Your annual physical came back normal. Again. Same basic panel, same "everything looks fine," same feeling that something is off that the paperwork isn't catching.
I want to walk you through why that happens — not because your doctor did anything wrong, but because a standard annual physical is built to catch a specific set of problems, and it's not designed to explain fatigue, bloating, or weight that won't move.
What a Standard Physical Actually Screens For
A typical annual physical usually includes a CBC (complete blood count), a basic metabolic panel, and sometimes a lipid panel and TSH. These are genuinely important — they catch anemia, kidney and liver function issues, diabetes risk, and major thyroid dysfunction.
What they're not built to do is explain a pattern of fatigue, inflammation, or metabolic symptoms in someone whose values fall inside a wide "normal" range. In the ICU, I learned that a number inside a reference range isn't automatically the right answer for the patient in front of you — it's a starting point, not a conclusion.
Lab Tests Your Doctor Doesn't Run (and Why)
This isn't a criticism of primary care — most physicians are managing volume and insurance constraints that don't leave room for the deeper panels below.
A Full Thyroid Panel, Not Just TSH
TSH alone can miss real dysfunction. Free T3, Free T4, and thyroid antibodies fill in a picture that TSH by itself doesn't.
Ferritin, Not Just Hemoglobin
A normal hemoglobin doesn't rule out low iron stores. Ferritin can sit low-normal while still being too low to support energy production.
Fasting Insulin, Not Just Fasting Glucose
Glucose can look normal for years while insulin is already elevated — insulin resistance often shows up here before it shows up on a standard glucose test. (Medscape workup overview)
Inflammatory Markers
Markers like hs-CRP aren't part of a standard panel but can flag low-grade inflammation contributing to fatigue and other symptoms.
Comprehensive Hormone Panels
For women in perimenopause or dealing with cycle-related symptoms, a single hormone snapshot rarely tells the full story the way a more complete panel can.
What This Isn't
This isn't about running every test available or chasing numbers for their own sake. What the research generally suggests, and what I see with patients, is that a more complete panel — chosen based on your actual symptoms — gives a fuller picture than a standard physical alone. It's not a replacement for your primary care relationship; it's an addition to it.

How This Works in My Practice
I review labs alongside Dr. Jean Carlos Jimenez, MD, who holds prescribing authority and oversees clinical decisions in the practice. Testing gets ordered based on your specific symptoms, not a one-size-fits-all package.
FAQ
Why doesn't my doctor run these tests? Time, insurance coverage, and standard-of-care guidelines all play a role — it's rarely about your doctor missing something, more that a typical visit isn't structured for this level of detail.
Are these tests covered by insurance? This varies by test and provider.
How do I know if I need a fuller panel? Persistent fatigue, unexplained weight changes, bloating, or feeling "not like yourself" despite normal basic labs are common reasons to look further.
Is more testing always better? No — the goal is targeted testing based on your symptoms, not testing for its own sake.
