Warnex to perform pharmacogenetic services for Schering-Plough Canada

LAVAL, QC, Jan. 17 - Warnex Inc. (TSX: WNX) today announced that
its Medical Laboratories division will develop new pharmacogenetic assays and
serve as a central laboratory for several clinical studies of Schering-Plough
Canada, a leader in the discovery and development of pharmaceutical products.

"Pharmacogenetic assays allow the correlation of different responses to
drugs with genetic diversity and/or mutations, improving the overall process
of drug development," said Mark Busgang, President and CEO of Warnex. "In
2006, Warnex acquired PRO-DNA Diagnostics, a laboratory offering genetic
testing services, in order to enter the pharmacogenetics market. These new
projects with Schering-Plough Canada validate our strategy to develop our
presence in this growing market."

Pharmacogenetics helps to predict whether a patient will have a good
response to a drug, a bad response to a drug or no response at all. According
to the U.S. Food and Drug Administration Center for Drug Evaluation and
Research, over 2 million Adverse Drug Reactions ("ADRs") occur yearly leading
to more than 100,000 deaths yearly. ADRs are one of the leading causes of
hospitalization and death ahead of pulmonary disease, diabetes, AIDS and
pneumonia in the United States. By employing pharmacogenetic studies in drug
development, companies can increase the likelihood of a positive study result
by matching patients who are more likely to respond or alternatively not more
likely not to have an adverse event.

Warnex Medical Laboratories will provide pharmacogenetic and molecular
biology services during Schering-Plough Canada's clinical trials for drugs
related to the treatment of different types of cancer and infectious diseases.

Warnex Medical Laboratories focuses on genetic and biochemical testing
for the healthcare industry. The division performs testing in a wide range of
clinical specialties, including endocrinology, haematology, infectious
diseases, obstetrics/gynaecology, and oncology, and has extensive expertise in
genetic testing for human identification, molecular medicine, and
