WHAT RESULTS WILL I RECEIVE?

With this test, you can establish your body’s baseline values for basic health markers like cholesterol (total, triglycerides, HDL, LDL and total cholesterol/HDL ratio), glucose and hemoglobin A1c. Additionally, you will receive data on performance biomarkers such as Vitamin D, Creatinine, Testosterone and many more. The Fitnescity Method X gives you a comprehensive snapshot of your body’s overall fitness.

As with every Fitnescity test, your results are more than just numbers. Your results come with advanced insights to give you answers that may help improve values that are low, high, or out-of-range.

Will also be given the opportunity to add a physician consultation at no additional cost. 



SHOULDN’T I GET MY BLOOD TESTS FROM MY PHYSICIAN?

While blood tests may come with a periodic medical check-up, they are often administered when you have a medical problem and need a more intensive evaluation for a disease. Doctors are often unwilling to order the tests unless you are sick.

At Fitnescity, we believe that prevention in essential (more than 80% of the most common diseases are largely preventable with simple lifestyle changes). We believe that wellness starts with understanding and that everyone should be empowered to take control over their wellness. As a result, everyone can (and should) gain a basic understanding of blood testing.

Your blood tests can help you optimize for wellness and performance. You should consider tracking your results too.

WILL I BE ABLE TO UNDERSTAND MY RESULTS?

Like much of the medical space, blood testing can feel highly professionalized and difficult to understand for many people. However, Fitnescity helps you make the most out of your blood analysis using beautifully-designed, easy-to-understand reports and recommendations.

DOES THE FITNESCITY METHOD X COME WITH A CONSULTATION?

While your reports will give you all the information and recommendations you need to start making the most out of your tests, you will also be given the opportunity to speak with a board-certified physician if you wish (at no additional cost). You will receive instructions on how to schedule a call with the physician as soon as you receive your results.

IS THE FITNESCITY METHOD X (BLOOD ANALYSIS) COVERED BY INSURANCE?

Fitnescity tests are not covered by insurance. By purchasing this blood analysis, you will not be able to submit any claim, bill or other request for reimbursement to any insurer, third party payer or Government health program.

HOW SOON WILL I RECEIVE MY RESULTS?

You will receive your results two weeks from the date you mail your sample.



WHAT BIOMARKERS WILL I BE TESTED FOR?

+ Total Cholesterol

Total Cholesterol is a combination of three types of cholesterol: HDL, LDL, and part of triglycerides. High cholesterol may put you at risk for heart disease or stroke. A low cholesterol measurement can indicate other health conditions. It is possible for your total cholesterol to be high when your other cholesterol results are in healthy ranges. In this case, we recommend focusing on your triglycerides (if available), LDL, and HDL cholesterol results.

+ HDL Cholesterol

High Density Lipoprotein (HDL) cholesterol is commonly called "good" cholesterol. Unlike other cholesterol levels, the HDL cholesterol test result is best if it is high. Elevated HDL cholesterol is associated with decreased risk of heart disease. A low level of HDL cholesterol can be associated with increased risk for heart disease. Genetic factors or conditions including liver disease, malnutrition, or hyperthyroidism may decrease HDL cholesterol levels. Smoking and drinking alcohol may also decrease your HDL cholesterol level.

+ LDL Cholesterol

Low Density Lipoprotein (LDL) cholesterol is considered "bad" cholesterol. Elevated LDL cholesterol is associated with an increased risk of heart disease. LDL cholesterol often increases with a diet high in cholesterol and saturated fats. For many people, their LDL cholesterol is based on heredity. Lifestyle choices including diet and many medications are effective in lowering the LDL cholesterol level.

+ Cholesterol / HDL Ratio

Total cholesterol/HDL cholesterol ratio is a calculation obtained by dividing the total cholesterol level by the HDL cholesterol level and is another indicator of heart disease risk. A ratio of less than 5.0 is associated with a lower risk of heart disease. A ratio of less than 3.5 is highly desirable.

+ Triglycerides

Triglycerides are fats composed of fatty acids and glycerol. They are moved through the bloodstream by combining with proteins to form particles called lipoproteins. Triglycerides pass from the liver to other parts of the body that need lipoproteins for energy. Triglycerides then return to the liver where they are removed from the body. The level of triglycerides in your blood tells how well your body processes the fat in your diet. Accurate results require fasting for nine to twelve hours (no food or drink except water and medication) prior to testing.

