The Short Answer
Most doctors only order a CBC, a basic metabolic panel, and a standard lipid panel. This bare-minimum approach waits for you to get sick before sounding the alarm.
To actually monitor your health, you need to add specific longevity and metabolic markers. An optimal annual panel includes fasting insulin, a full thyroid panel, vitamin D, and inflammatory markers like CRP.
Why This Matters
The standard medical system operates on a "sick care" model, not a preventative one. Insurance companies dictate what your doctor can order, limiting tests to the absolute cheapest options.
By the time standard markers like fasting glucose go out of range, the damage is already done. Metabolic dysfunction develops for up to a decade before it shows up on a standard physical. What Is Fasting Insulin And Why Does It Matter
You don't have to settle for the standard insurance-approved panel. You can either demand specific add-ons from your primary care doctor or bypass them entirely using direct-to-consumer labs. What Are The Best Direct To Consumer Lab Testing Services
What's Actually In A Standard Panel
Your doctor's default blood work gives a decent high-level overview, but leaves massive blind spots. Here is exactly what your insurance covers during a routine physical.
- Complete Blood Count (CBC) — Measures red cells, white cells, and platelets to check for basic infections or anemia. What Is A Cbc Blood Test
- Comprehensive Metabolic Panel (CMP) — Looks at kidney function, liver enzymes, electrolytes, and basic blood sugar. What Is A Comprehensive Metabolic Panel
- Standard Lipid Panel — Checks total cholesterol, LDL, HDL, and triglycerides, but misses advanced cardiovascular risk factors.
- TSH (Thyroid Stimulating Hormone) — A surface-level check of thyroid function that misses autoimmune thyroid issues. What Thyroid Tests Should You Ask For
What to Look For
If you want to move from surviving to thriving, you need to request specific upgrades to your annual blood work. Ask your doctor for these proactive health markers to get a complete picture of your health. What Labs Should You Watch Closely
Green Flags (Must-Add Markers):
- Fasting Insulin & HbA1c — Fasting glucose is a late-stage indicator. Insulin and HbA1c reveal the true state of your metabolic health years earlier. What Is Hba1c And What Is A Good Level
- ApoB & Lp(a) — These are the true drivers of plaque buildup and cardiovascular disease, making them far more accurate than standard LDL.
- High-Sensitivity CRP (hs-CRP) — Measures systemic inflammation, which is the root cause of almost every chronic disease. What Is Crp And What Does It Tell You
- Comprehensive Thyroid Panel — Request Free T3, Free T4, and thyroid antibodies to catch dysfunction that TSH alone misses. What Is The Difference Between Tsh T3 And T4
- Vitamin D & Ferritin — Over 40% of Americans are deficient in Vitamin D, and ferritin reveals low iron stores before you actually become anemic. Should You Test Your Vitamin D Levels What Is Ferritin And Why Is Low Ferritin A Problem
- Homocysteine — A crucial marker for cardiovascular risk, brain health, and B-vitamin absorption. What Is Homocysteine And Why Should You Test It
Red Flags (Why Standard Panels Fail):
- "Normal" Range Reliance — Lab reference ranges are based on the average sick American, not optimal health.
- Refusal to Test — If your doctor refuses to order basic preventative markers, it’s a sign they are bound by strict insurance guidelines.
The Best Options
If your doctor won't order a comprehensive panel, you can order it yourself. Direct-to-consumer testing is now cheaper and more accessible than ever. What Are The Best Direct To Consumer Lab Testing Services
| Brand | Product | Verdict | Why |

| Function Health | Function Membership | ✅ | Tests 100+ biomarkers, including all optimal add-ons, for under $500 a year. What Does Function Health Test For |
| Marek Health | Custom Panel | ✅ | Lets you build an à la carte blood panel with no membership required. |
| Quest Diagnostics | Standard Physical | ⚠️ | Good for basic CBC/CMP, but you have to pay out of pocket for longevity markers. |
The Bottom Line
1. Don't settle for the bare minimum. A standard physical is designed to catch late-stage disease, not optimize your health.
2. Ask for the metabolic and thyroid upgrades. Fasting insulin, ApoB, and a full thyroid panel are non-negotiable for a true health baseline. What Labs Should You Watch Closely
3. Bypass the middleman if needed. If your doctor says no, use a direct-to-consumer lab to get the data you deserve.
FAQ
Should women test their hormones annually?
Most standard physicals do not check sex hormones unless you report specific symptoms. Women dealing with fatigue, weight resistance, or mood changes should request a full hormone panel. Should Women Test Their Hormones
Does insurance cover advanced blood tests?
Usually, no. Insurance companies label preventative markers like fasting insulin and ApoB as "medically unnecessary." You will likely have to pay out of pocket or use a direct-to-consumer lab service.
How often should you get blood work done?
Once a year is the bare minimum for healthy adults. If you are actively trying to fix a deficiency, reverse insulin resistance, or optimize hormones, you should test every 3 to 6 months. How Often Should You Get Blood Work Done
