Acute Hepatitis Panel

EPIC: LAB5216, SOFT: AHPT

Instructions

Acute Hepatitis Panel includes:

Specimen Collection Criteria

Collect (preferred specimen): One Gold-top SST tube. (Minimum Whole Blood: 4.0 mL)
Also acceptable: One Lavender-top EDTA tube. (Minimum Whole Blood: 3.0 mL) 

Physician Office/Drawsite Specimen Preparation

  • Let SST specimens clot 30-60 minutes then immediately centrifuge to separate serum from cells. Refrigerate (2–8°C or 36–46°F) the centrifuged SST tube within two hours of collection. (Min: 2.0 mL)
  • Centrifuge Lavender-top tube immediately to separate plasma from cells. Transfer plasma to a plastic transport tube and refrigerate (2–8°C or 36–46°F) within twelve hours of collection. (Min: 2.0 mL)

Preparation for Courier Transport

Transport: Centrifuged SST tube or plasma aliquot, refrigerated (2-8°C or 36-46°F). (Min: 2.0 mL serum or plasma)

Rejection Criteria

  • Hemolyzed specimens.
  • Severely lipemic specimens.
  • Specimens that have gross bacterial contamination.
  • Red-top tubes with serum not separated from cells within two hours of collection.
  • Lavender-top tubes with plasma not separated from cells within twelve hours of collection.

Storage

Centrifuged SST tubes may be transported and stored at ambient temperatures (2o to 30o C; 36o to 86o F) for up to 48 hours. DO NOT FREEZE TUBES CONTAINING BLOOD. For longer storage, the serum should be removed from the gel and refrigerated (2o -8o C) or frozen at -20o C or below.

Red-top tubes and Microtainers® may be stored at ambient temperatures for up to 16 hours and for up to 3 days at refrigerator temperatures (2o - 8o C). DO NOT FREEZE TUBES CONTAINING BLOOD. For longer storage, the serum should be removed from the clot and refrigerated (2o -8o C) or frozen at -20o C or below.

Serum specimens (pour-overs) may be stored at room temperature (20o to 26o C; 68o to 79o F) for up to 1 week, refrigerator temperature (2o to 8o C; 36o to 47o F) for two weeks, and at -20o C (-4o F) for up to 3 months. Specimens stored at -70o C (-94o F) can be stored indefinitely. Avoid repeated freezing and thawing.
