Cortisol AM Blood (CORTAM)

Price: 15 د.ا

The Cortisol AM Blood Test (CORTAM) is a diagnostic tool used to measure the level of cortisol in the blood. Cortisol, a steroid hormone produced by the adrenal glands, plays a crucial role in various bodily functions including metabolism, immune response, and stress management. The “AM” in CORTAM indicates that the test is conducted in the morning, when cortisol levels are typically at their peak.

 

Normal Ranges

Cortisol levels vary throughout the day, peaking in the early morning and declining throughout the day. Here are the normal ranges for cortisol levels in the morning:

– Adult Males: 5-25 µg/dL (micrograms per deciliter)

– Adult Females: 5-25 µg/dL

– Children: 3-21 µg/dL (this range can vary slightly depending on age and laboratory standards)

 

Function in the Body

Cortisol is often referred to as the “stress hormone” because it is released in response to stress and low blood-glucose concentration. It has several key functions:

1. Metabolism Regulation: Cortisol helps regulate metabolism by influencing the way the body uses carbohydrates, fats, and proteins.
2. Inflammatory Response: It has potent anti-inflammatory properties, helping to control the body’s immune response.
3. Blood Sugar Levels: Cortisol increases blood sugar through gluconeogenesis, ensuring that the body has enough energy during periods of stress.
4. Blood Pressure: It assists in maintaining blood pressure and cardiovascular function.

 

Symptoms of Deficiency

Cortisol deficiency can lead to a condition known as Addison’s disease or adrenal insufficiency. Symptoms include:

– Chronic fatigue

– Muscle weakness

– Weight loss

– Low blood pressure

– Hyperpigmentation (darkening of the skin)

– Salt craving

– Hypoglycemia (low blood sugar)

– Nausea, diarrhea, or vomiting

– Irritability and depression

 

Symptoms of Overdose

Excess cortisol can lead to Cushing’s syndrome, characterized by the following symptoms:

– Rapid weight gain, especially around the abdomen and face

– A round, red face (moon face)

– High blood pressure

– Osteoporosis

– Skin changes, including bruising and purple stretch marks

– Muscle weakness

– Mood swings, anxiety, and depression

– High blood sugar levels (potentially leading to type 2 diabetes)

 

Diagnosis

Diagnosing cortisol-related conditions involves several steps:

1. CORTAM Blood Test: The primary test to measure cortisol levels.
2. 24-Hour Urinary Free Cortisol Test: Measures cortisol levels in urine collected over 24 hours.
3. Salivary Cortisol Test: Measures cortisol levels in saliva, usually collected late at night when levels should be low.
4. ACTH Stimulation Test: Evaluates adrenal gland function by measuring the response to adrenocorticotropic hormone (ACTH).
5. Dexamethasone Suppression Test: Assesses how cortisol levels respond to synthetic glucocorticoids.

 

More Information

Cortisol imbalances can significantly impact health, making accurate diagnosis and management essential. Lifestyle changes, medications, and in some cases, surgery, are potential treatments for cortisol-related disorders. Regular monitoring and consultations with healthcare providers are critical for managing these conditions.

 

Frequently Asked Questions

Q1: Why is the cortisol blood test done in the morning?

A: Cortisol levels are highest in the morning and lowest around midnight. Testing in the morning provides the most accurate assessment of baseline cortisol production.

Q2:What can affect cortisol test results?

A: Factors such as stress, illness, physical activity, and certain medications (e.g., corticosteroids, birth control pills) can influence cortisol levels.

 Q3: How should I prepare for a CORTAM test?

A: Generally, fasting is not required, but it’s essential to follow any specific instructions provided by your healthcare provider. Avoiding stress and physical exertion before the test can help obtain accurate results.

Q4: Can cortisol levels be managed naturally?

A: Yes, lifestyle changes such as a balanced diet, regular exercise, sufficient sleep, stress management techniques, and avoiding caffeine and alcohol can help maintain healthy cortisol levels.

Q5: How long does it take to get results from a CORTAM test?

A: Results typically take a few days to be processed and analyzed. Your healthcare provider will discuss the results and any necessary follow-up actions.

 

Understanding cortisol levels and their impact on health is crucial for diagnosing and managing various medical conditions. The Cortisol AM Blood Test is a valuable tool in assessing adrenal function and ensuring optimal health.
