Heads Up Health allows you to track the Bristol Stool Chart to help you identify problematic foods, supplements, digestive health and other lifestyle stressors. While it may seem foreign or unusual to examine what comes out of your body, it’s pretty important for improving or maintaining your health. The amount of time your food travels through your body can give you clues as to whether or not the fuel you’re putting into it is best serving you and if you’re able to digest and assimilate it well.

Thyroid function is a hotly debated topic in the low-carb world. While most people typically experience fat loss, better energy levels, and improved overall vitality on a low-carb diet, in some individuals, measurements of thyroid-related hormones suggest that a low carbohydrate intake might be having adverse effects on the thyroid gland. Is it possible that a way of eating that has such wonderful benefits for so much of the body could be harmful for the thyroid?
This is the fifth installment of a series exploring lab tests for people following low-carb diets. Due to the effects of the low-carb or ketogenic ways of eating on overall metabolism, interpreting certain lab tests requires a slightly different perspective compared to results from people following high-carb diets.
Previous posts have explored blood glucose testing, fasting insulin, and HOMA-IR (and remember: if you’d like to get some tests your doctor isn’t familiar with, or to test more frequently than your insurance will cover, this recent Heads Up Health post will show you how to order your own lab tests).
Keeping track of your numbers is an important step for anyone who wants to transform their health. Heads Up Health was created to empower you to manage all of your health data, including your lab test results, in one secure location.

We’ve covered a lot in our low-carb lab testing series so far. At this point, we felt it was time for a real-world case study to tie everything together. In this post we will take a look at my own experience ordering fasting glucose and fasting insulin tests, calculating my HOMA-IR score and tracking results in my Heads Up profile.

