Anti Centromere Antibodies

The Anti-Centromere Antibodies (ACA) Test is a blood test that detects antibodies directed against centromere proteins, which play an important role in cell division.

This test helps healthcare professionals investigate autoimmune conditions, particularly limited cutaneous systemic sclerosis, also known as CREST syndrome.

What Does This Test Check?

• Detects anti-centromere antibodies in the blood.

• Supports the investigation of systemic sclerosis.

• Helps assess suspected CREST syndrome.

• May assist in evaluating certain connective tissue disorders.

• Supports autoimmune disease assessment alongside other clinical investigations.

Sample Requirements

• Sample Type: Serum

• Required Quantity: 2–3 cc

• Department: Immunology / Serology

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

• Inform your healthcare provider about medications and existing medical conditions.

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

Important Information

A positive Anti-Centromere Antibody result may support the diagnosis of systemic sclerosis, but it does not confirm the condition on its own. Results should be interpreted alongside symptoms, physical examination, medical history, and other investigations.

Reporting Time: To be confirmed by the laboratory.

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