About the test

The Fitness Profile – Basic Test is a test panel designed to help you understand your fitness readiness and overall health. It measures 60+ markers across overall health, metabolic function, hydration, and vitamin D status—core areas that influence how your body functions day to day and responds to physical activity.

It includes a comprehensive metabolic panel (CMP), complete blood count (CBC), cholesterol (lipid) panel, cortisol, glucose, electrolytes, serum osmolality, and vitamin D. Together, these markers provide insight into general health, heart health, metabolic readiness, hydration and electrolyte balance, and vitamin D levels that support bone, muscle, and immune health. Understanding these results can help identify potential contributors to low energy, inconsistent performance, dehydration, or challenges maintaining a regular fitness routine.

Additional to the 45+ biomarkers outlined above and detailed in the What’s tested section, this offering includes a biometric screening (physical measurements); and a health risk assessment survey, which helps provide a personalized Health Quotient Score. This score can be used to help you better understand and track your individual health and fitness goals over time. This test is well suited for establishing a baseline before starting a new workout program, checking in on your health as part of a routine fitness plan, or gaining clarity on how your body is functioning today. You’ll have the ability to discuss your results with an independent healthcare provider at no additional cost. They can help interpret your results in the context of your health history, activity level, and goals. We also encourage you to share your results with your regular physician.

This Fitness Profile – Basic Test contains tests and test panels within many key areas important to fitness and performance. In addition to providing the metrics, the results report will provide insights into why some of the standard metrics in base panels such as our CMP may be particularly relevant to athletes and any individuals looking to optimize fitness and performance.

Core health and metabolic readiness

The comprehensive metabolic panel (CMP) helps assess overall health, detect early signs of disease, and monitor chronic conditions. It measures 14 components: blood sugar (glucose), calcium, total protein, liver enzymes, bilirubin, blood urea nitrogen, creatinine, albumin, carbon dioxide, and key electrolytes. Abnormal CMP test results may indicate various health conditions, such as developing or active liver or kidney disease, hypertension, or diabetes and may result in additional tests being run on your existing sample, at no extra cost to you. Several metrics within your CMP including BUN and creatinine are liver and muscle waste products, so abnormal levels may indicate recovery strain.

This CBC test measures and evaluates the components of your blood cells, including red blood cells (RBCs), white blood cells (WBCs), and platelets. Red blood cells carry oxygen throughout your body. Abnormal levels can help identify conditions such as anemia, malnutrition, leukemia, and others. White blood cells are an important part of your immune system, and abnormal levels may mean your body is fighting an infection. Platelets help your blood clot normally. The CBC provides detailed measurements on the count, number, size, and other health-related factors relevant to red and white blood cells.

This lipid panel (or lipid profile) blood test measures your cholesterol and triglycerides levels to assess your risk for cardiovascular diseases. The lipid profile test works by measuring total cholesterol, triglycerides, HDL, LDL, cholesterol/HDL ratio, and non-HDL. Regular lipid panel testing plays a key role in maintaining both general and cardiovascular health.

As part of the CMP, your blood glucose is measured. This is the primary sugar found in your bloodstream. The sugar mainly comes from the food you eat and supplies energy to all cells in the body. High glucose levels may increase the risk of diabetes and associated disorders, such as heart disease.

At the time of your appointment, physical measurements such as your height, weight, waist size, and blood pressure are taken to provide you with additional health-related information.

Along with the biometric screening we provide you a health risk assessment, which is a brief survey that will capture family health history and current health and wellness behaviors. Combined with your diagnostic test results, these metrics will provide you with a personalized Health Quotient Score. The Health Quotient Score, developed by Quest, is a numerical representation of your health on a scale from 1 to 100. This score is unique to you and factors in select lab test results, a health risk assessment, and biometric screening. The higher your score, the better your health. You can use this number as your baseline, then develop a plan to improve your health and track your progress over time.

As a result of the health risk assessment, biometric screening and other results, you will receive risk scoring (each rated high, medium, or low) for 12 risk areas as well as a score for your metabolic syndrome risk.

