Lysozyme, Serum (Muramidase)
Test Name Lysozyme, Serum (Muramidase)
Specimen Type / Requirements Container Type = 1 Gold Top (SST) Minimum Testing Volume = 1mL Tube must fill to at least ½ or greater of its vacuum capacity
Specimen Handling Collection Instructions: Collect sample in gold or red top with or without gel separator. Please provide age, gender and clinical history to facilitate interpretation of analytical findings and recommendation of further testing or consultation Write your initials, date and time of collection on the collection label. Special Instructions Centrifuge serum specimens within 1 hour of collection. Transfer serum to sterile transport tube. Delayed separation of the serum can result in spuriously high levels of lysozyme, presumably because of the breakdown of leukocytes. Store and send frozen. Rejection Criteria: Multiple freeze/thaw unacceptable, grossly hemolyzed, or lipemic, unlabeled or samples of non sufficient quantity. Stability: Stable at room temperature for 24 hours, 15 days refrigerated and 18 days frozen. Transportation: Send sample to core lab as soon as possible.
