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.

Success Stories

Suzanne Young


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.
