Everything your body does, from breathing to keeping warm, requires energy. Energy is derived from your nutritional intake. Metabolism refers to the chemical processes that turn what you eat and drink into energy. Multiple tests are available to analyze your metabolism. Most are done in medical settings, but you can order some of them online and do them at home. At-home metabolism tests are one way to determine if your metabolism is working at its best. In this roundup, we’ll go over the pros and cons, as well as the two best options for at-home metabolism tests. What is a metabolism test and can you do one at home? Metabolism tests, or metabolic tests, are done to measure the rate at which you burn calories or use oxygen. Tests can use your breath, blood, or saliva to analyze hormones, chemical byproducts, and other metabolic markers. Some measure your oxygen intake and carbon dioxide output. What can at-home metabolism tests check? At-home metabolism tests measure hormones or other markers that affect metabolism. They can be a first step for determining whether your metabolism is functioning properly. These tests require you to give a saliva sample, blood sample, or both. Then, you send your samples to a laboratory to be processed. Hormones measured by at-home metabolism tests Cortisol. Cortisol is known as the stress hormone. It helps to regulate blood glucose, which is used as fuel by the body. Cortisol is known as the stress hormone. It helps to regulate blood glucose, which is used as fuel by the body.

They can also indicate testosterone deficiency (low T) in men. Testosterone is produced by people of all genders. Free testosterone levels can be useful for diagnosing metabolic conditions in women, such as polycystic ovary syndrome. They can also indicate testosterone deficiency (low T) in men. Thyroid-stimulating hormone (TSH). TSH controls thyroid hormone production. Thyroid hormones stimulate a wide range of the body’s metabolic activities. Your TSH level provides information about your basal metabolic rate. Types of metabolism tests Hormonal metabolism tests are the only type you can do at home. Other tests can provide more and different information based on a larger blood sample, but they require you to go to a lab or work with a doctor first. Your doctor can prescribe a metabolism test and perform it in a medical setting. They may do a blood draw at the hospital or recommend a laboratory where your blood will be drawn. If you wish to choose your own lab, look for one that is Clinical Laboratory Improvement Amendments (CLIA) certified . You may be able to order some metabolism tests that require a laboratory visit online, without a doctor’s prescription. Many fitness centers and medical spas also provide some types of metabolic testing onsite. At-home metabolism test At-home metabolism tests use blood samples, saliva samples, or both. People primarily use these tests to help with their weight and fitness goals. At-home kits typically measure hormones that affect metabolism rate. These include: cortisol

free testosterone

TSH They may also measure cholesterol and other significant markers that can affect your health. You can order at-home test kits online.

kidney function

liver function Your doctor may require you to fast before taking this test. Resting metabolic rate (RMR) test An RMR test analyzes the amount of oxygen you breathe in and the amount of carbon dioxide you breathe out. This test helps determine the number of calories your body burns while you’re resting, rather than in motion. It’s done while you’re sitting or reclining. To do this test, you will breathe into a tube connected to a computer. The computer will analyze the composition of your breath and produce a report on your oxygen consumption and carbon dioxide output. Aerobic capacity (VO₂ max) test VO₂ max is the maximum amount of oxygen that can be transported to working muscles per minute, during strenuous activity. The VO₂ max test measures the amount of carbon dioxide you exhale while exercising. It provides information about your oxygen intake and caloric burn while engaging in aerobic activity. Your doctor or coach may have you walk or run on a treadmill while breathing into a mask to do this test. It is often used to analyze athletic performance and potential in people who participate in competitive or extreme sports. Lactate threshold test The lactate threshold test is a series of blood tests that measures your lactate threshold. During athletic activity, your body uses oxygen to break down glucose, which it uses as energy. If there isn’t enough oxygen intake, lactate is produced instead. Your body converts lactate to energy without the aid of oxygen. Your lactate threshold is the point at which lactate starts to accumulate in your blood at a faster rate than the rate at which your body can eliminate it. Lactate threshold tests may be done while you undergo increasing levels of strenuous activity, such as running, cycling, or swimming. They’re usually used by endurance athletes and those who participate in competitive sports. Pros and cons of at-home metabolism tests At-home metabolism tests can be a valuable tool. However, they don’t take the place of a doctor’s input. Some pros and cons are: Pros You’re not required to go in to a medical office to give a sample.

These tests are most beneficial when combined with a physical examination and evaluation of your medical history. Faulty results can occur. These may be caused by many factors including human error, inaccurate testing, medications you take, or something you ate or drank prior to testing. How they work At-home metabolism tests use blood and saliva samples you take yourself and mail back to the company. These samples are analyzed in a lab to determine whether your hormones or other levels are high, low, or normal. The results indicate how your hormones or other markers may be affecting your metabolism and weight. They also may provide clues about your energy level and libido.
