1.0 mL
  

Immediately following collection, thoroughly mix sample by gently inverting 5 times

  
  1. Allow sample to clot for a minimum of 30 minutes
  2. Spin within two (2) hours of sample collection
  

Gold serum separator (SST) tube

 

  
Heparin plasma
EDTA plasma
  

Red serum vial/tube, 5 mL

Dk green heparin (Li or Na), no gel

 

Lavender (EDTA), 4mL

  

Immediately following collection, mix sample thoroughly by gentle inverting 8 - 10 times, to prevent clotting

  

Lt green:

Spin within two (2) hours of sample collection

Dk green/lavender:

  1. Spin
  2. Transfer plasma to a False bottom plasma/serum transport vial/tube (AHL), labelled as the appropriate plasma type, within two (2) hours of sample collection
  

False bottom plasma/serum transport vial/tube (AHL)

  

Refrigerated - 7 days

  
  • Improper labels (unlabeled or mislabeled)
  • Hemolysis (some procedures)
  • Improper anticoagulant or ratio
  • Delay in transport
  • Improper storage temperature affecting results
  • Inappropriate timing of collection
  • Improper container
  • Leaking container resulting in compromised specimen
  • Quantity not sufficient (QNS)

HIV-1/HIV-2 Differentiation Assay results:

HIV-1

HIV-2

Interpretation

Positive

Non-reactive

Positive for HIV-1 Antibodies. Suggest follow-up testing: HIV-1 RNA Quant (7867/LAB7867)

Non-reactive

Positive

Positive for HIV-2 Antibodies. Suggest follow-up testing: HIV-2 DNA (Mayo Clinic Laboratories)

Non-reactive

Non-reactive

HIV Ag/Ab combo test is positive, presumably due to presence of HIV p24 Ag, non-reactive for both HIV-1 and HIV-2 antibodies, Suggest follow-up testing: HIV-1 RNA Quant (7867/LAB7867)

Indeterminate

Indeterminate

HIV Ag/Ab combo test is positive, possibly due to presence of HIV p24 Ag as differentiation assay is indeterminate for both HIV-1 and HIV-2 antibodies, Suggest follow-up testing: HIV-1 RNA Quant (7867/LAB7867)

Indeterminate

Positive

Indeterminate for HIV-1 and positive for HIV-2, Suggest follow-up testing: HIV-1 RNA Quant (7867LAB7867), HIV-2 DNA (994/LAB994, Mayo Clinic Laboratories)  

Positive

Indeterminate

Indeterminate for HIV-2 and positive for HIV-1, Suggest follow-up testing: HIV-1 RNA Quant (7867/LAB7867)

Positive

Positive

HIV positive but undifferentiated, additional testing recommended Suggest follow-up testing: HIV-1 RNA Quant (HVL) Positive for HIV-2 Antibodies, HIV-2 DNA (994/LAB9994, Mayo Clinic Laboratories)
