Reference Range

Negative (reported as Negative or Sent for Confirmation*)

Repeatedly reactive samples referred to UCI Laboratories for confirmation.

INTERPRETIVE GUIDELINES:

NEGATIVE:

Specimen was non-reactive for HIV-1 and HIV-2 antibodies, and p24 antigen.  A negative test result does not exclude the possibility of exposure to or infection with HIV.  HIV antibodies and/or p24 antigen may be undetectable in some stages of the infection and in some clinical conditions.

SENT FOR CONFIRMATION:

Sample sent to reference lab for confirmation using supplemental tests for HIV-1/HIV-2 antibodies and/or p24 antigen.  In specimens giving indeterminate supplemental test results, testing of a subsequent sample drawn at a later date (such as 1-6 months) is recommended.
