New Abbott Vitamin D Test Available for Use in the European Union

ABBOTT PARK, Illinois, January 25, 2011 - Abbott (NYSE: ABT) has announced CE marking (Conformite Europeenne) for
the ARCHITECT 25-OH Vitamin D assay, a new diagnostic test to measure levels
of vitamin D in blood using Abbott's ARCHITECT automated instrument system.

According to the International Osteoporosis Foundation, vitamin D
deficiency is a global health issue. The percentage of the European
population that is vitamin D insufficient is high, with some countries
exceeding 75 percent. Global demand for patient testing is estimated to be
growing at 50 percent per year due to increasing medical knowledge of the
adverse health implications associated with vitamin D deficiency.

The ARCHITECT 25-OH Vitamin D assay is a fully-automated immunoassay that
can help laboratories manage the expected increase in vitamin D testing
volumes. It is intended for the quantitative determination of 25-hydroxy
vitamin D in human serum and plasma to aid in the assessment of vitamin D
sufficiency. The 25-hydroxy vitamin D test provides an accurate gauge of
vitamin D status, and its measurement in patients provides opportunities for
preventive and therapeutic interventions.

"As a major diagnostic lab, serum 25-OH vitamin D has become an
increasingly important diagnostic marker to us," said Dr. Frans AL van der
Horst, Reinier de Graaf Group, Diagnostic Center SSDZ, Delft, The
Netherlands. "There has been a great need for a reliable and cost effective
assay. With the introduction of the Abbott test, we can fulfill these needs
and significantly improve the efficiency of the workflow in our routine lab."

Low concentrations of vitamin D can cause secondary hyperparathyroidism
(high levels of parathyroid hormone or PTH) and diseases related to impaired
bone metabolism. When PTH is abnormally high, a person loses calcium from
his/her bones and has an elevated risk for bone density loss.

Consequently, low vitamin D levels can cause skeletal disorders, such as
rickets in children and osteopenia in adults, and have been linked to an
increased risk of hip fracture and falls. Studies have also shown that
vitamin D deficiency may increase risk for some cancers, cardiovascular
problems, autoimmune disorders and infectious diseases.

"Vitamin D deficiency is recognized as a global health problem, and
vitamin D supplementation should be considered for all people at risk of
vitamin D deficiency," said Jean-Claude Souberbielle, Ph.D., Hopital
Necker-Enfants Malades, Universite Paris. He added that determination of the
serum vitamin D concentration and supplementation according to the measured
level is important for patients with osteoporosis, chronic kidney disease,
abnormalities in absorbing food nutrients, and more generally, in those with
a disease or a treatment that may impair bone health.

"The new vitamin D assay is a valuable and convenient addition for Abbott
ARCHITECT customers, who now have an automated test to use on samples that
previously might have been sent to outside reference labs," said Brian
Blaser, senior vice president, diagnostic operations, Abbott. "This will save
labs time and money as they work to manage increases in the volume of vitamin
D tests they perform."

The ARCHITECT 25-OH Vitamin D assay is not approved for use in the United
States.
