About Cortisol
Cortisol is a stress hormone that is released when we are exposed to physical or mental stress. Cortisol is produced in the adrenal glands and helps you perform better physically and mentally in situations that the body perceives as acute stress. In the distant past, stress was a natural reaction to protect yourself from predators, whereas nowadays stress takes on a different form. Today, our stress comes from a modern setting, such as stress about paying the bills.
 
The stress we experience in today’s society often becomes chronic stress. This means high levels of cortisol building up in the body for long periods of time. This causes high levels of cortisol which is harmful and dangerous to the body, resulting in high blood pressure and high blood sugar which can cause type-2 diabetes.
 
However, too little cortisol in the body is not good either. If the cortisol levels become really low, the urine excretes large amounts of sodium, which can lead to life-threatening conditions. 
 
It is important to know if you are at a risk of being affected by any of these conditions. By taking GetTested’s Cortisol test, you can get an indication of your cortisol levels and take adequate measures to prevent cortisol disorders. 
The function of cortisol
Cortisol has a variety of functions in our body. In acute stressful situations, cortisol secretion helps you perform better, both physically and mentally. Cortisol is also important for the movement of the intestines and controls the body’s metabolism of sugar, fat and protein. With its anti-inflammatory effect, cortisol counteracts the function of the immune system, which makes us more susceptible to infections.
Your cortisol level is not always related to your stress level. Physical activity also increases cortisol secretion in the body, but unlike secretion during stress, cortisol instead reduces inflammation that occurs on the muscles. In the medical world, cortisol is best known for its anti-inflammatory and muscle-degrading effects in the treatment of inflammatory diseases, and this is then treated by adding cortisone.
Cortisol also controls the immune system and reduces swelling in allergies and insect bites. Therefore, Cortisol is a vital hormone for our wellbeing. 
Cortisol fluctuations 
Cortisol levels should be at the highest in the morning and lowest at night. The metabolism of fats, sugars and proteins is all controlled by the cortisol.  The amount of cortisol itself depends on what you do and how much stress you put on yourself. Stress can raise the cortisol levels, as well as being injured, having fever, infections or too high adrenaline. 
Symptoms of high cortisol:
In the long run, however, high levels are harmful to the body and with high levels of cortisol for a long time, fat burning decreases and impairs insulin sensitivity, which in the long run can lead to obesity and type-2 diabetes.

Fatigue
Low libido
Weight gain
Difficulty sleeping
High blood pressure
Poor immune function

Symptoms of low cortisol:
Low levels of cortisol can lead to menstrual disorders, muscle weakness and general mental illness, as well as cortisol inhibiting inflammation. In more rare and extreme cases, low cortisol can lead to adrenal insufficiency (also known as Addison’s disease). In such cases, the body does not make enough hormones. Diseases like Addison’s disease can cause life-threatening conditions and usually need to be medicated, but “Milder” conditions still cause a huge stress on the body and mind and should not be left untreated.
The most common symptoms of low cortisol are: 

Menstrual disorders
Fatigue
Muscle weakness
Low blood pressure
Loss of appetite
Nausea

Cortisol blood test vs cortisol saliva test
GetTested’s Cortisol Test measures your cortisol levels from your saliva instead of blood, making it a lot more convenient to use. For example, people with naturally cold hands may experience difficulty acquiring blood from pricking their finger, which makes a blood test not ideal. It is also more comfortable for people who are sensitive to blood and needles. 
Testing cortisol throughout the day
GetTested’s Cortisol Test measures bioavailable and free cortisol at seven points throughout the day, combining the first morning values into one, resulting in five reported values. Cortisol is released in response to physical or mental stress, enhancing physical and mental performance under short-term stress. However, consistently high cortisol levels can be harmful, while low levels can also pose health problems. This test is especially useful for those experiencing chronic stress, fatigue, or other stress-related symptoms.
For a comprehensive hormonal assessment, DHEA—another hormone affected by stress—is often measured alongside cortisol. Our DHEA Saliva Test can provide additional insights into your stress response and hormonal balance.

What is HbA1c?
HbA1c, also known as glycated hemoglobin, is a vital indicator to understand your average blood sugar level over the past three months. Unlike regular blood sugar tests, which provide only a snapshot, HbA1c offers a more comprehensive view of how your blood sugar has fluctuated over time. This is especially important as the lifespan of a red blood cell is approximately four months.
Why choose GetTested's HbA1C test?
HbA1c, or glycated hemoglobin, reflects average blood sugar levels over the past three months. Unlike regular blood sugar tests that show a single point in time, HbA1c provides a broader picture of glucose control. This is particularly relevant as red blood cells have a lifespan of approximately four months.
This HbA1c test specifically measures the amount of glycated hemoglobin in the blood. A result below 6% is considered normal, while levels above 6% may indicate diabetes. Unlike glucose and ketone urine tests, which provide a different type of health information, this test offers insight into long-term blood sugar control.
For a more comprehensive analysis
GetTested also offers a laboratory-based Diabetes Test HbA1C, providing a precise measurement of HbA1C levels for a deeper insight into long-term blood sugar control. Additionally, a rapid Diabetes test is available to measure glucose and ketones.
Quick and reliable testing
This HbA1C blood test offers a simple and effective way to monitor blood sugar levels. It provides valuable information for assessing diabetes risk and supporting proactive health management.

The DNA Cardiovascular Health test from GetTested provides a comprehensive insight into your cardiovascular health. By analyzing specific genes related to heart health, such as heart rate, heart rate variability, recovery after exertion, salt sensitivity, ApoB, TMAO, homocysteine, and LDL particle size, this test can offer valuable insights into your genetic predisposition for various heart-related conditions.
Lab Report and Recommendations
Once your results are ready, you will receive a detailed lab report from GetTested explaining your genetic insights and their significance for your cardiovascular health. The report also includes personalized recommendations to optimize your health based on your genetic results.
Sample and Integrity
The DNA and the original sample material are destroyed after analysis, and there is no personal connection to the sample other than your unique test ID to which your test results are linked. The information is completely anonymized, and the lab has no knowledge of whom it belongs to. We do not share or sell the results to any third party. You also have the option to delete your test results after reviewing them.
