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/Draw 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. (Minimum: 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. (Minimum: 2.0 mL)

Preparation for Courier Transport

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

In-Lab Processing

Let SST specimens clot 30–60 minutes. Centrifuge SST, Lavender-top tubes, or Microtainers® to separate serum or plasma from cells. Deliver immediately to the appropriate testing station.
