86710 Antibody; influenza virus

Name of the Procedure:

Antibody; influenza virus

• Common names: Flu antibodies test, Influenza antibody test
• Medical terms: Influenza virus antibody detection

Summary

This test measures the antibodies in your blood that your immune system has produced in response to an influenza virus infection or vaccination.

Purpose

The test helps diagnose an influenza virus infection or checks if you have developed immunity after receiving a flu vaccine. The goal is to confirm past exposure to the virus or verify that the body has responded to the flu vaccine effectively.

Indications

• Experiencing flu-like symptoms and needing confirmation of an influenza infection.
• Determining immunity status post-vaccination.
• Assessing immune response in individuals with weakened immune systems.

Preparation

• No special preparation is usually needed.
• Inform your healthcare provider about any medications or supplements you are taking.
• A simple blood test might be required beforehand to determine specific antibody levels.

Procedure Description

1. A healthcare professional will clean the area on your arm where the blood will be drawn.
2. A tourniquet is applied to your upper arm to fill veins with blood.
3. A needle is gently inserted into your vein, and blood is collected into a vial or syringe.
4. The sample is sent to a laboratory for analysis to detect the presence of influenza antibodies.

Duration

The procedure of drawing blood typically takes about 5-10 minutes.

Setting

The procedure is usually performed in a hospital, outpatient clinic, or medical laboratory.

Personnel

• Phlebotomist or nurse to draw the blood.
• Laboratory technician or pathologist to analyze the blood sample.

Risks and Complications

• Minor risks include slight pain or bruising at the needle site, dizziness, or fainting.
• Rare complications could include infection at the puncture site or excessive bleeding.

Benefits

• Confirms past influenza infection or successful vaccination.
• Helps guide treatment decisions for flu-like symptoms.
• Provides peace of mind regarding immune status.

Recovery

• Post-procedure care involves simply applying a small bandage over the needle site.
• Most people can resume normal activities immediately.
• Hydrate well and apply pressure if bruising occurs.

Alternatives

• Other diagnostic tests for influenza include PCR testing or rapid antigen tests.
• PCR tests are more accurate but take longer, while rapid antigen tests provide quicker results but may be less sensitive.
• Discuss with your healthcare provider which test is most appropriate for your situation.

Patient Experience

• You might feel a slight pinch or sting when the needle is inserted.
• Some discomfort might occur at the puncture site, but it should be minimal.
• Any pain or bruising can be managed with over-the-counter pain relief and cold packs.
