By now, the venture world is wary of blood testing startups offering health data from just a few drops of blood. However, Baze, a Swiss-based personal nutrition startup providing blood tests you can do in the convenience of your own home, collects just a smidgen of your sanguine fluid through an MIT manufactured device, which, according to the company, is in accordance with FDA regulations.

The idea is to find out (via your blood sample) which vitamins you’re missing out on and are keeping you from living your best life. That seems to resonate with folks who don’t want to go into the doctor’s office and separately head to their nearest lab for testing.

Most health professionals would agree it’s important to know if you are getting the right amount of nutrition — Vitamin D deficiency is a worldwide epidemic affecting calcium absorption, hormone regulation, energy levels and muscle weakness. An estimated 74% of the U.S. population does not get the required daily levels of Vitamin D.

“There are definitely widespread deficiencies across the population,” Baze CEO and founder Philipp Schulte tells TechCrunch. “[With the blood test] we see that we can actually close those gaps for the first time ever in the supplement industry.”

While we don’t know exactly how many people have tried out Baze just yet, Schulte says the company has seen 40% month-over-month new subscriber growth.

That has garnered the attention of supplement company Nature’s Way, which has partnered with the company and just added $6 million to the coffers to help Baze ramp up marketing efforts in the U.S.

I had the opportunity to try out the test myself. It’s pretty simple to do. You just open up a little pear-shaped device, pop it on your arm and then press it to engage and get it to start collecting your blood. After it’s done, plop it in the provided medical packaging and ship it off to a Baze-contracted lab.

I will say it is certainly more convenient to just pop on a little device myself — although it might be tricky if you’re at all squeamish, as you’ll see a little bubble where the blood is being sucked from your arm. For anyone who hesitates, it might be easier to just head to a lab and have another human do this for you.

The price is also nice, compared to going to a Quest Diagnostics or LabCorp, which can vary depending on which vitamins you need to test for individually. With Baze it’s just $100 a pop, plus any additional supplements you might want to buy via monthly subscription after you get your results. The first month of supplements is free with your kit.

Baze’s website will show your results within about 12 days (though Schulte tells TechCrunch the company is working on getting your results faster). It does so with a score and then displays a range of various vitamins tested.

I was told that, overall, I was getting the nutrients I require with a score of 74 out of 100. But I’m already pretty good at taking high-quality vitamins. The only thing that really stuck out was my zinc levels, which I was told was way off the charts high after running the test through twice. Though I suspect, as I am not displaying any symptoms of zinc poisoning, this was likely the result of not wiping off my zinc-based sunscreen well enough before the test began.

For those interested in conducting their own at-home test and not afraid to prick themselves in the arm with something that looks like you might have it on hand in the kitchen, you can do so by heading over to Baze and signing up.
