PUBLIC REPORT
Product: Abbott RealTime HIV-1 (Manual)
Number: PQDx 0146-027-00
Abstract
The Abbott RealTime HIV-1 (Manual) assay with product code 2G31 (which includes 2G31-
90, 2G31-80, 2G31-70) manufactured by Abbott Molecular Inc., 1300 East Touhy Avenue,
Des Plaines, IL 60018, United States of America, CE-marked regulatory version, was
accepted for the WHO list of prequalified diagnostics and was listed on 17 October 2011.
This version of the product is intended to be used in conjunction with the following
instruments/reagents: 9K15-01, 2G31-66, 1L68-09 (or higher), 04J70-24 and 4J71-93.
The Abbott RealTime HIV-1 (Manual) assay is an in vitro reverse transcription-polymerase
chain reaction (RT-PCR) assay for the quantitation of Human Immunodeficiency Virus type
1 (HIV-1) in human plasma from HIV-1 infected individuals. The Abbott RealTime HIV-1
(Manual) assay is intended for use in conjunction with clinical presentation and other
laboratory markers as an indicator of disease prognosis and for use as an aid in assessing
viral response to antiretroviral treatment as measured by changes in plasma HIV-1 RNA
levels. This assay is not intended to be used as a screening test for HIV-1 or as a diagnostic
test to confirm the presence of HIV-1 infection.
The Abbott RealTime HIV-1 (Manual) assay uses RT-PCR to generate amplified product
from the RNA genome of HIV-1 in clinical specimens. An RNA sequence that is unrelated to
the HIV-1 target sequence is introduced into each sample at the beginning of sample
preparation. This unrelated RNA sequence is simultaneously amplified by RT-PCR, and
serves as an internal control (IC) to demonstrate that the process has proceeded correctly
for each sample. The amount of HIV-1 target sequence that is present at each
amplification cycle is measured through the use of fluorescent-labeled oligonucleotide
probes on the Abbott m2000rt instrument. The amplification cycle at which an increase in
fluorescent signal is detected by the Abbott m2000rt is proportional to the log of the HIV-1
RNA concentration present in the original sample.
In order to perform the assay, the following components are required:

The Abbott RealTime HIV-1 (Manual) was accepted for the WHO list of prequalified
diagnostics on the basis of data submitted and publicly available information.
Background information
Abbott Molecular Inc. submitted an application for prequalification of Abbott RealTime
HIV-1 (Manual). Based on the established prioritization criteria, Abbott RealTime HIV-1
(Manual) was given priority for prequalification.
Product dossier assessment
In 2011, Abbott Molecular Inc. submitted a product dossier for Abbott RealTime HIV-1
(Manual) as per the ‘Instructions for compilation of a product dossier’ (PQDx_018 v1). The
information submitted in the product dossier was reviewed in accordance with the
‘Internal report on the screening and assessment of a product dossier’ (PQDx_009 v2) by
WHO staff and external experts (assessors) appointed by WHO. Based on the product
dossier screening and assessment findings, a recommendation was made to accept the
product dossier for Abbott RealTime HIV-1 (Manual) for prequalification.

Commitments for prequalification:
The manufacturer has amended and submitted additional documentation as per the
product dossier assessment findings. No further amendments are required.
Manufacturing site inspection
An inspection was conducted at the site of manufacture (1300 East Touhy Avenue, 60018
Des Plaines, IL, USA) of the Abbott RealTime HIV-1 (Manual) on 29 June-1 July 2011 as
described in ‘Information for manufacturers on WHO prequalification inspection
procedures for the sites of manufacture of diagnostics (PQDx_014 v1)’.
The inspection found that the manufacturer had a well-established quality management
system and manufacturing practices in place that would ensure the manufacture of a
product of consistent quality. The manufacturer's responses to the nonconformities noted
at the time of the inspection were accepted on 29 September 2011.
Commitments for prequalification:
1. Risk Management Files will be updated to include risk analysis for end users in
resource limited and environmentally challenging regions to which the product is
distributed. This will apply to the Abbott RealTime HIV-1 (Manual) product as well
as to the related products.
2. Abbott Molecular Inc. has committed to work towards improving communication
(e.g. customer feedback mechanisms, tailored training, labeling) for users in
resource limited regions where communication may be problematic.
Laboratory evaluation
Given the regulatory version of the product submitted for prequalification and the quality
of the data submitted as part of the product dossier to support the claims for its intended
use, the Abbott RealTime HIV-1 (Manual) assay has been found eligible to undergo the
WHO fast track procedure. Subsequently, the product will not be required to undergo a
laboratory evaluation for its use with human plasma.
Nevertheless, taking into consideration the needs of WHO Member States and in an effort
to support current attempts to increase access to HIV Viral Load testing, a laboratory
evaluation of the Abbott RealTime HIV-1 (Manual) will be carried out to assess its
performance with the use of Dried Blood Spots (DBS). It is acknowledged that this
constitutes an off-label use of the product and therefore, results from the evaluation will
not impact the WHO Prequalification status for use with human plasma. The results from
the evaluation will serve as a source of information in order to advise WHO Member States
in their efforts to scale up HIV Viral Load Testing.
