44: Feeling Off but Labs Are 'Normal'? – The Best Tests Your Doctor Isn’t Running with Dr. Aaron Hartman
20 Nov 2025 · 3 min
Dr. Aaron Hartman explains three blood tests most doctors skip: Omega-3 levels, high-sensitivity CRP, and vitamin D. Each reveals inflammation, cardiovascular risk, or immune problems that standard labs miss. He also covers B12, folate, and homocysteine as markers of deeper metabolic health.

Up to a third of Americans have deficiency in omega 3 fatty acids. They're super important for anti inflammation, cardiovascular health, insulation of your nerves. Just taking fish oil supplement every day can actually lower your risk for sudden cardiac death up to 50% which is outstanding. Crazy number if your omega 3 levels are low, you have the same risk for heart disease as a smoker with normal Omega 3 levels. Simple test to do, easy to fix Foreign. What are the three tests that your doctor should be ordering on you, but they're not? That's what we're going to talk about today. We started a new series launching on the end of the week where we talk about a topic that people have asked me on social media, Instagram, in the office newsletter. So we're trying to answer people's questions here and this week we're talking about what the three tests your doctor isn't ordering on you, but they should be. What are those tests? Why are they important? The first one is an Omega 3 level check called Omega check. So why is this important? First of all, up to a third of Americans have deficiency in omega 3 fatty acids. They're super important for anti inflammation, cardiovascular health, insulation of your nerves. Just taking fish oil supplement every day can actually lower your risk for sudden cardiac death up to 50% which is outstanding. Crazy number we use fish oils that treat high cholesterol particle numbers to treat elevated triglycerides which are part of metabolic syndrome, mega 3s super super critical and taking them if your mega 3 levels are low. This is a crazy statistic. If your mega 3 levels are low, you have the same risk for heart disease as a smoker with normal mega 3 levels. So one way to think about these is they're as beneficial for your health as smoking is bad. That's a crazy statistic. Simple test to do, easy to fix. The next thing is an hscrp, also known as a high sensitivity or cardiac signature crp, which is important for heart health. This being elevated is associated with an increased risk for heart disease as well as neurovascular disease that usually shows up, cognitive decline, dementia, things like that. Basic tests like $2025 to do can be done by pretty much all of your major labs. When this is when people talk about inflammation, you know, inflammation being the cause of, you know, all diseases, inflamma, aging, all these kinds of things. The HSCRP is one of the primary ways we can actually look at this. It's something that also can be easily addressed as well. We when it's elevated, it's usually associated with some kind of occult or hidden infection. Could be dental or oral periodontis, periodontitis, gingivitis, infected root canals. Cavitations could be related to gut issues. If you had sibo bacterial overgrowth. Some people with chronic infections, chronic Lyme, et cetera, will have elevated HSCRP levels. It's a marker for interest in your small arteries. It can be treated lowered by finding those infections, those issues, treating it. There's nutritional support can be used for as well, but it's hugely important. It's one of the three major markers, particularly in women for heart disease. An interesting study came out last fall, actually sponsored by the NIH, looking at heart disease in women and showed three markers. Your HSCRP, your lipoprotein little A and your LDL particle number. You could predict a female's 30 year risk for heart disease. Now, I mentioned those other markers today, but HSCRP is one of the three markers that allows you to actually have a window into a female's risk for heart heart disease.
Have you ever lost trust in your own body or in the doctors who were supposed to help you heal? It happens to millions of people who are stuck in the cycle of prescriptions, tests and more questions than answers. That's why Dr. Aaron Hartman wrote his new book Uncurable.

Foreign lab test that your doctor should be ordering Isn't this one's a staple. It's a vitamin D level. Unfortunately, it's still not done by a lot of people. Vitamin D affects your body's ability to switch from fighting your innate immune system, which is the first part of your immune system to turn on, to making antibodies. It was one of the major risk factors for people actually dying from COVID If you're omega. Sorry, if your vitamin D level was over 50, you had less than a 0.005 chance of of dying from COVID Low vitamin D levels are associated with increased risk for heart disease, metabolic syndrome, inflammation, aging. As you get older, your vitamin D levels go down. It's super important for your body's ability, your, your immune system to regulate antibody production, regulate self and non self. It's also important for sugar control. Pretty much all my diabetic patients, vitamin D levels are low, all immune patients. And it's a really simple thing to check and it's easy to address. So these are the three major labs that everybody should get from the primary provider. Easy, easy to address. Now are there other tests you could look at that might give you, you know, bonus section? Right. Well, what's some other tests that are super easy to do that have a huge benefit? I tend to like to get B12 and folic acid levels on patients as well. Why is that? I use those as surrogate markers for other B vitamin deficiencies. According to the US RDA, USDS, 40 to 60% of Americans are deficient in any 1B vitamin. Now it's expensive to check all those levels. You know, you can't do. You have to see a functional provider, et cetera, et cetera. For years and years, I used folic acid and a B12, which can easily be covered by insurance for a whole host of diagnoses as surrogate markers. If your B12 is low or low normal and your folic acid is low, you probably have B1, B2, B3, B6, you probably have other B9, pantothenic acid, biotin, you probably have other deficiencies. So I use them as a surrogate marker. Again, a super easy thing to check. Homocysteine is the last bonus lab I want to talk about. It's a common lab. It's of Dale Brunson's labs for looking at dementia. It's part of Dr. Mark Houston's labs for looking at risk for cardiovascular disease. It's a marker for methylation, which is your body's ability to turn on or off DNA. When homocysteine levels are really low, you have an increased risk associated with an increased risk for cancer. When your homocysteine levels are elevated, you have an increased risk for strokes and heart attacks. I remember this is probably 15 years ago. One of my patients had had several strokes and this was when I was still doing a lot of primary care. And she was a smoker, she drank, you know, she had three strokes on medication. Nothing was helping. Her homocysteine level was 30 and just by getting that less than 15, she stopped having strokes. It's a super important thing, easy to address, easy to fix.
