For statistical analysis, samples were considered hemolyzed
if their hemoglobin concentration was greater than 0.
When recentrifuged, the hemolyzed
serum blends with the untainted scrum observed at the draw stations and leads to specimen rejection.
Furthermore, we obtained the same results for undiluted WB that was frozen at -70[degrees]C and hemolyzed
10 days later (main study 2).
Samples from the hospital emergency department were excluded because such samples have a high incidence of being grossly hemolyzed
They are typically very lipemic and significantly hemolyzed
Briefly, whole blood is hemolyzed
by addition of an acidic hemolysis solution.
Icteric and hemolyzed
serum samples might also be a problem in certain immunoassays (5).
There are also long-term sequalae from exposure to hemolyzed
blood, including impaired endothelial function, which further exacerbates the long-term cardiovascular risk for patients on hemodialysis.
why is the liquid portion of their blood sample clear, hemolyzed
, icteric or lipemic after its centrifugation)?
plasma collected in lithium heparin was submitted concurrently for a biochemical profile (Olympus AU400e; Olympus America Inc, Diagnostic Systems Division, Irving, TX, USA) and subsequently interpreted using previously established reference intervals for Amazon parrots (Table 1).
Estimated National Volume of Laboratory Results Affected by Hemolyzed
Specimens from Emergency Departments.
2) One study found that hemolyzed
samples yielded falsely normal activation partial thromboplastin times (APTTs).
