These biowellness tests will give you insights into health and fitness at home

By this point, you’ve probably seen athletes of all styles walking around with a large black dot on the back of their arm. It’s a wearable – actually a sensor – called Levels that helps you understand how your body uses carbohydrates (more on that below).

There used to be special health tests only on the orders of a doctor – now you can send in blood, saliva and urine tests without ever putting on pants. This shift from outpatient to in-house testing is due to advances in sample collection. Whether you send in your samples or go to Quest Diagnostics, the science is basically the same, says Kamal Obbad, Co-Founder and CEO of Nebula Genomics.

The problem lies in the interpretation of the results. If your doctor orders a laboratory test, he will know your history and will review your data with this in mind. But when an algorithm spits out recommendations in an app (under the supervision of a doctor you’ve never met before) “be careful about considering this informational diagnosis”. Translation: Don’t make medical decisions based on a home test. “If possible, talk to an expert about your results.”

You can use these home tests to optimize your diet and fitness so you can feel better and function better.

1st stages: Best for optimizing your diet

Glucose – which comes from carbohydrates – is the fastest and most accessible form of fuel for your body. Go into a workout without enough in your system and you will likely buck. This bio-wearable uses a small sensor (attached to your upper arm) to monitor blood sugar levels 24/7 for two weeks. Manually log workouts and meals through the app and see live feedback on how they affect your blood sugar so you can adjust your habits to feel comfortable and do your best.

Spit in a tube, send your sample to the certified laboratory, and an independent board-certified doctor in your state will assess whether your level is normal.

5. Thorne: Best for fertility

Reproductive hormones run out of control can cause unexplained weight gain, sleep problems, mood swings, fatigue, and more – issues that affect people beyond those who are trying to get pregnant. Post your saliva swab and blood test and certified labs analyze hormone levels, thyroid function and stress responses to create a personalized health plan based on your results (think of tips like “focus on strength training in the morning” or “choose a Mediterranean diet”). Be careful with supplement recommendations; Since these are not regulated by the state, you should always discuss them with your doctor.
