LYSOZYME SERUM

LAB1133

 

Collect

Serum separator tube (SST).

Specimen Preparation

Separate serum from cells ASAP or within 2 hours of collection. Transfer 1 mL serum to an ARUP Standard Transport Tube. (Min: 0.4 mL)

LACTATE DEHYDROGENASE (LDH)

LAB96

LDH

Collect

One 4.5 mL green top with gel (PST), (lithium heparin plasma).

Pediatric Collection

At least 0.5 mL blood in microtainer, green top with gel, plasma (lithium heparin).

Unacceptable Conditions

Frozen sample; sample not properly identified; insufficient sample volume.

Storage/Transport Temperature

Internal: Deliver to lab immediately at ambient temperature.
Offsite: Centrifuge within 2 hours of collection. For best accuracy, transport to lab at ambient temperature. Do not freeze (see Remarks).

Stability (from collection to initiation)

Before centrifugation: Ambient, 2 hours.

After centrifugation: Ambient, 24 hours; Refrigerated, 24 Hours; Frozen, unacceptable (do not freeze).

Remarks

Maintaining ambient temperature of the sample will provide the most accurate LD result. Freezing the sample will cause an immediate false decrease in LD value of approximately 10%. Refrigerated samples demonstrate a slow decrease of 10% after 24 hours.