Stress response

Cortisol is a hormone produced and released by the adrenal gland in response to stress. It regulates the metabolism of energy sources such as carbohydrates, lipids, and proteins in the body, as well as blood glucose levels and immune responses. The body's cortisol levels fluctuate throughout the day, peaking in the morning after waking and decreasing until midnight when they are lowest. Cortisol's main function during exercise is to keep blood glucose levels stable. Furthermore, during activity, cortisol levels rise, which helps the body power through exercise and training. However, cortisol also has a catabolic effect since it stimulates tissue breakdown and hinders protein production.

Hydration and electrolyte balance

Serum osmolality is a blood test to help individuals engaged in particularly high intensity training monitor the body's water balance. Osmolality is a measure of how concentrated a fluid is. In other words, it is a measure of the concentration of all chemical particles found in the fluid (serum) portion of blood. Low blood levels may indicate overhydration, while high levels may indicate dehydration.

As part of your CMP, calcium is measured. Calcium is one of the most abundant minerals in the human body and plays a key role in multiple bodily functions. Most of the calcium in your body is stored in your bones, with only 1% circulating in your bloodstream. Calcium is required for strong bones and teeth and proper nerve, muscle, and heart function.

As part of your CMP, sodium is measured. Sodium is a vital mineral in the body. It is carefully regulated by the kidneys and plays an important role in the body's water balance. Sodium is an electrolyte, which means it is a mineral with an electrical charge. Electrolytes affect how much water is in your body and how your muscles work. During exercise, sodium is the major electrolyte lost through sweat and the most important one to replace after exercise. Because sodium is essential for muscle and nerve function and hydration, it is critical to monitor and manage sodium levels in the body. Out-of-range levels may decrease muscle power and motor control during performance or cause muscle cramping.

As part of your CMP, potassium is measured. Potassium is an electrolyte that is also one of the body's most important minerals. It helps to regulate water balance, blood pressure, and heart rate. Potassium is also necessary for muscle contraction and nerve function. Monitoring and regulating potassium levels in the body is critically important, as potassium is essential to muscle and nerve function and hydration. Out-of-range levels may decrease muscle power and motor control during performance or lead to muscle cramping.

As part of your CMP, chloride is measured. Chloride is an electrolyte that helps to balance fluids inside and outside of your body's cells. Chloride plays an essential role in metabolism and is instrumental in maintaining proper blood volume, blood pressure, hydration fluid balance, muscle response, and acid/base balance. Blood chloride can be elevated when the body loses excessive amounts of sodium- chloride in the body through high rates of fluid loss. If the body is inadequately hydrated, the athlete may not be able to perform optimally.

Nutritional status and oxygen delivery (performance fuel)

This test measures the amount of 25-hydroxyvitamin D in your bloodstream, an indicator for the level of vitamin D in your body. Vitamin D is involved in regulating calcium and phosphorus, which are essential nutrients to promote bone strength and cellular health. Vitamin D can also help the immune system fight infections and is known to be involved in muscle function and protein production. Your body produces vitamin D after exposure to sunlight or from consuming certain foods and supplements.

FAQs

How does muscle affect eGFR?

Athletes may have eGFR outside of the range of normal values due to large amounts of muscle mass and muscle metabolism. In this situation, the effect is unlikely to be kidney dysfunction, but rather a larger demand on the kidneys because of high metabolic output. eGFR results can be monitored to ensure the kidneys are functioning appropriately to filter waste products from the blood.

What does it mean if my white blood cell count is out-of-range?

A low white blood cell count, also called leukopenia, may mean your body cannot fight off infection, and an excessive white blood cell count (leukocytosis) may indicate an infection or inflammation. Additionally, white blood cells are a component of the immune system and are classified into subtypes called neutrophils, monocytes, lymphocytes, eosinophils, and basophils. If the neutrophil count is high, this may be indicative of an acute infection, stress, muscle damage, rheumatoid arthritis, or other inflammatory disorders.

If the neutrophil count is low, it may be the result of a bacterial infection or medical condition. A consistently low neutrophil count, in the absence of disease, may be a sign of overtraining.

