Alpha 1-anti Trypsin Level

The Alpha-1 Antitrypsin (A1AT) Level Test is a blood test that measures the level of alpha-1 antitrypsin, a protein mainly produced by the liver. This protein helps protect lung tissues from damage caused by certain enzymes.

The test helps healthcare professionals investigate low alpha-1 antitrypsin levels, which may be associated with an inherited condition known as Alpha-1 Antitrypsin Deficiency.

What Does This Test Check?

• Measures alpha-1 antitrypsin protein levels in the blood.

• Helps investigate suspected Alpha-1 Antitrypsin Deficiency.

• Supports the evaluation of certain liver conditions.

• Helps assess possible genetic risk factors associated with lung and liver problems.

• May be recommended for patients with unexplained liver disease or early-onset lung disease.

Sample Requirements

• Sample Type: Clotted Blood or Serum

• Required Quantity: 3–5 cc

• Department: Clinical Chemistry / Immunology

Patient Preparation

• Fasting is generally not required unless instructed by your doctor or laboratory.

• Inform your healthcare provider about any existing medical conditions.

• Follow any specific sample collection instructions provided by the laboratory.

Important Information

Alpha-1 antitrypsin is an acute-phase protein, meaning its levels may increase during inflammation or infection. Results should be interpreted alongside clinical findings and other investigations. A normal or elevated level may not completely exclude an inherited deficiency; additional testing may be recommended by your doctor.

Reporting Time: To be confirmed by the laboratory.

Please confirm test availability and sample collection requirements with the laboratory before booking.
