Spectral Presents Data on West Nile Virus Rapid 1 Assay at the American Association for Clinical Chemistry (AACC) Meeting

· Issued by Spectral Medical Inc via CNW
TORONTO, July 24 /CNW/ - Spectral Diagnostics Inc. (SDI: TSX) today
reported key advances that contributed to the development of Spectral's novel
rapid diagnostic test for West Nile Virus. The data is being presented at the
AACC 2006 annual meeting in Chicago, July 23 to July 27. The AACC is the
largest meeting in the world for the business of laboratory medicine. Spectral
is making a total of four scientific presentations, demonstrating its leading
work in the area of rapid and accurate detection of West Nile Virus infection.

"Spectral scientists are presenting key advances showing our strength in
assay development," stated Dr. Paul Walker, President and CEO. "These include
development of the necessary recombinant proteins, antibody purification, and
sensitivity and specificity of this assay. Spectral is filing for patents
relating to its leading work in this area," he added.

Spectral's West Nile Virus Rapid 1 assay is the first test designed to
provide rapid results in less than one hour to clinicians assessing and
treating individual patients in the acute setting. This also makes it useful
for public health personnel in the early detection of outbreaks. The test has
regulatory approval and is commercially available in Canada. Spectral is
actively engaged in the regulatory process for other major markets.

West Nile Virus infection is a mosquito borne illness that is believed to
have infected tens of thousands of patients in North America since its
emergence in the last several years. Many patients with West Nile Virus
infection will be unaware of it, or may have non-specific symptoms of fever,
headache, malaise, or other flu-like symptoms that are difficult for
physicians to diagnose. Current testing practices may take up to two weeks to
provide clinical results. According to the U.S. Centers for Disease Control,
about 1 in 150 patients infected with WNV will develop a serious infection
such as encephalitis or meningitis, which can result in paralysis or even
death. Already this year (2006) in both Canada and the United States there
have been reported cases of West Nile Virus infection and associated deaths.

Spectral is a developer of innovative technologies for comprehensive
disease management. Spectral provides accurate and timely information to
clinicians enabling the early initiation of appropriate and targeted therapy.
Current products include Spectral's rapid West Nile Virus assay and its FDA
approved rapid diagnostic for sepsis, the EAA(TM), as well as a range of other
biological reagents. Spectral's common shares are listed on The Toronto Stock
Exchange: SDI.
