Cortizol is usually higher in the early hours of the day, so the morning analysis helps to improve the function of the above – school glands. Stress, sleep deprivation, and some drugs can affect the outcome
Blood cortisol analysis at 9: 00 a.m. is used most frequently to assess the function of the supersect glands. The reason is simple: Cortizol does not stand at the same level throughout the day, but follows a clear daily pace. It is usually higher in the early hours of the morning and then gradually decline during the day, reaching the lowest values about midnight.
For this reason, samples for the hormone are usually obtained between 8 and 9 o’clock in the morning. At that time the cortisol is near its natural peak, so the result provides a more useful view of whether the organism is producing the hormone properly.
Cortizol is not just a stress echo.
Cortizol is often known as the stress horn, but its role is much broader. It is produced by super-student glands and helps regulate blood sugar levels, blood pressure, inflammatory processes and the sleep cycle. So it’s the essential hormone for normal functioning of the organism.
Because of this important role, its measurement may help to diagnose certain serious hormonal disorders.
Why is it important at exactly 9?
Nine o’clock wasn’t chosen by accident. By this time, cortisol has usually reached the highest level or is still very close to it. This makes the test most valuable, especially when a doctor doubts the lower function of the overstress glands.
If the analysis is later in the day, the interpretation becomes more difficult because the values fall naturally. A seemingly low afternoon outcome may be quite normal at that time, while a morning value at the border may indicate that the production of the cortisol is not enough, it transmits Telegrafi.

What diseases can be valued with this analysis?
Doctors require measuring cortisol in the morning especially when they suspect diseases like Addison’s Disease i n Cushing syndrome.
Addiscon’s disease occurs when the overstress glands do not produce enough cortisol and often even aldosterone. This is a rare but serious situation. Signs may include intense fatigue, weight loss, low tension, muscle weakness, dizziness, increased appetite for salt food, and skin erosion.
On the other hand is the Cushing syndrome, which relates to protracted exposure to high levels of cortisol. Symptoms can include weight gain, especially in the stomach and face, purple vision, light bruises, increased blood sugar, high blood pressure, and mood changes.
A single adult or low result, however, is not enough for diagnosis. It is always interpreted along with symptoms, medical history, and, when necessary, additional tests.
What can affect the outcome?
Cortizol is very sensitive to external factors. In addition to sickness, it may affect its level:
- acute stress; acute stress;
- Fear of needles or taking blood;
- lack of sleep;
- Acute infections or diseases;
- heavy physical activity;
- child;
- Some drugs, especially cortichosteroids and contraceptive pills.
For this reason, the doctor always values the outcome in context rather than as an isolated number.
How can you prepare for analysis?
Proper preparation is so important that the outcome is as reliable as possible. The fast is often recommended for 8 to 12 hours before analysis, while water is usually permitted. You have to avoid intense physical activity the day before because I can temporarily increase the cortisol.
Also, try to get a good night’s sleep before the analysis because lack of sleep can affect the production of the hormone. It’s very important to tell your doctor or laboratory about all the drugs and supplements you get. Some of them may influence the outcome, but you should never stop therapy on your own without the doctor’s instructions.
How can you reduce stress on your test day?
Since stress can increase the cortisol, it is wise to move to the laboratory a little earlier so that you will not be hasty. During the wait, try slow, deep breathing. If you fear blood or feel very tense, inform your health staff. Sometimes it takes a few minutes to calm down before taking the sample to make the outcome more real.
In the end, it should be considered that a single test of cortisol is just part of the evaluation. It is of great value, but its full meaning depends on symptoms, medical history, and medical judgment. /Telegraphy/
