Specimen Requirements

Container/Tube:

Preferred: Gold-top serum gel tube

Acceptable: Plain, red-top tube

Specimen: 160 uL of serum

Stability: If the assay is performed within nine days of sample collection, the samples may be kept at 2-8°C; otherwise they should be dispensed in aliquots and stored deep-frozen (–20°C or below). If samples are stored frozen, mix thawed samples well before testing.  Samples have shown stability up to six freeze-thaw cycles.

Collection Instructions: Serum should be separated from the clot as soon as possible.
