Dopamine
Dopamine
The dopamine test is used to measure the amount of dopamine in the blood sample.
Dopamine serves as a neurotransmitter that is crucial for the brain's reward and pleasure mechanisms. It is produced within in the brain and acts as a chemical messenger, aiding in the transmission of signals between nerve cells within the brain and throughout the body.
Getting this test done is recommended for aiding the diagnosis of certain mental health disorders, Parkinson's disease and rare adrenal tumours such as paragangliomas pheochromocytomas.
Symptoms of rare adrenal tumours
Headaches
Sweating
Rapid heart rate (palpitations)
Trouble breathing
Panic attack
High blood pressure
Stomach pain
Weight loss
Pale skin
Constipation
Blurry vision
Increased thirst
Frequent urination
What is a Dopamine test used for?
This test may be useful
To help diagnose or monitor conditions associated with abnormal dopamine levels
To monitor individuals who are undergoing treatment for a neurological or psychiatric disorder that is associated with dopamine imbalances
Preparation for the test
Refrain from consuming tea, coffee, bananas, citrus fruits, vanilla, walnuts, fava beans, avocados, cocoa, licorice, vanilla, and chocolate for a period of 2 to 3 days prior to the test, as these items can impact the accuracy of the test results. Ensure your healthcare provider is aware of what prescription drugs, over-the-counter medicines, or dietary supplements you are taking.
Interpretation of the test results
The normal range of dopamine is 0 to 30 picograms per millilitre (pg/mL). However, normal value ranges can differ slightly between laboratories as a result of variations in measurements.
What do abnormal results indicate
· Elevated dopamine levels may be caused by conditions such as Parkinson's disease, certain types of adrenal tumours such as pheochromocytomas, etc.
· Decreased dopamine levels may be caused by conditions like schizophrenia, depression, etc.
FAQs
How is the sample collected for the dopamine test?
A blood sample is collected from a vein in your arm using a small needle. Usually, this procedure does not take more than 5 minutes.
Are there any risks associated with the dopamine test?
No, there are no associated risks with the dopamine test. It is a simple blood test that carries minimal risks, such as experiencing a slight sting or bruise at the needle insertion site. Typically, these discomforts subside within a short period of time, ranging from a few minutes to a couple of hours. In rare cases, there is a possibility of infection at the needle insertion site.
How long should I wait for the dopamine test results?
The dopamine test result is usually available within 3-8 days after the sample collection. However, this duration may vary depending on the diagnostic clinic.
Can medications interfere with the accuracy of the test results?
Yes, certain medications such as antiemetic drugs (used to treat nausea and vomiting) and antipsychotic drugs can have an impact on dopamine levels. To ensure accurate results, it is important to inform the healthcare provider about all the medications you are currently taking prior to the test.
Why is dopamine known as the “feel-good hormone”?
Dopamine is often referred to as the "feel-good" hormone because it is responsible for providing a sense of pleasure and motivation. Engaging in pleasurable activities prompts the brain to release large amounts of dopamine, resulting in a heightened feeling of well-being and a desire for more. This explains the addictive nature of junk food and sugar, as they stimulate the release of dopamine in the brain, creating a sensation of euphoria and a craving to repeat that experience.
