You want your spark back.

Think of this as a broad check in on your body’s everyday chemistry. It measures blood sugar, minerals that help keep fluids balanced, and signs of how your liver and kidneys are working. It can help you and your clinician decide what deserves a closer look.

Vitamin D helps your body absorb calcium and supports bones, muscles, and immune function. This blood test checks the main form used to assess your vitamin D level, so you can discuss whether food, sun exposure, or supplements are meeting your needs.

TSH is the message your brain sends to your thyroid, the small gland that helps set your body’s pace. This blood test checks how strong that message is. It can be a starting point when you’re feeling unusually tired, cold, or unlike yourself; thyroid hormone tests may help fill in the picture.

CRP is a protein your liver makes when there is inflammation. This blood test can flag that something needs attention, but it cannot tell you where the inflammation is coming from. Your symptoms, recent illness, and health history help give the number meaning.

A sed rate, also called ESR, checks how quickly red blood cells settle in a tube. Faster settling can be a clue that inflammation is present. It helps guide the next questions, rather than identifying one particular illness.

A complete blood count looks at the cells doing the daily work in your blood: red cells carrying oxygen, white cells supporting your defenses, and platelets helping you clot. It can help investigate things like fatigue or anemia. This version counts white cells together, without separating all their different types.

Lipase is an enzyme your pancreas makes to help break down fat. This blood test checks for changes that may help investigate a pancreas problem, especially when there is abdominal pain. It is a targeted test, rather than a score for how well you digest every meal.

Amylase helps break down starches in foods like bread and potatoes. Your pancreas and salivary glands make it. This blood test can help investigate a problem involving those organs when symptoms point in that direction; other tests may be needed to understand the result.

Your immune system makes antibodies to recognize what it needs to respond to. An ANA test looks for antibodies that react with parts of your own cells. A positive screen may lead the lab to check their amount and pattern. It can help explore an autoimmune question, but a positive result alone does not mean you have an autoimmune disease.

This blood test checks cholesterol and triglycerides, fats that travel in your blood. It helps build a picture of heart and metabolic health alongside blood pressure, family history, food, and movement. The pattern matters more than treating one number as your whole health story.

This panel puts your thyroid’s instructions and output in the same conversation. TSH is the signal asking your thyroid to work; free T4 and free T3 are available thyroid hormones. Looking at them together can help make sense of changes in energy or temperature tolerance. Thyroid antibodies are a separate test.

A1c gives a longer view of blood sugar, roughly the past two to three months, instead of a single moment. It can help you understand blood sugar patterns and whether your current approach is helping. Conditions that affect red blood cells can change the result, so it belongs alongside the rest of your health picture.

Insulin is the hormone that helps move sugar from your blood into your cells for energy. This test measures how much is in your blood at collection. Read alongside blood sugar and whether you have eaten, it can help explore how your body is managing fuel.

Homocysteine is a substance your body makes as it processes protein. B vitamins help your body recycle it. A higher result can prompt a closer look at B12 and folate, kidney function, and other factors; it does not point to one cause or one supplement on its own.

B12 and folate, also called vitamin B9, help make healthy blood cells and support everyday cell function. This blood test checks both. If levels are low or borderline, the next question is why: what you eat, how well you absorb it, and medicines can all matter.

Magnesium helps your nerves, muscles, and many everyday body processes work. This test measures the magnesium circulating in your blood. It can flag an imbalance, but a normal result does not tell us everything about your body’s magnesium stores. The Fitness Edit includes a different test that measures it inside red blood cells.
