Antibody; rubella

CPT4 code

Name of the Procedure:

Antibody; rubella
(Common names: Rubella antibody test, Rubella IgG test, German measles antibody test)


The rubella antibody test is a blood test used to determine if an individual has immunity to rubella (German measles). This is typically assessed by measuring the presence of rubella-specific antibodies, indicating past infection or immunization.


  • Medical condition addressed: Assessing immunity against rubella.
  • Goals: To confirm whether a person has immunity, particularly important for pregnant women or women planning to become pregnant to avoid the risk of congenital rubella syndrome in newborns.


  • Symptoms or conditions: Women of childbearing age, especially those planning pregnancy or already pregnant, individuals suspected of current rubella infection.
  • Patient criteria: Pregnant women not previously tested for rubella immunity, healthcare workers, travelers, or unvaccinated individuals.


  • Pre-procedure instructions: No special preparations required; normal diet and medications can be maintained.
  • Diagnostic tests: None required beforehand.

Procedure Description

  1. Blood sample: A healthcare professional will draw a blood sample from a vein in your arm using a needle.
  2. Equipment: Sterile needle, syringe, and collection tube.
  3. Anesthesia: None required, though a local anesthetic cream may be used in rare cases to minimize discomfort.


The blood draw typically takes about 5 to 10 minutes.


The procedure is performed in a clinical setting such as a doctor's office, outpatient clinic, or laboratory.


  • Healthcare professionals: Typically carried out by a phlebotomist, nurse, or medical technician.

Risks and Complications

  • Common risks: Minor bruising or discomfort at the needle site.
  • Rare risks: Infection, excessive bleeding, fainting.


  • Expected benefits: Confirmation of immunity status, essential for preventing congenital rubella syndrome in newborns.
  • Timeline: Results are usually available within a few days.


  • Post-procedure care: Minimal, apply pressure to the puncture site to stop any bleeding.
  • Expected recovery: Immediate; normal activities can be resumed right after.


  • Other options: Rubella vaccination can be an alternative for non-immune individuals, though it is not recommended during pregnancy.

Patient Experience

  • During the procedure: Mild discomfort or a quick sting when the needle is inserted.
  • After the procedure: Minor soreness or bruising at the puncture site; usually no significant pain or side effects.

Pain management and comfort: Cold packs and over-the-counter pain relievers if necessary.
