What is cortisol?

Cortisol is the stress hormone that affects several systems in the body, including the:

The adrenal glands produce cortisol. Most human body cells have cortisol receptors, and the hormone can help in several ways, including:

  • reducing inflammation
  • regulating metabolism
  • assisting with memory formation
  • controlling blood pressure
  • developing the fetus during pregnancy
  • maintaining salt and water balance in the body
  • controlling blood sugar levels

All these functions make cortisol a vital part of maintaining overall health. If the body can no longer regulate cortisol levels, it can lead to several health disorders, such as Cushing’s syndrome and Addison’s disease. Without treatment, these conditions could cause life threatening complications.

The body requires certain cortisol levels during times of stress, such as:

  • in the event of an injury
  • during illness
  • during a surgical procedure

What are home cortisol tests? 

A cortisol test usually involves a blood test. However, some may require saliva and urine samples instead.

There are several home cortisol tests available to purchase over the counter or online. These allow a person to take a sample of blood, urine, or saliva before sending it off for analysis.

After taking a home cortisol test, people can usually receive their results within 2–5 days online or via a telephone call with a healthcare professional.

However, there are currently no studies investigating the reliability of these home cortisol tests. Therefore, people should follow up on their test results with a healthcare professional.

Why and when do people need them? 

A person should take a home cortisol test if they feel they may have a cortisol imbalance.

If cortisol levels are too high, a person may notice the following:

  • rapid weight gain in the face, chest, and abdomen
  • high blood pressure
  • osteoporosis
  • bruises and purple stretch marks
  • mood swings
  • muscle weakness
  • an increase in thirst and need to urinate

If cortisol levels are too low, a person may experience the following symptoms:

  • fatigue
  • loss of appetite
  • unintentional weight loss
  • muscle weakness
  • abdominal pain

Additionally, low cortisol levels may lead to:

A test can help individuals check their cortisol levels. If the test results show these levels are too high or too low, people should seek medical advice.

A cortisol imbalance may be a sign of an underlying condition, which can lead to serious complications without treatment.

If a person cannot carry out a home cortisol test, they should speak to a medical professional who can arrange a cortisol test at a healthcare facility.

What to look for in a home cortisol test

At a clinic or hospital setting, a medical professional will usually take a blood sample and analyze it for an individual’s cortisol levels.

Home cortisol tests involve a person taking a sample of blood, urine, or saliva. There are currently no studies investigating the accuracy of these results.

However, home cortisol tests may be faster and more convenient than making an appointment with a doctor to take a sample.

People may consider several factors when deciding to purchase a home cortisol test, including:

  • Sample type: Some tests require a blood sample, while others need a sample of urine or saliva. With this in mind, a person may wish to buy a product that uses a testing method they are comfortable providing.
  • Test analysis: A person may wish to purchase a product from a company that sends tests to Clinical Laboratory Improvement Amendments (CLIA)-certified labs for analysis. The Food and Drug Administration (FDA), Center for Medicaid Services, and the Centers for Disease Control and Prevention (CDC) regulate these labs to help ensure safety and accuracy.
  • Accuracy: Individuals may wish to speak to a pharmacist or other healthcare professional before purchasing to ensure the test is reliable and accurate.

LetsGetChecked – Cortisol Test

This cortisol test uses the finger prick method to draw blood for the sample.

Here are the steps to take and send off a blood sample:

  1. Individuals fill in their details on the collection box and activate their testing kit online at the LetsGetChecked website.
  2. People need to wash their hands with warm soapy water before using an alcohol swab to clean the finger that they will prick.
  3. Once the finger is completely dry, individuals pierce the skin using the lancet in the test kit. A person must wipe away the first drop of blood before squeezing some into the blood collection tube.
  4. After closing the tube, individuals must invert it 5–10 times before placing it in the included biohazard bag, which they then place in the box.

After following these steps, people can send the sample back to LetsGetChecked using the kit’s prepaid envelope. Test results usually come back within 2–5 days.

Healthlabs Cortisol, AM & PM Test

Healthlabs offers a cortisol test that tests a person’s cortisol levels twice — once in the morning and once in the evening.

This test uses a blood sample, which a person takes once in the morning and once in the afternoon. They must follow the instructions clearly to ensure they take suitable samples.

The manufacturer says that people should collect a morning sample between 7–9 a.m. and an evening sample between 3–5 p.m.

They then need to send off their sample for analysis. After testing is complete at a CLIA-certified lab, a person will receive their results, which usually takes between 1–2 days. SHOP NOW

When to speak with a doctor

A person should undergo a cortisol test if they believe they may have high or low cortisol levels.

They can do this at home or speak with a medical professional who can carry out the test for them.

People may also wish to seek medical help if they show signs of too much or too little cortisol. This could indicate a potentially serious underlying health issue.
