    Transport

    For the CHOP enterprise, submit blood specimens as soon as possible at room temperature to Central Laboratory Services. For outside clients, it is recommended that plasma specimens be removed from the red blood cells or separator gel as soon as possible after collection and before shipping specimens. When shipping plasma specimens, package and label specimens in compliance with applicable state, federal, and international regulations covering the transport of clinical specimens and infectious

Disease Information

Utility:

The Rapid HIV-1/2 Antibody Test is ued by the laboratory to test source patients that have been involved in accidental exposures of healthcare workers to blood and body fluids and to test mothers receiving care at the Center for Fetal Diagnosis and Treatment and delivering their babies in the Special Delivery Unit. Employees involved in an accidental exposure to blood or body fluids from a source patient must contact Occupational Health and get prior authorization to order the test. The test can then be ordered as part of the Occupational Health Order Set in EPIC.

Interpretation

A positive result using the Rapid HIV-1/2 Antibody Test is presumptive and suggests the presence of HIV-1 and/or HIV-2 antibodies in the specimen. Ad

Reference Values
