---|---|
Test NameAmylase Isoenzymes (Salivary Amylase, Total Amylase, Pancreatic Amylase) |
|
Specimen Type / RequirementsContainer Type = 1 Gold Top (SST) Minimum Testing Volume = 1mL serum Tube must fill to at least ½ or greater of its vacuum capacity |
|
Specimen HandlingCollection Instructions: Collect specimen in gold or red top tube. Write your initials, date and time of collection on the collection label or requisition. Laboratory Staff Instructions: Separate serum from cells within 2 hours of collection and freeze as soon as possible. Note: Salivary amylase is calculated as the difference between the two measured results (salivary amylase = total amylase-pancreatic amylase). Rejection Criteria: Gross hemolysis, unlabeled or samples of non sufficient quantity. Stability: Stable at room temperature for 1 week, refrigerated at 2–8°C for 1 month and frozen at -15°C to -20°C or lower for 6 months. Transportation: Send sample to core lab as soon as possible. |
