86215 Deoxyribonuclease, antibody

Name of the Procedure:

Deoxyribonuclease, antibody (DNase Antibody Test)

Summary

The Deoxyribonuclease, antibody test, often referred to as the DNase Antibody Test, is a blood test that detects antibodies against the enzyme deoxyribonuclease (DNase). This test helps in diagnosing and monitoring autoimmune diseases, especially systemic lupus erythematosus (SLE).

Purpose

The primary purpose of this test is to identify the presence of DNase antibodies in the blood, which can indicate autoimmune activity. It is mainly used in the diagnosis and monitoring of systemic lupus erythematosus (SLE), a chronic autoimmune condition that affects various parts of the body.

Indications

• Persistent unexplained inflammation and pain.
• Symptoms such as fatigue, joint pain, and skin rashes.
• Suspected cases of systemic lupus erythematosus (SLE) or other autoimmune diseases.
• Monitoring known cases of SLE to gauge the effectiveness of treatment.

Preparation

• No specific preparation is required for this blood test.
• Patients should inform their healthcare provider of all medications and supplements they are taking, as certain drugs can affect test results.

Procedure Description

1. Blood Sample Collection:

   • A healthcare provider will clean the injection site, typically on the arm.
   • A tourniquet is applied above the site to make veins more visible.
   • A needle is inserted into a vein to draw blood into a vial or syringe.

2. Sample Analysis:

   • The blood sample is sent to a laboratory.
   • In the lab, the sample undergoes testing to detect the presence of DNase antibodies using specific assays.

Duration

The blood draw procedure typically takes around 5-10 minutes. The analysis in the lab may take several days, depending on the facility.

Setting

This procedure is usually performed in a healthcare provider's office, laboratory, or clinic.

Personnel

• Phlebotomist or nurse for blood draw.
• Laboratory technicians for analysis.

Risks and Complications

• Common risks include slight pain or bruising at the puncture site.
• Rare risks include infection or excessive bleeding, which are usually manageable.

Benefits

• Accurate diagnosis and monitoring of autoimmune diseases, especially SLE.
• Helps in tailoring and adjusting treatment plans for better disease management.

Recovery

• No recovery time needed for the blood draw itself.
• Patients can resume normal activities immediately following the procedure.

Alternatives

• Alternative autoimmune tests like Anti-Nuclear Antibody (ANA) test, Anti-double stranded DNA (Anti-dsDNA), and complete blood count (CBC).
• Each test has specific pros and cons; the DNase Antibody Test is especially useful for diagnosing and managing SLE.

Patient Experience

• The patient will experience a quick needle stick during the blood draw.
• Mild discomfort or bruising at the site may be felt but is temporary.
• Patients are advised to stay hydrated and keep the puncture site clean following the procedure.
