who are overweight or carry other risk factors.
How Often These Tests Repeat
A normal-risk adult with no family history can usually repeat the lipid panel every four to six years. Once risk factors appear, like elevated BMI, blood pressure trending upward, or a first-degree relative with early heart disease, the cadence compresses to once a year or even more often. Glucose screening follows a similar pattern: every three years for normal-risk adults, sooner when weight, activity level, or family history shifts.
Screenings That Shift With Age, Sex, and Family History
Routine blood work covers only part of the picture. The other half of a thoughtful physical is the age- and sex-based screenings that catch cancer, bone loss, and organ-specific problems before they cause symptoms.
Vital Signs and Basic Checks
Blood pressure deserves its own mention because it gets measured at almost every visit yet often gets dismissed if the reading feels “close enough.” A normal reading under 120/80 mmHg should be rechecked at least every two years; readings in the elevated or Stage 1 range warrant annual checks or sooner follow-up. Body mass index, while imperfect, gives a quick read on weight-related risk.
Waist circumference adds another useful data point, especially for adults whose BMI lands in the borderline category.
Age- and Sex-Based Screenings
| Screening | Who It’s For | Typical Starting Age or Interval |
|---|---|---|
| Mammogram | Women | Every 1–2 years starting at 40 or 50, depending on guideline and risk |
| Pap smear / HPV test | Women | Every 3–5 years from age 21 through 65 |
| Colonoscopy or stool-based screening | All adults | Starting at 45, repeated per result and modality |
| PSA discussion | Men | Shared decision-making starting around age 50 (earlier with elevated risk) |
| Bone density (DEXA) scan | Women, and men with risk factors | Starting at 65 for women, sooner with fracture history or steroid use |
| Hearing and vision checks | All adults | Baseline at 40–50, then periodic |
Thyroid, Hormone, and Skin Checks
TSH (thyroid-stimulating hormone) testing is often suggested for women over 60 or anyone experiencing fatigue, unexplained weight shifts, hair changes, or persistent cold intolerance. Because symptoms overlap with stress, poor sleep, and perimenopause, a TSH result gives you a clean ruling-out data point rather than a diagnosis. Skin checks belong in this category too.
A full-body skin exam takes five minutes and catches early melanomas in adults with fair skin, significant sun exposure, or a personal history of sunburns. Ask whether your clinician performs one or whether you need a dermatology referral.
Tests Worth Requesting Beyond the Standard Panel
Some useful tests sit outside the routine panel, and the decision to order them depends on your lifestyle, family history, and symptoms you bring up yourself. None of these are necessary for everyone, but several pay off in specific situations.
Nutritional and Inflammatory Markers
- Vitamin D (25-OH): Frequently low in adults with limited sun exposure, darker skin tones, or digestive conditions like IBS or celiac disease.
- Ferritin: Useful when fatigue is in play; ferritin drops before hemoglobin does, so a “normal” CBC can mask early iron deficiency.
- hs-CRP (high-sensitivity C-reactive protein): An inflammatory marker that adds context to cardiovascular risk, especially when family history of early heart disease is present.
- Hemoglobin A1C: Even when fasting glucose looks fine, A1C reflects average blood sugar over three months and catches prediabetes earlier.
Infection and Sexual Health Screenings
At least one-time HIV, hepatitis C, and syphilis screening is recommended for adults, with repeat STI panels (chlamydia, gonorrhea, HIV, syphilis) for anyone with new or multiple partners. Asking for a full STI screen during a physical removes the awkwardness of a separate clinic visit and keeps the rest of your preventive care on schedule. That guidance reflects standing recommendations from the CDC.
Mental Health and Sleep
Sleep changes and mood shifts quietly reshape blood pressure, blood sugar, and cholesterol readings on every other metric in this checklist. A short depression screening (PHQ-9) and a sleep quality conversation should sit alongside cholesterol checks in importance, since poor sleep raises blood pressure, blood sugar, and inflammation simultaneously. If something has changed for you in the last year, mention it; the right referral or follow-up often starts there.
