Epinephrine (Epi)


What is epinephrine?

Epinephrine, also known as adrenaline, is a hormone produced by the adrenal gland. It plays a key role in the body's "fight or flight" response, helping the body to respond to stress or danger.

What are the effects of epinephrine on the body?

Epinephrine has many effects on the body, including:

  • Increasing heart rate and blood pressure.
  • Dilating the bronchi in the lungs, making it easier to breathe.
  • Constricting blood vessels in the skin and mucous membranes, redirecting blood flow to the muscles and brain.
  • Suppressing the immune system and increasing blood sugar levels.

How is epinephrine measured in a laboratory setting?

Epinephrine can be measured through a blood test or a urine test. In a blood test, a healthcare provider will take a sample of the patient's blood and send it to a laboratory for analysis. In a urine test, the patient will collect a sample of their urine and bring it to a laboratory for analysis.

What is the normal range for epinephrine levels in the body?

The normal range for epinephrine levels in the body is not well established, as levels can vary widely depending on the individual and the specific circumstances.

What can cause abnormal epinephrine levels in the body?

Abnormal epinephrine levels can be caused by a variety of factors, including:

  • Medications such as decongestants or asthma inhalers.
  • Certain medical conditions such as pheochromocytoma (a rare tumor of the adrenal gland) or adrenal insufficiency.
  • Physical or emotional stress.

How is an abnormal epinephrine level treated?

Treatment for an abnormal epinephrine level will depend on the underlying cause. For example, if the abnormal level is caused by a medical condition such as pheochromocytoma, treatment may involve medications or surgery to remove the tumor. If the cause is a medication, the healthcare provider may adjust the dosage or switch to a different medication.

What other hormones or substances are commonly tested alongside epinephrine?

Other hormones or substances that may be tested alongside epinephrine include:

  • Cortisol, another hormone produced by the adrenal gland.
  • Norepinephrine, a hormone produced by the adrenal gland and the sympathetic nervous system.
  • Dopamine, a neurotransmitter involved in the regulation of movement, emotion, and motivation.
