Apolipoprotein A1
Test Name Apolipoprotein A1
Specimen Type / Requirements Container Type = Gold (SST) Minimum Testing Volume = 1ml Serum Tube must fill to at least ½ or greater of its vacuum capacity
Specimen Handling Collection Instructions: Ensure both sample and requisition are labelled properly Serum or plasma, free from hemolysis, collected with or without gel separator. Write your initials, date and time of collection on the collection label. Laboratory Staff Instructions: Lipemic samples or frozen samples that become turbid upon thawing must be clarified by centrifugation (10 minutes at 15,000 x g). Separate serum or plasma from cells within 2 hours of collection. Thaw only once. Stability: Unfrozen samples can be analyzed if stored in a laboratory refrigerator for up to 7 days. Frozen samples are stable when stored at – 20°C for up to 3 months or when stored at – 70°C for up to 5 years. Thaw only once. Transportation: Transport at room temperature ASAP. Place on ice if time of collection to time sample get to lab exceeds 2hrs Sample Rejection Criteria: Unlabeled or Not Sufficient Quantity samples will be rejected. (i) Samples that have been thawed for more than 48 hours. Unlabeled or Not Sufficient Quantity samples will be rejected. (ii) Samples that have been refrozen
