What is an Alpha-1 Antitrypsin Test (ATT)?

The Alpha-1 Antitrypsin Test (AAT) is a diagnostic blood test used to measure the levels of alpha-1 antitrypsin in a person's blood. Alpha-1 antitrypsin (AAT) is a protein produced in the liver and released into the bloodstream, where its primary function is to protect the lungs and other tissues from damage caused by enzymes such as neutrophil elastase. Neutrophil elastase is an enzyme produced by white blood cells and is involved in the breakdown of proteins in the body.

Low levels of alpha-1 antitrypsin can lead to a condition known as alpha-1 antitrypsin deficiency (AATD), which is a genetic disorder. AATD is characterized by an increased risk of developing lung and liver diseases. The lack of AAT in the lungs allows neutrophil elastase to damage lung tissues, leading to conditions like chronic obstructive pulmonary disease (COPD) and emphysema at an earlier age than usual. In the liver, the deficiency can cause liver disease, including cirrhosis.

The is crucial for identifying individuals with AATD so that they can receive appropriate medical management and interventions to slow down or manage the progression of associated lung and liver conditions. This test typically involves drawing a blood sample from a patient and then analyzing the serum or plasma to measure the concentration of alpha-1 antitrypsin.

Depending on the results, individuals with AATD may be advised on lifestyle modifications, medications, and, in some cases, supplemental alpha-1 antitrypsin therapy to manage their condition.

How Does It Work?

Sample Collection

A trained healthcare professional begins by collecting a blood sample from the patient, typically from a vein in the arm. The sample collection is crucial as it provides the specimen for subsequent analysis.

Blood Processing

The drawn blood sample undergoes meticulous processing, where it is centrifuged to separate the liquid component, either serum or plasma, from the cellular elements. This processed sample contains the proteins, including AAT, which will be examined in the test.

Laboratory Analysis

The isolated serum or plasma is subjected to laboratory analysis. This often involves employing enzyme-linked immunosorbent assay (ELISA) techniques to quantify the concentration of AAT within the sample.

Interpretation of Results

Following the analysis, the results are reported in precise measurements, usually milligrams per deciliter (mg/dL) or micromoles per liter (��mol/L). These values are then compared to established reference ranges.

Diagnostic Assessment

Trained healthcare providers interpret the results to ascertain the presence and degree of AAT deficiency. Deficiencies can range from mild to severe and affect lung and liver health.

When Would You Use This Test?

The Alpha-1 Antitrypsin Test is a valuable diagnostic tool healthcare practitioners use in various clinical scenarios. Here are some critical situations and medical specialties in which this test is particularly relevant:

  • Diagnosing Alpha-1 Antitrypsin Deficiency (AATD): Pulmonologists often use this test to confirm the presence of AATD in patients with unexplained lung conditions, such as early-onset emphysema and chronic obstructive pulmonary disease (COPD). AATD is a genetic disorder that predisposes individuals to lung diseases due to inadequate levels of alpha-1 antitrypsin.
  • Assessing Liver Function: Hepatologists may order the Alpha-1 Antitrypsin Test when evaluating patients with suspected liver disease, as AATD can lead to liver problems, including cirrhosis and liver failure.
  • Early Detection in Children: Pediatricians may recommend this test for children with a family history of AATD or unexplained respiratory or liver issues. Early diagnosis is crucial for managing the condition effectively.
  • Family Planning: Genetic counselors may suggest the Alpha-1 Antitrypsin Test for couples with a family history of AATD, helping them make informed decisions about family planning and genetic risk assessment.
  • Risk Assessment Before Surgery: Anesthesiologists and surgeons may consider this test before elective surgeries for patients with a history of AATD, as the deficiency can impact respiratory function and perioperative outcomes.
  • Public Health Initiatives: In some regions, public health programs advocate for widespread screening of high-risk populations, such as individuals with a family history of AATD or specific ethnic groups known to have a higher prevalence of the condition.
  • Evaluating Treatment Efficacy: Researchers and pharmaceutical companies involved in AATD-related studies and clinical trials use this test to assess the impact of experimental therapies and interventions.

What Do the Results Mean?

Interpreting the results of an Alpha-1 Antitrypsin Test is crucial for diagnosing and managing alpha-1 antitrypsin deficiency (AATD). The results are typically reported as the concentration of alpha-1 antitrypsin (AAT) in the patient's blood, often measured in milligrams per deciliter (mg/dL) or micromoles per liter (��mol/L). Here's what expected results may signify:

  • Normal Range (Typically 100-200 mg/dL): If the test results fall within the normal range, the patient has adequate levels of alpha-1 antitrypsin in their blood. This is reassuring, indicating no deficiency of this protective protein.
  • Mild AATD (60-80% of Normal Range): A result in this range may indicate mild alpha-1 antitrypsin deficiency. Individuals with mild deficiency may have a slightly increased risk of developing lung or liver disease later in life.
  • Moderate AATD (30-60% of Normal Range): Falling within this range suggests a moderate deficiency of alpha-1 antitrypsin. Patients with moderate deficiency have a higher risk of developing lung conditions like emphysema, particularly if they smoke or are exposed to other lung irritants.
  • Severe AATD (Less than 30% of Normal Range): A result indicating severe deficiency raises significant concerns. Individuals in this category have a substantially elevated risk of developing severe lung diseases, often at a younger age, and may also be at risk for liver problems.

It's important to note that the interpretation of results should be done in consultation with a healthcare provider who can consider the patient's medical history, family history, and overall health. Additionally, other factors, such as smoking or exposure to environmental toxins, can exacerbate the effects of AATD.

Research & Evidence

The Alpha-1 Antitrypsin Test is grounded in a history of scientific research and clinical evidence that spans several decades. 

The story begins with the discovery of alpha-1 antitrypsin (AAT) in the mid-20th century. Dr. Laurell and Dr. Eriksson, Swedish scientists, were the first to isolate and characterize this protein in 1963. They found that AAT protects lung tissues from damage caused by enzymes like neutrophil elastase.

Subsequent research led to the recognizing of alpha-1 antitrypsin deficiency (AATD) as a genetic disorder in which individuals inherit two faulty AAT genes, reducing functional AAT levels in the blood. AATD was linked to an increased risk of lung and liver diseases.

The Alpha-1 Antitrypsin Test has become a cornerstone in diagnosing AATD. Research studies have confirmed its accuracy in measuring AAT levels in blood samples, enabling clinicians to identify individuals with AATD.

Extensive clinical studies have demonstrated the link between AATD and the development of lung conditions, such as chronic obstructive pulmonary disease (COPD) and emphysema. Research has also shown that AATD can lead to liver diseases, including cirrhosis.

Clinical trials and observational studies have explored the efficacy of alpha-1 antitrypsin replacement therapy interventions in managing AATD. These therapies have been shown to slow the progression of lung disease in some individuals.

Advances in genetic research have led to a deeper understanding of the various genetic mutations associated with AATD, contributing to improved diagnostic accuracy and genetic counseling.