+ Glucose (blood sugar)

Glucose (“blood sugar”) is the chief source of energy for all cells in the body. Glucose levels are regulated by hormones produced by your pancreas, including insulin. A glucose level outside the optimal range could be a sign that the body is not correctly producing or using insulin. These conditions are hypoglycemia (low blood sugar), prediabetes (elevated blood sugar), and diabetes (high blood sugar). For the most accurate result you should fast (not eat or drink anything but water) for at least 8 hours before your screening. If you were not fasting at the time of your screening, you should interpret your result against an optimal range of less than 140 mg/dL.

+ Hemoglobin A1C

Good fasting glucose levels can be misleading. Hemoglobin A1c measures the average amount of blood sugar (glucose) level for the past two to three months. The blood level of glucose is tightly controlled by hormones, especially insulin produced by the pancreas. Consistently, high blood glucose is typically observed in individuals with uncontrolled diabetes or undiagnosed diabetes. In people with diabetes, insulin is either less effective or not produced in sufficient quantity thus making it harder to manage the amount of sugar passing through the blood.

+ HS-CRP

Highly sensitive C-reactive protein (hsCRP) is made by the liver in response to infection, tissue injury or inflammation. Even low values, previously regarded as normal, have been shown to be a risk factor for atherosclerosis (fatty deposits lining the walls of blood vessels). Results of this test can help predict your risk of developing atherosclerotic heart disease. Buildup of these fatty deposits can cause chest pain, called angina, and eventually lead to a heart attack. Your risk increases with increasing levels of CRP.

+ Vitamin D

Vitamin D is a compound required by the body for the growth and maintenance of bones and teeth. In addition to this role, vitamin D is known to be involved with muscle function and protein synthesis. It has also been linked to muscle fibre size, neuromuscular performance, androgen status and immunity. Supplementation can improve health, speed, power, and strength in athletes. Athletes are regularly found to be deficient in vitamin D, especially during the winter months.

+ Testosterone

Testosterone is the primary male sex steroid hormone. Its release is regulated by the hypothalamus and the pituitary gland and is produced in the testes for males and ovaries for women. Testosterones effects on the body are considered anabolic (muscle building) and androgenic (developing and maintaining the male reproductive system). In mainly male athletes, testosterone is important for mediating the body’s adaptations to training and building muscles. Increase in testosterone levels occurs in response to exercise training sessions especially resistance exercise. Additionally, exercise training increases resting concentration of testosterone.

+ Creatinine

Creatinine is a metabolic waste product that is formed when creatine is broken down during metabolism. Elite athletes in several sports have relatively high creatinine levels due to a higher muscle mass. Levels can be increased when muscle is broken down from high volume and intense training and competitions. Therefore, it is a good indicator for muscle mass.

+ Estimated Glomerular Filtration Rate (eGFR)

eGFR is a measure of kidney function and provides a measure of the rate that kidneys are able to filter blood. The rate is based on the level of creatinine in the blood. eGFR results should be monitored regularly to ensure that the kidneys are functioning properly. Athletes may have a higher eGFR due to muscle mass and muscle metabolism. eGFR rates are temporarily decreased in the day following exercise however it usually returns to baseline in healthy athletes without 24 hours of the event.

+ Thyroid Stimulating Hormone (TSH)

TSH is a stimulatory hormone that stimulates the thyroid gland to secrete thyroid hormones (T3 & T4) that regulate metabolism and growth. Since the primary role of thyroid hormone is to regulate metabolic rate, improper function of the thyroid gland could lead to significant decreases in athletic performance. Hyperthyroidism has said to increase liver glycogen depletion, which could pose a threat to endurance athletes. In addition, over-secretion of thyroid hormones can even have a catabolic effect on skeletal muscle tissue. In the cases of low thyroid function, concentrations of growth hormone (GH) may be reduced. Disruptions in growth hormone production and release may blunt expected adaptations to training, subsequently impairing performance. If reductions in thyroid function are observed across a training cycle, it may indicate the need to taper training volume and intensity in order to allow your body to adapt optimally to your training stimulus.

+ Alanine Transaminase (ALT)

ALT is an enzyme in the liver that serves as a marker of liver function. There is some evidence that suggests that athletes tend to have elevated levels of ALT. ALT is a good indicator of overall health as optimal liver function is important to your metabolic capacity for exercise.

+ Aspartate Transaminase (AST)

AST is an enzyme found primarily in the liver that serves as a marker of liver function. It is located in the heart, skeletal muscles, spleen, lungs, and brain. In the body, AST plays a role in amino acid metabolism. It was found that some athletes have elevated levels of AST. AST is a good indicator of overall health as optimal liver function is important to your metabolic capacity for exercise.

+ Gamma-Glutamyltransferase (GGT)

GGT is produced in the highest concentration within bile ducts in the liver. It can be used as an indicator of liver disease and may rise with alcohol consumption and certain medications.