Monocytes can be elevated because of an infection, inflammation, allergic reaction, or asthma. During exercise, the number of monocytes in circulation increases. However, the number of monocytes in circulation normally returns to resting levels when exercise stops. Athletes, especially endurance and female athletes, may normally have lower monocyte counts than the range of normal results (called the reference range). This is often considered an adaptation to training.

An elevated lymphocyte count may mean an infection or other immune challenge. If the lymphocyte count is low, it may be the result of a medical condition. A low lymphocyte count may also occur from undernutrition, stress, use of corticosteroids (such as prednisone), or high exercise volumes.

If the eosinophil count is high, it could be the result of an infection, allergic reaction, eczema, or asthma. Certain medical conditions such as autoimmune diseases, hay fever, or leukemia are also associated with elevated eosinophil counts. If the eosinophil count is low, it may be the result of high levels of cortisol in the body or alcohol intoxication.

When the number of basophils, like eosinophils, climbs too high, they can contribute to allergies and other inflammatory reactions in the body. A low basophil count may indicate that the athlete is unlikely to be experiencing an allergic response and this is generally not a cause for concern.

I thought triglycerides were harmful, so why do they matter for athletic performance?

In medicine, triglycerides are used to monitor for conditions like diabetes or coronary artery disease. However, triglycerides can provide an important fuel during exercise. Triglycerides are a type of fat found in the blood. When you eat, your body converts any calories it doesn't need to use right away into triglycerides. The triglycerides are then stored in your fat cells. Later, when your body needs energy, hormones release the triglycerides into your blood so they can be used for fuel. This process is known as lipolysis.

People who exercise frequently tend to have lower levels of triglycerides in their blood because their bodies use more triglycerides for energy during exercise. Distance runners and other endurance athletes usually have the lowest levels of triglycerides because they use the most energy during exercise. Triglycerides are an important source of energy for athletes, helping them to maintain their performance during exercise.

Does hypothyroidism or hyperthyroidism affect athletic performance?

The primary role of thyroid hormones is to regulate metabolic rate, and improper function of the thyroid gland could lead to significant decreases in athletic performance.

If thyroid stimulating hormones, or TSH, is high, the thyroid gland is likely not producing enough thyroid hormones or working as it should. Underactive thyroid function can affect energy levels, growth, mood, and performance. Because of fatigue, hypothyroidism can make it difficult to exercise, and your capacity to train as an athlete is significantly reduced.

When the TSH level is low, it means that the thyroid gland is overactive and producing high amounts of thyroid hormones. An overactive thyroid may make maintaining muscle mass difficult. The oversecretion of thyroid hormones can have a catabolic effect on skeletal muscle tissue.

Importantly, athletes can maintain healthy thyroid hormone levels and avoid these complications with proper diagnosis and treatment.

What is the relationship between potassium and sodium?

The electrolytes potassium and sodium work in tandem to help maintain fluid balance and blood volume, nerve and muscle growth, heart function, and pH balance in the body. Your cells use potassium alongside sodium, and both are essential for cell function. There is a mutual trade-off between sodium and potassium to maintain balance within the body. An ion exchange occurs when sodium or potassium enters a cell. When sodium enters the cell, potassium leaves, and when potassium enters the cell, sodium leaves.

Aren't iron deficiency and iron deficiency anemia the same?

No, there is a difference between the terms, though they sometimes seem to be used interchangeably. Anemia is caused by insufficient levels of hemoglobin, whereas a lack of iron causes iron deficiency.

It's possible to have an iron deficiency while maintaining a normal hemoglobin level. However, a person with iron deficiency anemia has neither sufficient levels of hemoglobin nor iron. It's important to note that anemia can also be caused by issues other than iron imbalance, such as blood loss, inflammation, and certain health conditions.

What next steps should I take if I have an abnormal result?

You should share your results with a healthcare provider who can review your medical history and lab tests and together you can make a plan going forward that is right for you.

Can I use my FSA or HSA funds to purchase tests at questhealth.com?
