Our Story

When’s the last time when you had a patient or client and wondered what your next steps were going to be with them?

Maybe you had an idea of what direction you were going to go, or maybe you didn’t, but you knew that lab testing was likely going to be involved in making your decision.

But which tests should you run? Do you look for nutrient deficiencies, infections, autoimmunity, hormones, toxins, something else?

Each of those tests cost hundreds of dollars each. And you know that your client probably needs more than one.

But what if your patient said they could only afford one test, which single test do you choose, knowing that you might be missing out on critical information?

And what if you choose a test, they invest their hard earned money in it, and three weeks later the results come back without the results you were hoping for?

Now you’re stuck. You either have to guess what to do next, or convince your patient that they need to spend more money on testing.

Everyone’s been there. It stinks.

The reality is, it is more complicated to practice now than ever before. New lab tests are released all the time, and the list of things we’re supposed to look for in a patient or client seems to grow longer every year. We have more information to sift through, more decisions to make, and more things to consider than ever before.

However, the most important decision you make with a patient is still the same as it’s always been – the first decision. It’s the one you make during the first appointment and tells them where you’re going with their case. It can make or break their first impression of you, and either have them buy in to your plan for them, or push you and your ideas away.

Wouldn’t it be nice to knock it out of the park right off the bat?

What if instead of asking them to pay thousands of dollars in functional lab testing, blindly hoping to find something wrong with them, you could run a single, inexpensive blood test that provided enough accurate information that you were practically handed three months guidance for your patient, including what tests to run, what supplements to give, and what interventions to do.

Imagine this single blood test providing you with dozens of quantifiable pieces of information to clearly and accurately track their progress, motivate them to stick with your plan, and provide you with guidance for next steps in their case.

Does this sound too good to be true? We almost didn’t believe how great this software was once we first started to use it. It almost seemed too good to be true to us, as well. In fact, we struggled with exactly the same problems you struggle with as a practitioner, which is why we created this software in the first place. But then when we saw just how powerful it was and it solved so many problems for us, we had to share it with other practitioners just like you.

But all this and more is now consistently possible with the Blood Chemistry Calculator, a lab test analysis software program that will absolutely revolutionize your business.

By the way, have you ever tried any of the other software programs on the market?

We have.

In fact, we’ve tried all of them. And honestly, comparing any of them to the Blood Chemistry Calculator is like comparing dial-up internet to blazing fast, fiber-optics.

For example:
  • We use evidence-based reference ranges for each and every lab marker. (Most of the time, they can’t tell you where they got their reference range from.)
  • We make predictions using machine learning algorithms based on tens of thousands of lab tests. (They try to teach you “patterns” in the data that have little to no scientific basis to them.)
  • We’re publishing papers using the findings of our technology. (They haven’t published anything.)

Now, some practitioners don’t mind. They can still sleep at night giving their patients arbitrary, non-evidence based information.

But we couldn’t. And if you don’t want to either, you’re in the right spot.

Our team has had a collective dream to crack the code of blood chemistry analysis for over a decade. We were determined to find a newer and better way of utilizing blood chemistry testing instead of simply relying old technology and information, or flashy new and expensive functional medicine testing. Our combination of expertise in software engineering, conventional medicine, functional medicine, research, and biochemistry was exactly the combination that was needed to deliver you this incredible tool, the Blood Chemistry Calculator, that will truly revolutionize the way that you practice.

We have spent years poring over scientific research to bring you evidence-based reference ranges and have combined that with machine learning technology, utilizing tens of thousands of lab tests done on healthy individuals. The result?

The most intelligent, science-based blood chemistry software program on the market.

And not only that, it just keeps getting smarter. That’s right – the more data we enter, the better the software gets.

Our clients love how convenient the Blood Chemistry Calculator is. All you need is a simple, easily obtained and inexpensive blood test that people can do almost anywhere, upload it into our system, and then in just a couple of minutes you’ll have an in-depth and personalized report containing everything you need to take your patient or client to the next level of care.

Blood Chemistry Calculator users rave about the confidence they have knowing that they’re making clinical decisions based on predictions coming from tens of thousands of lab tests and evidence-based reference ranges.

The Blood Calculator is offered either as a one-time report or as a membership subscription service, but right now, we have a gift for you. We are so confident that you will love the Blood Calculator that, for a limited time we are offering you a free sample report.

We can’t wait to hear how much you learn about your state of health.

Discover Your Biological Age
with Our Free Report

Using data from tens of thousands of people, we trained a machine learning model that produces your predicted age based on how old your blood test results make you look. If you already have an existing blood test with most of the required markers, enter them into our system for free, and our model will explain your predicted age using a waterfall chart. This chart will tell you how each of your results contributed to your predicted age, which is a great place to start investigating how a blood test reflects your health. You can then unlock the full report at any time.