Low-carb lab testing – a case study
As we’ve explored in previous posts, there are many reasons why an individual may see normal blood glucose levels and still be at risk for metabolic issues down the road. One possible reason is because the body is over-compensating with insulin to keep blood sugar within normal ranges. I decided to put this to the test with my own data.
Yes, I regularly check my fasting blood glucose levels at home as part of my low-carb/ketogenic lifestyle. And yes, according to my glucometer, my blood sugar is within healthy ranges. But as we know, relying on just my glucometer (without a corresponding fasting insulin test), doesn’t always tell the full story. I felt it was an ideal opportunity for some self-directed n=1 experimentation. I was curious to see the fasting insulin data and calculate my own HOMA-IR score.
Step 1 – Ordering the tests
Unfortunately, many conventional doctors within the US will not order a fasting insulin test unless they suspect metabolic disease (or you have already been diagnosed with a metabolic disease). This doesn’t do much good for the person who is trying to be proactive. Even if you do successfully sweet talk your doctor into ordering the tests you want, there are no guarantees your insurance company will cover the cost of the test. Fighting with an insurance company over tests they won’t cover is enough to make a grown man (or woman) cry. I’ve been on the losing end of many such battles and it’s a miserable place to be.
To bypass uncooperative doctors and insurance companies, I personally use request-a-test.com to order my own labs. Request-a-test allows you to choose between LabCorp or Quest Diagnostics for the blood draw. Heads Up Health can electronically connect to Quest Diagnostics so my results will update automatically.
Step 2 – Scheduling the blood draw
I scheduled an appointment with Quest Diagnostics to have the blood draw.
Note: for extra nerd points, I brought my glucometer with me to the lab. I wanted to take a reading with my glucometer at the same time as the laboratory blood draw so I could see how accurate my glucometer was compared to results from a full-blown lab testing company with far more sophisticated technology for analyzing blood samples. Results are covered later in this post.
Step 3 – Assessing my test results
Within 24-hours, I received an e-mail notification from request-a-test that my test results were available. Since it had been many years since my last fasting insulin test, I was anxious to see the results:
- Fasting glucose: 84 mg/dL
- Fasting insulin: 4.8 µIU/mL
Note: The reading on my glucometer was 88 mg/dL (compared to 84 mg/dL from Quest), which was taken just moments before the blood draw from the lab. Overall, I’d say my trusty old glucometer held up pretty good!
Step 4 – Calculating my HOMA-IR score
With fasting insulin and fasting glucose readings in hand, I was now equipped with the data I needed to calculate my HOMA-IR score to assess my level of insulin resistance.
I used the HOMA-IR calculator located here. After entering my results into the HOMA calculator, my score was 1.0. I was pleased with this result and felt assured that both glucose AND insulin levels were in properly in check.
Step 5 – Tracking my results
Heads Up Health was designed to empower individuals to make informed, data-driven health decisions. Our product gives you the ability to easily track and manage your own lab test results, which can be a powerful tool on your own health journey.
I entered my results for fasting glucose, fasting insulin and HOMA-IR and saved this data in my Heads Up profile. I also uploaded a copy of the PDF from the lab so I have the source documents for future reference.
This post is a simple example that summarizes the topics covered thus far in the Low-carb Lab Testing series. The post demonostrates how anyone can get in the driver’s seat and order their own labs when the need arises.
I was able to order my own fasting glucose and fasting insulin tests without the need for doctor intervention. I was then able to calculate my HOMA-IR score and assess my results. Lastly, I used Heads Up Health to store my results so I have easy access to them for future reference. I can also test again in a year or two and easily compare my results to previous tests.
This is true patient empowerment and something everyone should have access to if they so desire.
Breast cancer occurs when the normal cells in the breast start growing rapidly and spreading locally. If left untreated, these cells can travel to other parts of the body and continue to grow. Besides skin cancer, breast cancer is the most common type of cancer and it is the second leading cause of cancer-related deaths in US women (lung cancer is the first). Preventing breast cancer is not possible in most cases, but thanks to a few simple breast cancer screening tests, we can detect breast cancer in its initial stages, when treatment is more successful.
How do we Screen for Breast Cancer?
You may hear about other ways to screen for breast cancer, but for average-risk women, screening mammography is the gold standard of care.
A mammogram is an X-ray image of the breast that allows us to detect cancer at early stages, often when it is still too small to notice by touch. Currently, this is the most widely used and accepted screening method. While the other imaging techniques below may offer additional information, they should only be reserved for special circumstances and not for general screening purposes.
Magnetic Resonance Imaging (MRI):
MRIs use magnetic waves instead of X-rays to image the breast tissue. MRI detects breast cancers better than the mammogram, but because of its tendency to also over-diagnose cancer in healthy breast tissue, it leads to unnecessary, more invasive testing in people who do not need it. For this reason, a mammogram is still the gold-standard screening tool.
Ultrasounds use real-time sound waves to visualize the breast tissue and are also not recommended for general screening. It can be useful as a follow-up to an abnormal mammogram, or in women with dense breast tissue.
Women should also be aware of their normal breast tissue. If they notice any changes that are unusual or concerning, they should discuss them with their doctor.
Evidence shows that women who have regular screening mammograms are less likely to die from breast cancer than those who do not.
When does the breast cancer screening Begin?
Recommendations can vary slightly depending on the source you read, so it is always a good idea to talk to your doctor about your risk factors and determine the best option for you.
As a general rule:
- Average-risk women should start screening at age 40. For most women, this means scheduling your first mammogram at this time.
- Some low-risk women may have the option to delay mammograms for several years until the age of 45 or 50.
- All women by age 50 should have had at least one mammogram, regardless of risk.
- Screenings should continue every 1-2 years until at least the age of 74.
If cost is an issue, the CDC has resources to provide low-cost woman’s health services including mammograms. Check out their website to see if you qualify.
What does my Test Result Mean?
An abnormal mammogram result does NOT mean you have breast cancer. In fact, most women who are recalled for additional testing after an abnormal mammogram are found they do not have cancer. No screening test is perfect, and the mammogram is no different.
In most of these cases, we perform a diagnostic mammogram where additional images are taken of the breasts focusing on the area(s) of concern.
“On average, 10% of women will be recalled from each screening examination for further testing, and only 5 of the 100 women recalled will have cancer.”
A normal mammogram result also does not guarantee that you are cancer-free. Studies estimate that mammograms can miss early cancers in up to 20% of cases.
That is a scary thought, but it sheds some light on why it is important to continue scheduling your mammogram every year even if yours have all been normal. Each subsequent mammogram decreases the likelihood of missing early cancer exponentially — The odds drop to 4% after the second mammogram, and are just 1% after the third.
If you have been putting off that mammogram this year, now is a good time to call and schedule it.

