86765 Antibody; rubeola

Name of the Procedure:

Antibody Test for Rubeola; Measles Antibody Test

Summary

The Antibody Test for Rubeola is a blood test used to determine if an individual has immunity to the measles virus, either from previous infection or vaccination.

Purpose

This test identifies whether a person has antibodies against the measles virus, which can confirm immunity to the disease. It helps diagnose current or past infection and assesses vaccination efficacy.

Indications

• Suspected measles infection.
• Confirmation of immunity status, particularly in outbreak settings or before travel.
• Pregnant women or individuals with compromised immune systems who need to confirm immunity to the virus.
• Healthcare or school staff as part of immunization compliance.

Preparation

• No special preparation is required, but informing the healthcare provider about any current medications or health conditions is advisable.
• Fasting is not typically necessary.

Procedure Description

1. A healthcare provider will clean the injection site, usually the inner arm.
2. A needle is inserted into a vein to draw a blood sample.
3. The blood sample is sent to a lab where it is tested for the presence of rubeola antibodies (IgG and IgM).
4. The test results take a few days to be processed.

Duration

The blood draw itself takes approximately 5-10 minutes. Lab results can take from a few days to a week.

Setting

The blood draw is typically performed in a hospital, outpatient clinic, or a diagnostic laboratory.

Personnel

• Phlebotomist or nurse to draw the blood.
• Laboratory technician or medical technologist to analyze the blood sample.
• Doctor or healthcare provider to interpret the results.

Risks and Complications

• Common risks include slight pain or bruising at the injection site.
• Rare risks include infection or excessive bleeding.
• Any complications are usually minor and manageable.

Benefits

• Confirms immunity to measles, providing peace of mind.
• Aids in the diagnosis of current measles infection for timely treatment.
• Helps prevent the spread of measles in communities by confirming individuals' immune status.

Recovery

• Minimal recovery needed; patients can resume normal activities immediately.
• Keep the injection site clean and monitor for signs of infection or excessive bruising.

Alternatives

• Measles IgM test specifically for diagnosing acute infection.
• Measles polymerase chain reaction (PCR) test for detecting viral RNA.
• Immunization history review, though less definitive than an antibody test.

Patient Experience

• Patients may feel a brief sting or pinch during the blood draw.
• Discomfort is usually minimal and temporary, with no lasting pain.
• Light bruising or soreness at the site might be experienced but typically resolves in a few days.

Pain management and comfort measures:

• Applying a cold pack to the site if there is discomfort or swelling.
• Over-the-counter pain relief if necessary.
