Biosite is voluntarily recalling one lot of its Triage Cardiac Panel, a test
used to aid in the diagnosis of MI [1]. The product has been recalled nationwide
in the US due to reports of low recovery of quality-control samples containing
creatinine kinase MB (CK-MB), troponin I, and myoglobin on the affected lot.

Although there have been no reports of patient misdiagnosis associated with this
lot--catalog 9700HS, lot #W444467B--which was distributed to labs in the US
between January and February of this year, Biosite has notified customers to
discontinue use of the affected lot and discard any remaining product.
