Overview
Prenatal testing consists of direct isolation of the virus, viral nucleic acid quantification or detection of antibodies against rubella in fetal blood via various invasive techniques, such as amniocentesis, fetal blood sampling, and chorionic villi sampling.[1][2][3][4][5] Postnatal testing consists of isolation of the virus from throat or urine cultures[6] and detection of serology (IgG or IgM antibodies against rubella).[1][7][8][9][10][11] Other laboratory findings in infants with congenital rubella syndrome include thrombocytopenia and elevated levels of PT, PTT, and bilirubin.[12]
Laboratory Findings
Prenatal Testing
Invasive Techniques
Several invasive techniques can be done during pregnancy, depending on the gestational age. These techniques include:[1][2][3][4][5]
| Technique | Timing/ Gestational age at which it is performed | Results | Complications |
|---|---|---|---|
| Amniocentesis | after 15 weeks |
|
|
| Fetal blood sampling | after 18-20 weeks | ||
| Chorionic villus sampling | after 11 weeks |
Post-natal Serologic Testing
Isolation of Virus
Rubella virus can be detected from nasal, throat, urine, and blood specimens from infants with CRS.[6]
Serological Testing
Several serological investigations can be done to confirm CRS. These include detection of IgM or IgG antibodies or IgG avidity. Several methods can be used, which include ELISA, hemagglutinin inhibition (HI) and immunofluorescent antibody assay (IFA).[1][7][8][9][10][11]
Other Laboratory Findings
Other laboratory findings in infants with CRS include:[12]
- Thrombocytopenia
- Elevated PT and PTT
- Elevated levels of bilirubin
