CORTISOL BLOOD TEST

Cortisol is a hormone that affects nearly every organ and tissue in your body, often referred to as the "stress hormone" due to its role in stress response. 

Beyond stress, cortisol influences body fat by increasing appetite and promoting fat storage, especially around the abdomen. 

Elevated cortisol levels can stimulate fat and carbohydrate metabolism, leading to increased energy and appetite, which can cause weight gain. This hormone encourages abdominal fat storage, linked to higher health risks. Chronic stress and consistently high cortisol levels can therefore contribute to increased body fat and related health issues.

DOCTOR'S COMMENTS

Hi, I am Dr. Adam Staten and here's my view on this test as a GP and Clinical Director at One Day Tests.

DR. ADAM STATEN - GP VIEW AND RED FLAG SYMPTOMS

Cortisol, a hormone produced by the adrenal glands, plays a crucial role in regulating various bodily functions such as metabolism, immune response, and stress management. It helps maintain blood pressure, reduce inflammation, and control the sleep-wake cycle. The adrenal glands, located above the kidneys, release cortisol in response to signals from the pituitary gland and hypothalamus, forming the hypothalamic-pituitary-adrenal (HPA) axis.

Proper adrenal function is vital for overall health, as imbalances in cortisol levels can lead to conditions like Cushing's syndrome (excess cortisol) or Addison's disease (insufficient cortisol). Understanding cortisol and adrenal gland function is essential for diagnosing and managing stress-related and endocrine disorders.

Red flag symptoms for the Cortisol Blood Test

Even if your blood tests are normal, you should see a doctor if you have any of the symptoms below because they may be a sign of serious underlying illness. 

  • Progressive muscle weakness
  • Unexplained weight loss
  • Progressively severe symptoms of any kind

SPECIAL INSTRUCTIONS

Hi, I am Stefania Brown, I am the Laboratory Manager at One Day Tests and here are the lab's special requests for the Cortisol Blood Test.

SPECIAL INSTRUCTIONS

The time of day you measure cortisol is important as cortisol levels naturally fluctuate throughout the day.

They are typically highest in the early morning (around 6-8 AM) and gradually decline throughout the day, reaching their lowest point around midnight.

This diurnal variation means that cortisol measurements taken at different times can provide different information.

Clinic appointment - how to prepare for the Cortisol Blood Test

If you are coming into one of our clinics for the test, this is what you need to do before you arrive:

  • Read the instructions in the SPECIAL INSTRUCTIONS section
  • Drink plenty of water about an hour before the appointment.
  • Avoid coffee/tea/energy drinks. Water is good!
  • That’s it! We’ll do the rest.

Home test kit - how it works with the Cortisol Blood Test

Our blood test kits are simple and convenient.

The most important step in doing a blood test at home is to read the instructions very carefully. The process is very simple, but there are a few pitfalls you need to be aware of - you will save yourself a lot of time if you do it right the first time around!

  • Full printed instructions will arrive with your kit - please read them carefully.
  • Drink plenty before taking the sample and warm your hands up in the sink with warm water for a few minutes. This will make your blood flow much better.
  • Fill the tubes to the top line. We don’t need much blood; filling tubes to the top line is about 15 drops of blood.
  • Post the samples on the same day you take them, before midday, Monday to Thursday. If you post it any other time it might get to us late or be stuck at a sorting office over the weekend. You will then have to do it again.
  • Package the sample in the same box the kit came in. Otherwise, Royal Mail or DPD will reject it. The sample tubes go into a pouch, then into a cardboard box, and then into a return envelope. All of this is provided in the kit: please use it.

We look forward to receiving your sample in our lab!

FREQUENTLY ASKED QUESTIONS

Hi, I am Lana Nela, Lead Nurse, and here is what we are frequently asked about this test.

FREQUENTLY ASKED QUESTIONS

Here are some of the most frequently asked questions about the Cortisol Blood Test.

Why does the test have to be taken in the morning?

Like many other hormones, levels of cortisol fluctuate throughout the day in a cyclical pattern. Levels are highest in the morning, so this is when we recommend that you take the test. Taking it later in the day may give the false impression of low levels.

How does cortisol affect weight gain and belly fat?

This hormone can cause the body to store fat in the abdominal area, which is associated with higher health risks. Chronic stress and consistently elevated cortisol levels can, therefore, contribute to an increase in body fat and related health issues.

WHY HAVE THE TEST?

Hi, I am Nader Eldarf, I am a Biomedical Scientist in our laboratory and here is why it's important to take this test.

  1. WHY HAVE THE CORTISOL BLOOD TEST?

    Monitoring cortisol levels can provide insights into chronic stress and its impact on overall health.

    Elevated cortisol can lead to weight gain, high blood pressure, and other health issues.

    Understanding your cortisol levels allows you to work with healthcare professionals to manage stress and maintain a healthier lifestyle.

Hi, I am Sandeep Patel, I am the Laboratory Director at One Day Tests. Here are the symptoms that you may wish to address with this test.

  1. IS THE CORTISOL BLOOD TEST RIGHT FOR YOU?

    A cortisol blood test is essential for evaluating how your body responds to stress and identifying disorders related to the adrenal glands. Cortisol, produced by the adrenal glands, plays a key role in regulating metabolism, reducing inflammation, and controlling the body's sleep-wake cycle. Abnormal cortisol levels can indicate conditions such as Cushing's syndrome, Addison's disease, or adrenal insufficiency.
