1. Quantity not sufficient (QNS)
2. Specimen was not labeled with at least 2 unique patient identifiers
3. Information on specimen does not match requisition/test order
4. Specimen leaked in transit
5. Specimen was received out of the acceptable temperature range
6. Received greater than 7 days after collection at 2-8° C

Collection Media

Storage Conditions

Store specimens at 2-8° C or frozen at less than or equal to -20° C until shipment. Ship within 4 days of collection.

Packaging and Shipping

Specimens must be shipped overnight at 2-8° C or frozen on dry ice at less than or equal to -20° C. If you store the sample frozen, it must be shipped frozen to avoid a freeze thaw cycle.

Couriered samples must be transported in a cooler with frozen ice packs to arrive at the laboratory between 2-8° C. Laboratory staff will check the temperature of the cooler upon arrival before accepting specimens.

Interferences and Limitations

Do not use the antibody titer of a single serum specimen to determine recent infection.

Samples collected too early in course of an infection may not have detectable levels of IgG.
