Press Release Body = ST. LOUIS - Lee Biosolutions has announced the production and
availability of human D-dimer, an antigen widely used as a marker for several vein
and artery related medical conditions. Its presence is used to identify the
incidence of blood clots in arteries and veins.

D-dimer is an end product that is created by plasmin-mediated degradation of
crosslinked fibrin clots. The measurement of D-dimer has proven to be a sensitive
marker for the evaluation of disseminated intravascular coagulation. D-dimer can
also effectively rule out patients with a low or a moderate probability of venous
thromboembolism, including deep vein thrombosis or pulmonary embolism.

According to Lee Biosolutions President Burton Lee, blood clots are responsible for
hundreds of thousands of death each year that may otherwise be prevented if the clot
were identified and diagnosed sooner.

"Pulmonary embolism alone is estimated to be responsible for as many as 200,000
deaths each year, and research by the American College of Chest Physicians suggests
that it may be the most easily preventable cause of hospital death ," Lee said.
"The lab studies that continue to be conducted with D-dimer are among the keys to
lowering that number."

While D-dimer is able to indicate the presence of a significant clot, it is unable
to indicate the location of the clot within the body. The D-dimer test is most
useful when it yields a negative result and is able to rule out clotting. The
D-dimer test is often administered with additional tests in the process of
diagnosing a disease or condition.
