How often should you have varicella and rubella titer done?

The recommended frequency for varicella and rubella titers depends on the individual's circumstances and risk factors, as well as the requirements set by healthcare providers or specific medical guidelines. Here's general information about when varicella and rubella titers may be done:

Varicella (chickenpox)

1. Before Vaccination: Individuals who have not been vaccinated against varicella may have a titer done to determine their immunity status. If the titer shows immunity, vaccination may not be necessary.

2. Post-Vaccination: A varicella titer may be recommended 4 to 8 weeks after the second dose of the varicella vaccine to confirm a successful immune response.

3. Healthcare Workers and Immunocompromised: For healthcare workers or individuals with compromised immune systems, regular varicella titers may be required to ensure ongoing immunity and potential need for booster doses.

4. International Travel: Some countries may require proof of varicella immunity for entry, and a titer can be used for this purpose.

Rubella (German Measles)

1. Preconception and Pregnancy: Women of reproductive age who are planning pregnancy or early in pregnancy may have a rubella titer done to check their immunity status. A titer showing immunity can help prevent rubella infection during pregnancy, which is crucial for avoiding birth defects.

2. Healthcare Workers and Lab Personnel: Regular rubella titers may be recommended for healthcare workers, lab personnel, and individuals working with pregnant women to ensure ongoing immunity.

3. International Travel: Similarly to varicella, some countries may require proof of rubella immunity for entry, and a titer can be used for this purpose.

It's important to consult with a healthcare provider or follow specific guidelines to determine the appropriate frequency and timing for varicella and rubella titers based on individual circumstances and risk factors.