Frequently Asked Questions

What is the Blood Chemistry Calculator?

In a nutshell, The Blood Chemistry Calculator is a tool to maximise the value of basic blood chemistry. Using a machine learning algorithm called XGBoost together with blood chemistry data from 76,000 people, we can make predictions (forecast) the results of tests that either you haven’t done or that are unavailable outside a research setting. For example, if your haemoglobin is low, we can predict the likelihood of that being due to a copper, zinc, B12 or folate deficiency without you directly testing any of these nutrients! We can also forecast infections and inflammation, xenobiotic and heavy metal toxicity, hormones like testosterone, estrogen and thyroid, and metabolic health indicators like fatty liver and GlycoMark.

The Blood Chemistry Calculator also can condense your blood test down to a single scientifically validated marker called the 5-Year Wellness Score that can be tracked over time. We can also predict your age based on your blood markers, which you can then compare to your true chronological age.

If that wasn’t enough, we also have evidence and health outcome-based reference ranges including a bibliography.

Who is the Blood Chemistry Calculator for?
The Blood Chemistry Calculator will appeal to anyone looking for direction when it comes for testing. A basic blood chemistry is always the first place to start, and The Blood Chemistry Calculator is a powerful navigational device that can help you decide where to go next.
How does the forecast work?

The forecasts are based on data from 76,000 patients. Each prediction has around 90 percent sensitivity and specificity as verified by testing 25% of the data that was withheld from the initial training of the algorithm.

See the full list of things we can forecast, together with the sensitivity and specificity.

Do I have to order a blood test through you?
No. You can upload whatever file you have and we’ll take of the data entry. Your blood test should have most of the required markers (see next question).
What if my blood panel is missing some of the markers?

The Blood Chemistry Calculator handles missing data nicely. However, the accuracy of the output will be compromised to a degree that will depend on the missing input marker and the given forecast. For example, eosinophils seem to be highly predictive of a lot of problems. Therefore, we wouldn't recommend running the report without a complete blood count (CBC) with differential.

If you just have a lipid panel and you want to see where you fall within our evidence-based references, then great! Your test is fine for that, but don’t pay too much attention to the forecast.

How does the monthly membership work?

The monthly membership brings down the cost of each report from $50 to $25. This option makes the most financial sense for people who run many blood chemistries on a regular basis (such as practitioners). The membership includes monthly “Ask Us Anything” webinars. You can cancel the membership at any time with one click.

What are the monthly webinars about?

You decide! We can talk about how the Blood Chemistry Calculator works and how to use it. We can answer your personal questions as long as you don’t mind receiving the answer in a group setting so that everyone can learn. Bryan, Megan and Tommy would also like to teach some biochemistry and physiology if the interest is there.

What happens when I order a blood test through you?

Once you provide us with the details of the person getting blood drawn, we will email the address provided with a PDF requisition form that you can take directly to Quest Diagnostics. No need to make an appointment; you can just walk in. Once your results are ready, we’ll email you a link to your Blood Chemistry Calculator report.

If I order a blood test through you, will I get a copy of the results from Quest?


The Blood Chemistry Calculator found a problem I don’t understand, what do I do?

Consider the monthly subscription and webinars. Otherwise, email us and we’ll connect you with a practitioner.

Can I download a PDF containing my report?

The problem with PDF reports is that as the software improves, there’s no way to update the PDF you downloaded. Because we are constantly updating and improving the Blood Chemistry Calculator, a PDF report could quickly become outdated. We may make these available in the future, but for now you can hit control-P and print a PDF from your computer.

Can I see a sample report? Your algorithm got it wrong.

This question usually goes something like, “You predicted low folate but I measured that in blood and it was high. Your algorithm is wrong.” The algorithm could indeed be wrong, but before making that decision, please watch this video.

I have a question not covered here.

You guys are AWESOME!!!! So smart! THANK YOU, THANK YOU. I'm a practitioner living on an island in the Indian Ocean where functional blood testing is mission impossible!! (It's easier to export an animal than a pee sample with an overnight carrier). We do however have multiple Blood Chem Labs. This is going to be an amazing game changer for my practice!

Health Enthusiast

The Blood Chemistry Calculator forecast a 76% chance of elevated blood levels of lead, and at first, I thought, "no way!" However, I was an interior/exterior painter for a few years in my late 20s, so the forecast was plausible. I recently had a blood metals panel done with Quicksilver, and the lead on the blood panel was in the 98th percentile. I'd be happy to share more of my results, but I thought you might like to know how accurate your calculator is.
