ABN Requirement: No
Specimen:
Preferred: Serum
Alternative: EDTA Plasma
Volume:  3.0 mL
Minimum Volume:  2.0 mL
Container:
Preferred: Gel-barrier tube (SST)
Alternative: EDTA (Lavender Top) tube

Collection:

Serum:

  1. Collect and label sample according to standard protocols.
  2. Gently invert tube 5 times immediately after draw.
  3. Allow blood to clot 30 minutes.
  4. Centrifuge for 10 minutes.

EDTA Plasma:

  1. Draw and gently invert 8 to 10 times.
  2. Centrifuge for 10 minutes.
    EDTA plasma must be separated from cells within 2 hours of collection.
  3. Pre-squeeze transfer pipet bulb and draw off approximately 2/3 of the upper plasma layer.  Note: This ensures that the buffy coat and red cells remain undisturbed.
  4. Aliquot plasma into labeled transport tube as “EDTA plasma” and cap tightly.

Discard original tube.

Special Specimen Collection Instructions: Tube must be labeled with patient identifiers and submitted only for HIV testing. SST tube should be spun after clotting and remain unopened.

Transport: Store serum or EDTA plasma at 2°C to 8°C after collection and ship the same day per packaging instructions included with the provided shipping box.

Stability:

Ambient (15-25°C): 72 hours
Refrigerated (2-8°C): 5 days
Frozen (-20°C): 30 days

Causes for Rejection: Specimens other than serum or EDTA plasma; improper labeling; samples not stored properly; samples older than stability limits; frozen SST tube; gross hemolysis

Methodology: Immunoassay (IA)

Turn Around Time:  2 to 3 days

Reference Range:

Clinical Significance: This 4th generation HIV Ag/Ab Combo assay is intended to be used as an aid in the diagnosis of HIV1/HIV2 infection, including acute or primary HIV-1 infection.
