What is Aiat blood test?

This test measures the amount of alpha-1 antitrypsin (AAT) in the blood. AAT is a protein that is made in the liver. It helps protect your lungs from damage and diseases, such as emphysema and chronic obstructive pulmonary disease (COPD).

What does alpha-1 antitrypsin QN test for?

Alpha-1 antitrypsin (AAT) testing is used to help diagnose alpha-1 antitrypsin deficiency as the cause of early onset emphysema or chronic obstructive pulmonary disease (COPD) when a person does not have obvious risk factors such as smoking or exposure to lung irritants such as dust and fumes.

What are the symptoms of antitrypsin deficiency?

Individuals with AAT deficiency have a wide variety of symptoms which may include:

Shortness of breath.
Excessive cough with phlegm/sputum production.
Wheezing.
Decrease in exercise capacity and a persistent low energy state or tiredness.
Chest pain that increases when breathing in.

What does a positive a1a mean?

This is a type of blood test. It helps find out if you have a genetic disorder called alpha-1 antitrypsin deficiency. This disorder is linked to abnormally low levels or a lack of alpha-1 antitrypsin (AAT) protein in the blood. The disorder can cause liver and lung diseases.

Do I need to fast for alpha-1 antitrypsin?

An alpha-1 antitrypsin blood test is integral in defining the cause of early-onset emphysema and liver dysfunction. Preparation: Fasting for 10-12 hours required. Test Results: 1-3 days. May take longer based on weather, holiday or lab delays.

What does it mean if your alpha-1 antitrypsin is low?

The low level of AAT means that lungs are not protected, and the liver is injured by the build-up of the protein there. Alpha-1 can cause lung problems in adults and liver problems in both adults and children. Some of these conditions can be life-threatening.

Is alpha-1 a terminal illness?

Outlook / Prognosis Many people with Alpha-1, especially those who do not smoke, do not develop serious complications. They have a normal life expectancy. Other people may develop more serious conditions as a result of the disorder.

What does low AAT mean in a blood test?

A low level of AAT in blood indicates that the person tested may have alpha-1 antitrypsin deficiency. The lower the level of AAT, the greater the risk of developing emphysema and other disorders related to AAT deficiency.

What are the different types of AAT tests?

Three types of AAT tests are commonly available. One or more of these may be used to evaluate an individual: Alpha-1 antitrypsin measures the level of the protein AAT in blood. Alpha-1 antitrypsin phenotype testing evaluates the amount and type of AAT being produced and compares it to normal patterns.

What does it mean when AAT is high?

AAT is an acute phase reactant. This means that it will be elevated in acute and chronic inflammatory conditions, infections, and with some cancers. Increased levels of AAT may also be seen with oral contraceptive use, pregnancy, and stress.
