Description

Qualitative determination of IgG antibodies to the rubella virus in human serum.

Test Methodology

Chemiluminescent Immunoassay

Specimen Types

Whole blood and serum

Sample Volume / Collection Container

• 5 mL of whole blood collected in a red-top tube or serum separator tube (SST).
• 2 mL of serum collected in a sterile container.

Collection and Storage Guidelines

• Samples should be stored at 2 to 8 °C until shipment and must be received within 3 days (72 hours) from collection. If a delay is anticipated, serum must be separated from the clot and stored at -20 °C or lower.

Transportation Instructions

• If samples are submitted refrigerated, ship them on frozen cold packs to maintain a temperature of 2 to 8 °C.
• If serum samples are submitted frozen, ship them on dry ice to maintain a temperature of -20°C or colder.

Acceptable Arrival Temperature

• 2 to 8 °C if the sample is sent refrigerated.
• -20°C or colder if the serum sample is sent frozen.

Causes for Rejection

• Samples that are grossly hemolyzed, icteric, lipemic, broken or leaking in transit.
• The details on the specimen do not precisely correspond with the patient’s records.
• Quantity of serum sample is less than 500 µL.
• Specimen contains particulate matter or exhibits obvious microbial contamination.
• Specimen received outside of the acceptable arrival temperature range.
• More than 3 days have passed since the specimen was collected, and the serum was not kept frozen during this period.
