TETERBORO, N.J. (Reuters) - Quest Diagnostics Inc., a provider
of gene-based medical testing, information and services, said
on Tuesday that it and the Center for AIDS Research at the
Stanford University School of Medicine have found strain of
HIV-1 that is resistant to antiviral drugs.
The strain has reduced susceptibility to reverse transcriptase
inhibitors, a class of antiviral drugs, Quest said.
Identification of this new mutation gives physicians additional
information that allows them to better target effective
treatment of HIV-1 in their patients, Quest said.
The findings, which were published in the November Journal of
Virology, are being used by Quest to report laboratory results
for its HIV-1 genotyping test, the company said.