Let’s face it: if you’re concerned about your health, you’ve got to take matters into your own hands. Between battling your insurance company, working with an uncooperative doctor, and going up against outdated dietary advice that’s dying far too slow a death, if you want to attain and maintain optimal metabolic health, sometimes you have to get in the driver’s seat and order your own lab tests.
Doctors are intelligent, hardworking, and dedicated people, but they’re not infallible. Between seeing patients, dealing with burdensome paperwork, and overseeing the day-to-day operation of their offices, many of them have precious little time left for staying up-to-date on the latest research in their fields. And even if they’re keeping current with developments in their particular specialty, they might remain unaware of breakthroughs in other disciplines that could have important implications for their own—and for your health.
What this means is, if you’d like to run your labs more frequently than your doc is inclined to order them for you, or you want to get some lab tests your doctor isn’t familiar with, you have to go a different route.
In this post, we’ll show you how to run your own labs so you can obtain the information you need to feel in control of your health. We will also show you how Heads Up Health can help you manage all of your health data, including lab test results, in one single and secure location. You can learn more about the Heads Up Health service by clicking on the button below. Or, read on for more information on how you can take control of your health by running your own lab tests.
Reasons to Order Your Own Lab Tests
- Uncooperative doctors: If you request certain tests from your doctor because your own research has led you to believe they’d give you valuable information, don’t be surprised if the doc doesn’t share your enthusiasm. Even if you present them with an armload of studies from reputable scientific journals to support your case, your doctor still might not be keen on ordering anything and everything you request. For better or worse, lots of folks consult “Dr. Google” these days, and while there’s a world of helpful information regarding health and wellness to be found online, there’s also a lot that’s misleading, confusing, and just plain wrong. So you can’t blame your doctor for hesitating. While you’re the expert on your own body, he or she is the expert when it comes to medicine. So if your doctor is uncooperative, it’s not because they’re stubborn and enjoy giving you a hard time. More likely it’s that they’re simply not aware of the importance of some of the tests you might ask for. (Case in point: fasting insulin—the most important test doctors aren’t ordering.)
- You want to test more frequently than your insurance covers: When you make changes to your diet and lifestyle, good things start happening fast. For example, blood glucose, insulin, and blood pressure can decrease dramatically within just a few days of starting a low-carb diet. Other favorable changes take only a few weeks. But maybe your insurance covers a checkup and routine bloodwork only every six months, or once a year. You don’t want to wait that long. Seeing for sure that your triglycerides have come down or you’ve got much less inflammation could encourage you to stick with whatever plan you’re following. Nothing motivates more than results.
- Insurance doesn’t cover the tests you want: Insurance companies aren’t in the habit of paying for anything they don’t deem absolutely necessary. So if you’re looking for tests outside the mainstream—an advanced cholesterol panel, for example—you’re often on your own.
- You want a test that falls outside the conventional offerings: Food sensitivity tests, organic acid profiles, stool testing, and other tests that are well-known within the low-carb, ketogenic, and Paleo/ancestral health communities aren’t exactly household words. Many doctors wouldn’t even know how to order these for you. If you want this kind of cutting-edge testing—perhaps to get answers to longstanding health concerns that have not resolved after exhausting other options—you’ll need to find a private company that offers them.
So what’s a concerned patient to do?
Good news! There are now several options available for you to order your own lab tests—no referral required! You can order the tests you’d like, print out the requisition, and visit a lab to have your blood or urine sample collected. The results are sent directly to you (usually electronically, through an account you create with the testing company).
The companies that provide these services typically don’t accept payment by insurance, but they can provide you with a detailed receipt or medical CPT codes so you can file for reimbursement from your insurance company. (Be sure to check with your provider; not all insurance companies will reimburse for this.)
Don’t let an uncooperative doctor or a stingy insurance company be a roadblock to gathering data you feel is important for your health. Remember: Nobody cares about your health more than you do. But you can’t track things if you don’t have the data, and you won’t have the data without running lab tests.
Here are five companies providing direct-to-consumer lab tests:
- Request A Test (Wide range of tests available as packages or a la carte. Uses LabCorp and Quest Diagnostics for lab services; testing not available in all states. Certain restrictions apply on orders for customers under 18 years of age.)
- DirectLabs (Wide range of tests available as packages or a la carte. Uses Quest Diagnostics for lab services; not available in MD, NJ, NY & RI. Orders not accepted for customers under 18 years of age.)
- InsideTracker (Offers three different testing packages; fewer tests available than other services, no option for fasting insulin, thyroid hormones, or female sex hormones.)
- WellnessFX (Wide range of tests available as packages or a la carte.
- MyMedLab (Wide range of tests available as packages or a la carte. Uses Quest Diagnostics for lab services.)
Note: When you purchase lab tests from Request-a-Test, DirectLabs, InsideTracker or MyMedLab, they will direct you to Quest Diagnostics to have the blood drawn and analyzed. The good news is Quest Diagnostics is already integrated with Heads Up Health. This means you can connect Quest Diagnostics to your Heads Up profile and your lab test results will instantly synchronize. See this video for more information on connecting Quest Diagnostics to your Heads Up account or contact us if you need assistance.

This is the third installment in a series of articles exploring lab tests for people following low-carb diets, and how this way of eating requires a slightly different perspective for interpreting the results compared to results from people eating more carbohydrates.
In part 1, we covered tests for blood sugar (fasting glucose, hemoglobin A1c, and fructosamine). In part 2, we explored fasting insulin, the most important test most doctors aren’t ordering. Taken together, these explain why fasting glucose and hemoglobin A1c in the “normal” ranges don’t always mean someone’s in the clear with regard to insulin sensitivity and healthy glucoregulation. (Crash course: for many people, dangerously high insulin is the only thing keeping glucose levels in a healthy range.)
Throughout this series, we’re emphasizing that health cannot be determined by any single measurement in isolation. It’s a mosaic, made up of many individual parts that are best assessed as a whole. With this in mind, let’s dig a little deeper into the relationship between glucose and insulin. (more…)
