17 Sep What Labs Should I Ask for at My Annual Physical?
Most annual physicals include far less bloodwork than people assume, and that gap is exactly why so many patients leave their appointment without answers to problems they came in with. A standard visit typically covers a Complete Blood Count and a Comprehensive Metabolic Panel by default, but a lipid panel, thyroid testing, vitamin D, and blood sugar screening are often left out unless you specifically ask, or unless your provider already knows you have a relevant risk factor. Knowing which labs exist, what each one actually checks, and when it makes sense to request them beyond the default panel puts you in a much better position at your next visit than hoping your doctor happens to order everything relevant.
At EOWC Medical in Tulsa, Oklahoma, we build a physical around more than the default panel, because catching a thyroid, blood sugar, or vitamin D issue early is far easier than treating it after it becomes symptomatic.
What’s Actually in the Standard Panel
A Complete Blood Count, or CBC, checks red cells, white cells, hemoglobin, hematocrit, and platelets, and it is one of the most useful screening tools for anemia, infection, or a blood disorder. Mayo Clinic’s overview of the complete blood count describes it as a baseline test most healthy adults have done annually as part of routine care. Alongside the CBC, a comprehensive metabolic panel measures fourteen separate markers, including glucose, kidney function, liver enzymes, and electrolytes, giving a broad snapshot of metabolic health in a single blood draw.
The Labs That Are Easy to Miss
A lipid panel, which measures total cholesterol, LDL, HDL, and triglycerides, is not always included by default. The CDC recommends most healthy adults have their lipid panel checked every four to six years, with more frequent testing recommended for anyone with heart disease, diabetes, or a family history of high cholesterol. If any of those apply to you, it is worth explicitly asking for a lipid panel at your visit rather than assuming it happens automatically every year.
Thyroid testing, specifically TSH, falls into a similar category. There is no universal government mandate for annual thyroid screening in people without symptoms, but thyroid dysfunction is common, often silent, and inexpensive to test for, which is why many primary care providers include it in a routine wellness panel anyway. If you have fatigue, unexplained weight changes, hair loss, or mood changes, or a personal or family history of thyroid disease, specifically asking for a TSH test is reasonable even without a formal recommendation requiring it.
Vitamin D is not part of the standard panel and insurance may not cover it without a documented reason on the order. According to the NIH’s fact sheet on vitamin D deficiency, people with limited sun exposure, darker skin, obesity, or malabsorption conditions are more likely to be deficient, which is worth mentioning if you have any bone, joint, or persistent fatigue symptoms that have not been explained otherwise.
Screening Tests Tied to Age and Risk Factors
Some labs are recommended based on age or specific risk profiles rather than being part of every physical. Diabetes and prediabetes screening using fasting glucose or HbA1c is recommended for adults between 35 and 70 who are overweight or obese, with a three-year re-screening interval reasonable if results come back normal. For men, the PSA screening guidance from the CDC frames prostate cancer screening between ages 55 and 69 as an individualized decision made after discussing the benefits and harms with your doctor, rather than a test that should be automatically ordered for every man in that age range.
| Lab Panel | What It Checks | Who Should Ask |
|---|---|---|
| CBC | Red cells, white cells, hemoglobin, platelets | Most adults, annually |
| CMP | Glucose, kidney function, liver enzymes, electrolytes | Most adults, annually |
| Lipid Panel | Total cholesterol, LDL, HDL, triglycerides | Every 4-6 years; more often with heart disease, diabetes, or family history |
| HbA1c / Fasting Glucose | Average or point-in-time blood sugar | Adults 35-70 who are overweight or obese |
| TSH | Thyroid function | Anyone with symptoms or family history; often included routinely |
| Vitamin D | Bone, immune, and muscle-related nutrient status | Limited sun exposure, obesity, malabsorption, or bone symptoms |
| PSA | Prostate cancer screening marker | Men 55-69, after discussing benefits and harms |
Why Choose EOWC Medical for Your Annual Physical
Our approach to an annual physical looks past whether a result technically lands inside a lab’s broad “normal” range and toward what an optimal range looks like for your age, symptoms, and goals. Two patients can both have a TSH or vitamin D result that is technically “normal” on paper while one of them is functioning noticeably better than the other, and that distinction is exactly what a preventive, functional-medicine lens is built to catch. Rather than defaulting to the same basic panel for every patient, we ask about your specific symptoms and risk factors up front and build the lab order around what is actually relevant to you, not just what is billed automatically. For Tulsa patients who have been told their labs are “fine” while still not feeling like themselves, that closer look is often where real answers start.
Our physical exams are built around this broader lab approach, and for patients with fatigue or mood changes, we often check for hormonal factors at the same visit.
Conclusion
The default annual physical panel, a CBC and CMP, covers a lot of ground, but a lipid panel, thyroid testing, vitamin D, and blood sugar screening are often left out unless you ask or unless a specific risk factor triggers them. Knowing what each lab checks and when it applies to you turns a routine visit into a genuinely useful screening tool. Reach out to our Tulsa provider team to build a lab panel around your actual health picture.

Frequently Asked Questions
What blood tests are typically included in a standard annual physical?
Most annual physicals include a Complete Blood Count and a Comprehensive Metabolic Panel by default. Many providers also add a TSH thyroid test even without symptoms, since thyroid dysfunction is common and easy to miss on history alone.
How often should I get a lipid panel, and at what age should I start?
Most healthy adults should have cholesterol checked every 4 to 6 years, starting in young adulthood, with more frequent testing for those with heart disease, diabetes, or a family history of high cholesterol. People with risk factors should ask for it annually rather than waiting the full interval.
Do I need a thyroid test every year, or only if I have symptoms?
There is no universal mandate for annual thyroid screening in asymptomatic average-risk adults, but it is commonly ordered as part of a routine wellness panel. Anyone with fatigue, weight changes, hair loss, or mood changes should specifically ask for it.
Should I ask my doctor to check my vitamin D level?
Vitamin D is not part of the standard panel and may not be covered without a documented reason. People with limited sun exposure, darker skin, obesity, or bone or joint symptoms should ask for it since deficiency is common in these groups.
What’s the difference between a fasting glucose test and an HbA1c test?
Fasting glucose measures blood sugar at a single point in time after fasting, while HbA1c reflects average blood sugar over roughly the past 2 to 3 months without requiring fasting. Screening with either test is recommended for adults 35 to 70 who are overweight or obese.
