Top 10 Blood Tests to Ask Your Doctor to Run

"Everything Looks Normal." So Why Do You Still Feel Terrible?
If you have ever sat across from a doctor, heard the words "your labs are normal," and walked out still exhausted, still foggy, still inflamed, still not yourself, you are not imagining it. And you are not alone.
Routine blood work was never designed to catch the whole picture. It was designed to catch disease once it has already arrived. Which means by the time a standard panel flags something, your body has usually been waving a flag of its own for years.
The good news is you get to ask for more. You just have to know what to ask for.
The Check Engine Light Nobody Is Looking At
Most people know their glucose. Most people know their A1C. Almost nobody knows their fasting insulin. And that is a problem, because insulin can rise years before blood sugar ever budges.
Think of it as the check engine light that comes on long before the engine actually stalls. By the time glucose looks off, insulin resistance has often been quietly building for a decade. It is one of the most overlooked labs in medicine, and it is exactly the kind of marker routine panels leave out.
Same Lab, Completely Different Story
Here is one that surprises almost everyone. Ferritin is not just an iron test. Low ferritin can leave you running on empty, exhausted, foggy, losing hair. High ferritin can point toward inflammation simmering somewhere else in the body entirely. Same test. Two completely different stories, depending on the context around it.
And that is really the heart of it. A number by itself does not tell you much. A number in context tells you almost everything.
One Frame Does Not Make a Movie
If your thyroid has ever been checked with a single TSH and called a day, you have only seen one frame of a much longer film. Your thyroid touches your energy, your mood, your metabolism, your hair, your temperature, your ability to think clearly. Evaluating it with one number is like trying to summarize an entire movie from a single still image.
There is a full conversation your thyroid deserves, and most people never get invited to have it.
Your Body Whispers Before It Screams
Fatigue. Brain fog. Weight that will not budge. Anxiety. Hair loss. Poor sleep. These are not random. They are your body whispering long before it has to scream. The question is never how fast we can quiet the symptom. The question is what your body is actually trying to tell you.
That is the whole philosophy behind this list. Ten labs. Not because they are the only ones that matter, but because together they start turning whispers into answers.
The List
So if you asked me, "Dr. Jen, what should I have my doctor run?" Here is exactly where I would start.
Fasting Insulin — the early warning sign that shows up years before glucose does
HS-CRP — a marker of inflammation, the check engine light for something going on beneath the surface
Ferritin — your iron savings account, and a clue to far more than iron alone
Complete Thyroid Panel — TSH, free T4, free T3, reverse T3, and antibodies, not just TSH alone
Vitamin B12 — essential for nerve function, brain health, and energy, and rarely optimized on a Western medicine scale
Vitamin D — a hormone, not a vitamin, and one of the first things I check when a thyroid looks off
Omega-3 Index — what your body has actually absorbed, not just what you have been eating
ApoB — a far more precise read on cardiovascular risk than LDL alone
Complete Blood Count — a familiar test that holds far more information than most people realize
Comprehensive Metabolic Panel — liver, kidneys, electrolytes, and blood sugar, all in one
That is the list. But a number without context is just a number.
Want to Go Deeper?
In the latest episode of the Mindful Healing podcast, Top 10 Blood Tests for Optimal Health, I walk through why I order each one of these, what "optimal" actually looks like versus what your lab report calls "normal," and the patterns I look for that most doctors are never trained to connect.
Go listen. Then go make a list for your next doctor's appointment.
Remember, normal does not always mean healthy. Your body is remarkably intelligent, and it has been trying to talk to you the whole time.
Wishing you love, light, and continued healing.
