• Why is the Rubella PCR test important for pregnant women who have been exposed to the virus?

The test allows for the rapid diagnosis of an active infection, which is used to evaluate the potential risk of transmission to the fetus.

• Can the Rubella PCR test detect the virus in samples other than blood?

Yes, the virus can be detected in various tissues or body fluids, such as amniotic fluid, umbilical cord blood, and urine in critical cases.

About this service

A molecular test that uses polymerase chain reaction (PCR) technology to detect the genetic material (RNA) of the rubella virus in clinical samples. This test is more sensitive and specific than serological (antibody) tests for detecting active acute infection, especially in the early stages or in newborns suspected of having congenital infection.

Conditions and notices

Fasting is not required

Fasting is not required.

The type of sample is crucial: the sample is collected during the acute phase of the illness. It can be:

Nasopharyngeal swab (nose/throat).

Urine sample (especially for newborns).

Whole blood with an anticoagulant (EDTA).

Amniotic fluid (to check for fetal injury).

The sample must be transported to the laboratory quickly and under appropriate cooling conditions (2-8°C) to maintain the stability of the virus's ribonucleic acid (RNA).

Inform the laboratory of the suspected diagnosis and the date of onset of symptoms.

Frequently Asked Questions

Short answers to the FAQs published with this service.

• What is the main goal of the Rubella PCR test?

The test is used for the direct diagnosis of active rubella infection, particularly in the early stages before antibodies appear.

• How is the test used for newborns?

It is used to confirm or rule out Congenital Rubella in infants born to mothers who were infected or suspected of infection during pregnancy.

• What symptoms indicate a need for a Rubella PCR test?

A mild rash starting on the face and spreading, accompanied by low-grade fever and swollen lymph nodes behind the ears or neck.

• Is fasting required for the Rubella PCR test?