Insurance Coverage and Out-of-Pocket Costs
Many patients hesitate to request extra tests because of cost confusion, even though most insurance plans must cover a wide range of preventive screenings at zero out-of-pocket expense. That requirement sits in the Affordable Care Act (ACA).
What Insurance Typically Covers
Plans must cover USPSTF “A” and “B” rated preventive services when delivered by an in-network provider. That list includes blood pressure checks, lipid panels, certain cancer screenings (mammograms, colonoscopies, Pap smears), immunizations, and diabetes screening for at-risk adults. Well-woman and well-man visits fall under the same umbrella, so the office visit itself is usually covered.
What Often Bills Separately
Tests ordered outside preventive guidelines (vitamin D, expanded hormone panels, ferritin without anemia, hs-CRP without cardiovascular symptoms) frequently generate separate lab billing. A “non-covered” test can still be useful; the question is whether the price tag fits your budget and whether the result will actually change a decision you are about to make.
Calling your insurer before the visit, with the specific CPT codes your doctor’s office can provide, clarifies what is fully covered, what requires cost-sharing, and what falls under your deductible. A ten-minute phone call often saves a hundred-dollar surprise.
How to Advocate for Yourself at the Appointment
The most useful physicals happen when you arrive prepared. A short written list, focused on the last twelve months and your family history, beats trying to remember details while the clinician types.
What to Bring
- A one-page health summary: Current medications, allergies, recent symptoms, and major family diagnoses (parents, siblings, grandparents).
- A short list of questions: Two to four specific items you want answered before you leave.
- Prior lab results if available: Tracking trends matters more than any single number.
- An updated list of supplements: Several common over-the-counter products interact with prescription decisions.
How to Phrase Requests
Collaboration language works better than demands. A phrase like “Given my family history of thyroid issues, would a TSH test make sense for me?” invites your doctor into shared decision-making rather than putting them on the defensive. Ask which tests are being ordered, what each one screens for, and how results will reach you, through a phone call, the patient portal, or a follow-up visit.
Request a copy of every lab result with the reference ranges printed alongside your numbers. A single lipid panel tells you less than three panels plotted over time. Tracking your own data turns each annual visit into a real conversation about trajectory rather than a snapshot that may or may not be meaningful.
The Bottom Line
The right tests at your physical depend on your age, sex, family history, and the symptoms you actually mention in the room. Bring a written list, ask which preventive screenings your insurance covers, and request your lab results so you can track trends over time. A prepared patient walks out with a personalized health review instead of a generic clearance.
FAQ
Which blood tests should you request at your yearly physical?
Your standard annual panel includes a CBC, CMP, lipid panel, and either fasting glucose or A1C. Add vitamin D, ferritin, or hs-CRP based on symptoms, family history, or risk factors you bring up during the visit.
Do you need to fast before lab work at a physical exam?
You will need to fast for eight to twelve hours for an accurate fasting glucose and sometimes for triglycerides, though non-fasting lipid panels are increasingly accepted. Ask your doctor’s office which of your specific tests require fasting so you do not have to repeat the draw.
What cancer screenings should you ask about during a physical?
Your cancer screenings depend on your age and sex. Mammograms, Pap smears, colonoscopies (or stool-based tests), and PSA conversations each follow their own guideline. Your doctor should walk through which apply to you this year.
How do you know which preventive screenings your insurance covers?
Call your insurer with the specific CPT codes from your doctor’s office and ask whether each test is covered as preventive under the ACA. A quick pre-visit call prevents surprise bills and clarifies your out-of-pocket exposure.
What is the difference between a wellness visit and a physical?
Most insurance plans cover a wellness visit that focuses on preventive services and screenings at no cost, whereas a physical usually adds a head-to-toe exam and addresses new or ongoing problems. The two overlap, but insurance billing treats them differently, so clarify which one you are scheduling.
