Lipoprotein(a), LPA
Test Name Lipoprotein(a), LPA
Specimen Type / Requirements Container Type = Gold (SST) Li-heparin or EDTA plasma are acceptable. Minimum Testing Volume = 0.5 mL serum Tube must fill to at least ½ or greater of its vacuum capacity
Specimen Handling Collection Instructions: Collect specimen in a gold (preferred), red, green or EDTA tube. Laboratory Staff Instructions: Separate samples from cells within 8 hours of collection. Stability: The specimen is stable at room temperature for 24 hours, refrigerated for 7 days, frozen for 3 months (-20°C) or 6 months (-70°C). The sample should be thawed only once. Transportation: • Samples from UHT can be transported at room temperature. • Referral sites should send specimensfrozen (preferred), or at 2–8°C if delivery is within 7 days. Sample Rejection Criteria: Samples will be rejected if they are unlabeled, of insufficient quantity, thawed for more than 7 days, older than 7 days before being frozen, or if they have been refrozen after thawing.
